Looking for a fun and easy way to add a bit more interaction to your LED-laden projects? Why not turn them into proximity sensing LEDs?
Our hacker, [Will], is just getting into designing his own PCBs. He was looking for a simple project to try out that wouldn’t be too hard to design and manufacture a PCB for, so he came up with this clever little interactive LED array.
It’s actually a very simple circuit which also makes it super easy to build on a prototyping breadboard. Each proximity sensing LED is made up of five components. Three resistors, an … Read the rest
