As a perfect example, these LED “blinking eyes” were created by ... Thanks to the pseudorandom number generator in the Arduino code, the “eyes” even have a bit of variability to them ...

If you're looking for a fun electronics project to give a small fright to trick-or-treaters you can create a spooky blinking ... LED eyeballs, an ATtiny85 microcontroller, and an Arduino.

In this article I will add some simple Arduino LED projects starting with basic ones like how to turn on an LED, blinking, and more. Every step will have the code, the schematic, photos of the project ...

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 ...
