Parts List
After I finished a working prototype I created an Arduino shield.
| 27 | LEDs | generic (I used 3 different kinds - 9 of yellow, orange, and red - all have a voltage drop around 2.0V) |
| 9 | Resistor | value depends on LEDs (I used 330Ω orangeorangebrowngold) |
| 1 | PCB | Eagle files are in the larsi-org/LED_Editor GitHub repository |
