Arduino Tutorial 6 Arduino AnalogRead using ...

20200531· Here we using a 10k ohm pot. Its resistance can change from 0 to 10 k ohm. When Potentiometer pin 1 connects to + 5v supply and Pin 3 connects to the ground, then we get analog voltage at pin 2. That you’re can reading as an input. When the pot shaft is turned all the way in one direction, there are 0 volts going to the pin, and the input value is 0. When the pot shaft is …
