The first circuit in the Inventor’s Guide is a simple one that turns on and off a single LED repeatedly. I used:
- 1 x Arduino Duemilanove
- 1 x breadboard
- 1 x 5mm Yellow LED
- 1 x 330 ohm resistor
- 3 x wires (1 each for gnd, 5v and pin 13)
This was a good introductory circuit to cut my teeth with correctly wiring the parts together, as well as uploading the C program to the Arduino from the IDE.
