Jaycar Short Circuits Two – Red/Green LED Flasher Kit (555 Timer IC)

You've heard about the 555 Timer IC but you want to see it do something you can actually watch. This kit builds a red-and-green LED flasher that alternates like a police-car light. Solder it up, pop in a 9V battery, and you've got a working oscillator on your desk. It's the cleanest way to understand how a 555 Timer IC actually works. Add to cart and build it this weekend
