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 ...

A resistor and an LED will often suffice. Powering the LED means one thing and not powering it means another. And with seven more LEDs you can even display 0-255 in binary.

When you’re debugging a board which has an ESP32, Raspberry Pi, or Arduino, it’s easy to slap on a small LCD display or connect via WiFi to see what’s wrong. At least, that’… ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...
