    Thank you very much.
    I have been searching for a couple of weeks, and your video is the ONLY one that gave a complete solution; meaning covering the programming stages (code + connections) on BOTH ESP2866 and Arduino!
    Best regards.

    @jsmythib Před 2 lety +6

    This was the straight forward tutorial I was looking for! Once the 3.3v regulated is powering the esp8266, its digital output are still recognized by the 5v arduino inputs. However, in a perfect world I would use a voltage divider to lower the digital output from the arduino to esp @ 3.3v. OK, Im going to try. Thanks you :)

    Thanks for mentioning about the voltage regulator ... I would have used the onboard 3.3v ... after investigating the uno and Mega2560 they both only supply 50mA ... The esp8266-01 can use as much as 170mA during transmit. I will probably try it with 2 - AA batteries ... only 3v but i am guessing it will still work fine.

    I also ran into the 'Times out waiting for packet header' error. Only after using my first Arduino board (lolon d1 mini v3.1.0) for not even an hour. I am a beginner and I don't understand the troubleshooting process and the comments so far on this problem still leave me clueless how to proceed. I have another board, but I have no idea why it got bricked so easily so I don't want to try that one now.

    Can it be restored without doing hardware stuff? Just by connecting it with the USB? Any help is greatly appreciated.

    • @techsteering
      @techsteering  Před 5 lety

      This can be achieved in multiple ways. Place a motion sensor/ distance measuring sensor (ultrasonic)/ touch sensor with door bell and send the signal through bluetooth or MQTT to the Raspberry pi. On receiving the signal, Raspberry pi could execute the command to click the picture. If you are using a foscam, check for foscam APIs. They also provide this feature for developers.

    You have got good teaching video. Thank you! But would you help me in similar case - I have got ESP-01 adapter, where I can plug my ESP8266. It has 8 pin connector and out I get 4 pins - VDD, GND, RX, TX. I would like to control, for example, a LED with Mobile phone. So I need to connect it somehow to Arduino (which I can maybe figure out myself), then I need some S/W to connect with my mobile phone to me ESP8266 (like to Bluetooth HC-06 module), which I believe I can find in Internet, but how about Arduino code? How to program Arduino to receive signals and to operate LED?
    Thank you in advance!
    BR,
    Valters

    • @techsteering
      @techsteering  Před 5 lety +1

      I would recommend to use ESP8266 Dev Board + LED + Mobile to achieve what you are looking for and skip Arduino. The reason I am saying that is you could achieve what you want without Arduino. For some specific reasons, if you wish to use Arduino then you have following choices: 1. Use combination of Arduino + LED + Mobile + Bluetooth module and control LED from your mobile using bluetooth. In this case, you don't need to use ESP-01 2. Let's say you wish to control throught WiFi. Then use Arduino + ESP-01 + LED + Mobile + MQTT (CloudMQTT). Mobile will send the on/off request to MQTT. You can download an existing MQTT app for mobile. ESP-01 will be a subscriber for MQTT. As soon as, mobile sends the on/off request to MQTT, ESP being a subscriber will receive the same. Next, ESP will pass on the on/off request to Arduino through serial communication and Arduino will turn the LED on/off basis on the instructions it has received. Further, in option 2, you can still choose to skip Arduino, ESP-01 and use ESP8266 dev board instead. Personally, I would prefer to use serial communication where something is already designed using Arduino and I need to extend the functionality using ESP. For example: Let's say an arduino based car is already designed and now I want to control it using Alexa voice commands. In this scenario, I will add ESP-01 on top of Arduino. Hope this helps.

    • @techsteering
      @techsteering  Před 5 lety +1

      I believe your question is, "Can I connect nodemcu with UNO WITHOUT regulator ?" Here, I am assuming that when you are saying..."NodeMCU", you mean ESP-01 board and not the NodeMCU development board. Assuming that my assumption is correct, answer is...if you are lucky, it would work for you. You need to use 3.3 v from UNO instead of 5v and rest of the process would remain same. The challenge you would face is to upload code on ESP-01. If it does not work, you would keep struggling for hours. Though if you use 3.3v regulator, it would surely run for you. So, my vote is with using regultor. Though you can still give it a try. Don't attempt to use 5v directly with your ESP-01. It may destroy your ESP. Hope this helps.
