Arduino Control LED with Fritzing

Posted by: mistan

Fritzinn and Arduino to control a bi-color LED with PWM

Download Fritzing executable Binary for your system (Arch 64 in my case)
Start Fritzing and design your wiring as shown (Breadboard Tab)
set up Arduino IDE path if needed in Fritzing preference
use firmata_test to check the wiring is working (upload StandardFirmata first)
go to Code view in Fritzing, input testing code, save, choose the correct Platform, Board, Port, and then Upload.

By uploading the sample code from here, you should see a fading in/out of bi-color led.
