20 LED light string using Charlieplexing and Arduino

by admin on 13/12/2011

Another project I have been working on lately is a LED string made out of 20 LEDs which are charlieplexed. This way we can control all 20 LEDs separately with the Arduino though only using 5 pins. The string will be made out of a LAN cable. Lan cables are cheap and provide 8 wires. And some shielding.

This project will be uploaded to Instructables and will be in our study association’s magazine called “ProtoType”
