Now that your setup has been completed, move into the main loop of your code. When your button is not pressed, the internal pull-up resistor connects to 5 volts. This causes the Arduino to report "1" or HIGH. When the button is pressed, the Arduino pin is pulled to ground, causing ...
Arduino AnalogRead Example Code Upload this code to Arduino. This code measures analog signal from A0 pin of Arduino every one second and prints value on serial monitor. //Potentiometer is connected at analog pin 0: int analogPin = A0; int val = 0; //variable to store the value read voi...
Code README Apache-2.0 license ESP32 LNA One of features of ESP32 that has been intriguing me since its release back in September 2016 waslow noise amplifier(LNA). Together with other analog components likeHall sensor,temperature sensor,capacitive touch sensor,cosine waveform generator, as well ...

In the code, you start by defining the GPIO the potentiometer is connected to. In this example,GPIO 34. constintpotPin=34; In thesetup(), initialize a serial communication at a baud rate of 115200. Serial.begin(115200); In theloop(), use theanalogRead()function to read the analog input...
That is sufficient for most things. Check out the header file for more functions and constants. Also check out the example code for better illustrations of usage. A lot of code was reference fromthis GitHub repo. I made a fair amount of modifications, but the repo can also probably be use...
