Week 11: Output devices.

Assignment: "Add an output device to a microcontroller board you've designed and program it to do something."

Approach for this week:

1. Build an H-bridge board, following Neil's example in hello.H-bridge.44

Here are my files board, schematic.

Features of this board.



2. Problems and lessons.


3. Programming, using input signals, and results of PWMing.

Simple PWM in Arduino program:

Above the circuit, below the scope trace for a one-second on pulse.

Use of input signals.




4. Motor thoughts related to final project.


5. Notes from class 11/20
