Very helpful, thank you!
Very well explained, as always!
I use a potentiometer to control the speed of a Stepper Motor. The Pot reading is mapped to a number that is used for the delay between HIGH and LOW for the voltage sent to the Stepper Driver. This works well except with a very short delay, the motor can stall. I need to "ramp up" the motor speed to avoid stalling. How could I take the Pot reading and if it is a very small number (short delay), use a higher number and increment slowly to the Pot reading? Thanks Mario! Regards.
Very simple explanation for us newbies. Thanks for the video and look forward to the next one.
Thanx. Don't forget to give video a like:)
Fantastic teaching ☕️🙏
You are too kind:)
Nice job Mario
Thank you:)
Any thoughts why my B10k potentiometer reads 0-255 for the first quarter of turning, and then if I turn just a little more, it starts back at 0 all the way to 255 again as I keep turning, and does this two more times? As I turn the knob clockwise from one end to the other, the values are: 0-255, 0-255, 0-255, 0-255
Not sure. My immediate reaction would be that there is something wrong with it. Do you have just one?
good job
Give video alike if you have not done already.
I understand 3-pin potentiometer configuration. But there is some circuits that use only 2 pin of potentiometer. Why is that? Why does it work?
Have you watched my entire video?😉
@@marios_ideas Oh at around 2 minute. Sorry. Sometime I just skip the video.
