The wiper of the 10K potentiometer is wired to A0 of Arduino (5V-A0-GND), while anode (A) of the test LED is linked to D5 through a 220Ω-470Ω resistor and cathode (K) to GND. #include ...

See the next Arduino hardware setup and accompanying sketch for the experiment. To test the sketch, just open the serial monitor of the Arduino IDE, type “1” into the text box, and press the “Send” ...

This simple setup serves as a foundation for demonstrating the basic functionality of GPIO control. The LED can be switched on and off, while the push button allows for user interaction and input ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...
