Proud Father moment: daughter built her first electronics project! A variable speed, flashing LED circuit using a 555 timer! She could even explain how it worked! Nice way to start off a week of vacation!
http://rookieelectronics.com/wp-content/uploads/2012/07/Flashing-LED.jpg You can buy the parts at Orion electronics or KW Surplus!It's pretty easy actually! 1 or 2 resistors. 555 chip. 1 Capacitor. A bunch of short wires and an led (or if you'd rather hear a sound, a buzzer/beeper!) Here's the circuit diagram for exact values of items!
