For this week assignment: add an output device to a microcontroller board and program it to do something I decide to make the example of the DC motor and the LED array with the Charlieplexing principle.

DC MOTOR: I will start milling and stuffing the DC motor board to make the circuit before programming it:

DC motor board parts before stuffing

DC motor board components

I connect the external battery and the AVR programmer to the board to proceed with the program loading into the board:

LED ARRAY: Time for milling and stuffing the LED array board to make the circuit before programming it... this board has a lot of components!

I connect the external battery and the AVR programmer to the board to proceed with the program loading into the board:

At the beginning I have some problems when programming the board. The computer seems that is having problems finding the AVR programmer:
