9/29 pcb design:
design, produce, and program a PCB with a microcontroller
For this assignment, I learned about CharliePlexing LEDs and created a "waterfall" flexible circuit on acrylic.
Since I modified the hello.echo.44 board, the hello.echo.44 program was the first program I loaded onto the board to verify that it works. The results of my work are displayed below. The process of making the PCB board is documented here.
This is the circuit that I designed (CAD file):
My waterfall circuit:
Note: Although I secured the MTA adaptors to the board with hot glue, I also an adaptor board so that the circuit would not be damaged during programming and power cycles (CAD file).
