      For the voltage variable one, is it still wired in series?

    • @Automatedo
      @Automatedo  Před rokem +1

      Yes, a voltage variable potentiometer (also known as a voltage divider) is still wired in series with the circuit. In this configuration, the potentiometer is used to divide the voltage between its two output terminals, which are connected to the rest of the circuit.
      By adjusting the position of the potentiometer's wiper, the voltage output from the potentiometer can be varied, allowing for precise control of the voltage supplied to the circuit.
      It's important to note that in this configuration, the potentiometer's resistance value should be chosen based on the current requirements of the circuit, and the maximum voltage that will be present across the potentiometer. Exceeding either of these limits can cause the potentiometer to overheat or fail.

    I have a question, for the example at 3:10 ..... why does the left terminal have both black wires? Couldn't the left terminal not be used at all and go straight from the negative battery to the motor?

    • @Automatedo
      @Automatedo  Před rokem +2

      While a potentiometer with only two pins can be used for motor speed control, a potentiometer with three pins can offer additional flexibility for controlling other aspects of the motor control circuit, such as the direction of rotation or the duty cycle of a pulse width modulation (PWM) signal.
      For example, in a motor control circuit that uses PWM to control the motor speed, the third pin of the potentiometer can be connected to the PWM input, allowing the potentiometer to control both the duty cycle and the speed of the motor.

    Note: Never exceed the current through the potentiometer's rating or "Wattage" For Higher currents use a transistor [BJT or Mosfet] to control the load with the Pot controlling the transistor.

    • @Automatedo
      @Automatedo  Před rokem +3

      Thank you for the comment! You are absolutely correct. It is important to ensure that the current flowing through the potentiometer does not exceed its wattage rating. Exceeding the wattage rating can cause the potentiometer to overheat and even burn out.
      Using a transistor such as a BJT or Mosfet to control the load with the potentiometer controlling the transistor is a great way to ensure that the current through the potentiometer stays within its rated limit. This configuration is commonly known as a voltage divider circuit and is a widely used technique in electronics.

    I'm new to electronics so forgive me for my stupid question. Please help me understand? At 4:46 you said: "If we adjust the wiper in a way that introduces high resistance, more voltage will drive to the motor, resulting in turning the DC motor faster." The motor IS running faster as you said BUT at this point the negative terminal on the battery is connected directtly to one terminal on the motor while the positive terminal from the battery takes the shortest path trhough the POT going straight via the wiper to the other terminal on the motror. Isn't this the LEAST resistance for the current? Why do you say the opposite of what seems to he happening?

    • @Automatedo
      @Automatedo  Před rokem +1

      In general, if a potentiometer is used as a voltage divider to control the speed of a DC motor, introducing more resistance will lead to a slower motor speed.
      However, there may be certain cases (the illustrated example in this video) where introducing more resistance could result in a higher motor speed.
      For example, if the motor control circuit is designed to work with a specific range of potentiometer resistances, and the resistance is currently too low, introducing more resistance to bring it into the appropriate range could result in a higher motor speed.

  • @Albertmars32
    @Albertmars32 Před rokem +19

    Couldn't you have achieved the same thing with the motor by using the first configuration? Only use 2 pins from the potentiometer and if you want to increase the speed of the motor just decrease the potentiometer resistance, and if you want to decrease the spin then add more resistance. I fail to see how using the third pin is useful for adjusting the speed when you can just use 2 pins. Can someone explain please

    • @Automatedo
      @Automatedo  Před rokem +3

      While a potentiometer with only two pins can be used for motor speed control, a potentiometer with three pins can offer additional flexibility for controlling other aspects of the motor control circuit, such as the direction of rotation or the duty cycle of a pulse width modulation (PWM) signal.
      For example, in a motor control circuit that uses PWM to control the motor speed, the third pin of the potentiometer can be connected to the PWM input, allowing the potentiometer to control both the duty cycle and the speed of the motor.

    • @tanner1985
      @tanner1985 Před rokem +5

      The difference is subtle. If you use all the 3 pins, you are employing not a variable resistor, but a voltage divider (see voltage divider in the internet to know more). In this case, the whole voltage of, say, a battery, is supplied to the whole device (suppose 6V). The DC motor is connected to the wiper and one of the legs of the potentiometer. The resistance of the part NOT connected to the DC motor determines the fall of potential, so if that resistance is low, the drop of voltage will be low and more voltage will remain for the part connected to the DC motor. This results in the fact that the more resistance is dedicated to the part of the DC motor, the more power it gets. It is a little bit brainy but if you follow the reasoning you soon well realize that it is really that way.

      ​@@tanner1985 that's what is happening, but *why* is the voltage divider preferred over a variable resistor?

    • @deang5622
      @deang5622 Před rokem +1

      A voltage divider allows you to take a voltage and produce a lower voltage.
      They typically comprise a couple of fixed resistors.
      By using a potentiometer you can make that output voltage variable.
      Using a potentiometer in a 2 pin arrangement gives you a variable resistor, not a voltage divider.
      It is just a resistor which is changeable.
      And a resistor sets the current.
      A changing resistor allows you to change the current.
      So it all depends on what you are trying to do, what you actually need for your application, do you want a fixed or variable voltage: => voltage divider or potentiometer, or do you want to set a current to a desired magnitude or changeable magnitude: => resistor or potentiometer using two pins.

  • @olenfersoi8887

    That is very good info, clearly explained. But, for audiophiles, it would be great to know the effect on voltage & amperage, in each case, when the same identical potentiometer is used as a tone vs a volume control. From this video, and my knowledge that a volume control is a voltage divider...can I presume that tone control is varying amperage along with resistance? And, if so, what is the science between variations in resistance & amperage on the dominant tones or resonant peak of an audio signal???

  • @julianbeyblade3858

If I connect the cable to the 3 pin(negative) and would turn it counterclockwise that the resistance increases and the led becomes weaker and if I turn it clockwise it gets brighter? so the exact opposite as mentioned in the video, thanks for replying😊

      The TSR 24KN potentiometer has a nominal resistance of 200kΩ. However, it is possible that your scooter's control system may have been designed to work with a potentiometer of a different resistance value.
      To ensure compatibility and avoid potential damage to your scooter's control system, you should refer to the manufacturer's documentation to determine the correct replacement potentiometer for your mobility scooter.

    • @Automatedo
      @Automatedo  Před rokem

      Yes, it should be safe, as long as the motor and the potentiometer are rated for the same or higher voltage than the battery.
      However, using a 50k potentiometer may not be the most appropriate for controlling the speed of a 12-volt DC motor because it may not provide enough resolution or precision to accurately control the motor speed.

    Can i put potentiometer between the speaker and the dvd componant to increase or decrease volume of the speaker individually ,????
    Plz help

    • @Automatedo
      @Automatedo  Před 7 měsíci

      Yes. To do this, you will need a potentiometer with the same resistance as the speaker. You can find the resistance of your speaker by looking at its specifications or by measuring it with a multimeter.
      Once you have a potentiometer, you will need to connect it in series with the speaker. To do this, connect one end of the potentiometer to the positive terminal of the speaker and the other end of the potentiometer to the positive terminal of the DVD component. Connect the negative terminal of the speaker to the negative terminal of the DVD component.
      Once the potentiometer is connected, you can adjust the volume of the speaker by turning the potentiometer knob. Turning the knob clockwise will increase the volume, and turning the knob counterclockwise will decrease the volume.

  • @JC-ig4xy
    @JC-ig4xy Před 3 měsíci

    Great video! However there is one part that isn't clear to me. Please tell me if I understand this part correctly. The resistance in a potentiometer depends on the length of the resistance element. When you adjust the knob on a potentiometer, the wiper either shortens or lengthens the element. Therefore, a longer element will have more resistance, while a shorter element will have less resistance. For instance, in volume control, the longer the resistance element when you turn it down, the lower the volume and the shorter the element when you turn it up, the higher the volume. As someone who had no prior knowledge of electronics, I thought the resistance element inside the pot had different points of resistance as opposed to the wiper actually shortening and lengthening the resistance element.

      In general, if a potentiometer is used as a voltage divider to control the speed of a DC motor, introducing more resistance will lead to a slower motor speed.
      However, there may be certain cases (the illustrated example in this video) where introducing more resistance could result in a higher motor speed.
      For example, if the motor control circuit is designed to work with a specific range of potentiometer resistances, and the resistance is currently too low, introducing more resistance to bring it into the appropriate range could result in a higher motor speed.

    • @deang5622
      @deang5622 Před rokem

      It depends on how the potentiometer is used.
      If you use it in a 2 pin configuration then you have a variable resistance and as the resistance increases the current through it will lower.
      If you use it in a 3 pin configuration, you are creating a potential divider (you will need to research yourself the theory of operation and the math behind it).
      Here the output is a voltage (not a current) across the resistance between one of outer pins and the middle wiper pin. Ohms Law says: V=IR, increase the resistance for a given value of current and the voltage across that resistance increases.
      So when used as a potential divider, and the output is across a variable resistance in the potentiometer, then as that resistance increases, the output voltage increases.

    Can you explain to me how to select the value of potentiometer such that when I have a supply voltage of 9 volts, and I draw 50 milliamps of current, the voltage doesn't drop by more than 0.1 volt?

    • @Automatedo
      @Automatedo  Před rokem

      Indeed, selecting the appropriate potentiometer value can be a bit tricky. To answer your question, you'll need to calculate the resistance value of the potentiometer based on the voltage drop and current draw specifications. You can use Ohm's law (V = IR) to solve for the resistance value. Resistance value = 0.1 / 0.05 = 2 ohms. However, keep in mind that potentiometers have a limited power rating, so you should also make sure that the potentiometer can handle the current draw without overheating or exceeding its power rating.

    How would this thing work on a lathe motor whereby you starve the motor of current, to slow the speed of the motor, then introduce, a heavy load to it. Will that burn the motor out in short order?
    And how reliable are these units per-se, are they themselves prone to failing?
    Thanks.

    • @Automatedo
      @Automatedo  Před 8 měsíci

      When it comes to controlling the speed of a motor, especially in applications like a lathe where heavy loads are involved, it is important to consider the motor's specifications and limitations. While a potentiometer-based voltage divider method can be used for speed control, it may not be the most suitable or reliable method for high-power applications like lathes.
      In scenarios where you want to slow down the motor by starving it of current and then introduce a heavy load, it can lead to increased stress and strain on the motor. This can potentially result in overheating, reduced efficiency, and even motor failure if the motor is not designed to handle such loads.
      For heavy-duty applications like lathes, it is recommended to use motor control techniques specifically designed for high-power and variable-speed operations. This typically involves using motor controllers, motor drivers, or specialized speed control systems that can handle the power and current requirements of the motor while providing better control and protection mechanisms.
      Regarding the reliability of these control units, it depends on the quality of the components, the design of the circuit, and the operating conditions. While potentiometers themselves are generally reliable, other components in the control circuit, such as transistors or motor drivers, may be more prone to failure if not properly selected or protected.

    • @Automatedo
      @Automatedo  Před 8 měsíci +1

      While a potentiometer with only two pins can be used for motor speed control, a potentiometer with three pins can offer additional flexibility for controlling other aspects of the motor control circuit, such as the direction of rotation or the duty cycle of a pulse width modulation (PWM) signal.
      For example, in a motor control circuit that uses PWM to control the motor speed, the third pin of the potentiometer can be connected to the PWM input, allowing the potentiometer to control both the duty cycle and the speed of the motor.

    at 4:43, the ( + ) and the ( - ) of the battery are technically connected to each other and form a closed circuit, won't this overheat the battery and damage it ??????🤔🤔🤔

    • @Automatedo
      @Automatedo  Před rokem

      The + and - terminals of the battery are indeed connected to each other in a closed circuit when connected to the potentiometer and motor in a voltage divider configuration. However, this does not necessarily lead to overheating or damage to the battery.
      In a voltage divider circuit, the current flowing through the circuit is determined by the total resistance of the circuit and the applied voltage. The potentiometer and motor act as resistors in the circuit, and the resistance of the potentiometer can be adjusted to control the amount of current flowing through the circuit.
      As long as the potentiometer is properly adjusted to limit the amount of current flowing through the circuit, the battery should not overheat or be damaged. It is important to choose a potentiometer with a suitable power rating and to calculate the appropriate resistance values to ensure safe operation of the circuit.

These pins are usually interchangeable and do not have any special significance other than their connection to the resistive element.
