Grading scheme for lab 2

• AVR with flashing lights, demonstrating timing, as per the description, 2/10
• Quality and smoothness of PWM (Pulse Width Modulation) to get variable light output 2/10
• Cleverness and program organization, 2/10
• Answer random questions about this lab, 2/10
• Audible output of loud and quiet clicks, 1/10
• Adjustment of tempo using potentiometer on one of the analog inputs, 1/10

Note that you should easily be able to get 8/10, but the audio output and analog input will require additional thought and planning.

It is suggested that you begin by getting everything else done quickly to then allow sufficient time for the audio output and analog input.
