This project demonstrates a simple LED flip-flop pattern using an Arduino Uno. The LEDs will toggle between different colors in a sequential pattern, creating a flip-flop effect. The circuit consists ...

The hardware is built around an Arduino One, a character LCD and a sensor made from a blue/white LED and a simple photo transitor (I do not have a datasheet but it seems to work well). Because of the ...

This is a very simple arduino project where a led is turned on by setting the pin 13 as output, then write it with a high value, in our case that means that pin 13 will deliver 5 volts. Advertisement ...

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. Anyone interested in creating interactive objects can “play” with Arduino! Described ...

The Circuit Scribe pen lets you draw smooth lines, which don’t require any drying time, with the ink fuss-free—it’s not smelly, messy or gloopy, like alternatives.

[Patrick] was prepping for some future projects he had in mind, for which he will need a simple 2D array of addressable LEDs. While it is certainly possible for him to build his own LED array and c… ...
