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 ...

This program uses three potentiometers for RGB control and displays the resulting color on an RGB LED. - fyemane/Arduino-Control-RGB-LED ...

Here is a simple, yet useful circuit of an Arduino 4-digit 7-segment LED display unit. The module used here is a self-contained, compact common-cathode module containing four 7-segment LED numeric ...

This paper describes a memristor emulator made up of an arduino-controlled digital potentiometer (DigPot) implementing the mathematical equations governing the HP memristor model. The emulator ...
