WEEK 10: Output Devices

Individual assignment: add an output device to a microcontroller board you've designed, and program it to do somethi ng

For this week's assisgnment I selected to create a speaker. I found a previous student's project site and tried to reproduce their design. The design was based off of Niel's board with the addition of an LED light and button.

I ended up not being able to find out what 'T1N' in Neil's board design. I was told by a TA that it's 'NDS355AN N-channel MOSFET'. I ended up finding and using the component with the TA's approval.

The Schematic

I use Eagle to create the schematic and output the traces.

The Trace
I had gotten a couple of errors in the processes of routing the and ended going back and forth a couple of times between the trace and the schematic.
