This lesson shows how you can output analog voltages on the Arduino microcontroller. On the arduino uno you can do analog writes on pins 3,5,6,9,10,11. These are the pins marked with the squiggly lines. You can get more supporting information including code and schematics at our WEB site http://www.toptechboy.com
I am Paul McWhorter from toptechboy.com and I will be putting together a series of tutorials on use of the Arduino microcontroller.
