![]() The board features 54 digital pins, 16 analog input pins, and four serial ports. Powered by the ATmega2560 chip, which has 256K bytes of Flash program memory, 8k bytes of SRAM and 4K bytes of EEPROM. Wokwi Online Simulator Arduino Electronic – Arduino Mega 2560Īrduino Mega 2560. It is powered by the ATmega328p chip, which has 32K bytes of Flash program memory, 2k bytes of SRAM and 1K bytes of EEPROM. Rotate the potentiometer and see the values changing.Wokwi Online Simulator Arduino Electronic – Arduino UnoĪrduino Uno – is the most popular board in the Arduino family. Testing the ExampleĪfter uploading the code and pressing the ESP32 reset button, open the Serial Monitor at a baud rate of 115200. Make sure you have the right board and COM port selected in the Tools menu. potValue = analogRead(potPin) įinally, print the values read from the potentiometer in the serial monitor. In the loop(), use the analogRead()function to read the analog input from the potPin. In the setup(), initialize a serial communication at a baud rate of 115200. In the code, you start by defining the GPIO the potentiometer is connected to. This code simply reads the values from the potentiometer and prints those values in the Serial Monitor. variable for storing the potentiometer value Potentiometer is connected to GPIO 34 (Analog ADC1_CH6) Open your Arduino IDE and copy the following code.
