Each LED is connected to one of the Arduino's digital output pins through a 220Ω resistor. A push button is connected to each input pin and uses the internal pull-up resistor feature of the Arduino.

The project controls the lighting of three LEDs using three independent buttons. When any button is pressed, the corresponding LED is turned on. What exactly does the project do? Contains: • Arduino ...

Many previous Design Ideas [1, 2] have shown how to use the Charlieplexing technique [3] to drive as many LEDs as possible with a minimum number of I/O lines. This Design Idea shows how you can drive ...

Building IoT projects with touchscreens used to be a headache, involving numerous components, messy wiring, and endless troubleshooting. But the ESP32-S3 Box-3 makes things way easier. It is an all-in ...

I made this Arduino 8 bit binary led counter as a solution for one member from Arduino forum. He asked if somebody can make a project that displays a decimal number in 8 bit binary format using 8 leds ...
