Add 9 LED’S to the board and 3 resistors.
The resistors value depend on the color of the LED:
| Color | R-value |
| Green | 47 |
| Red | 270 |
| Yellow/Orange | 270 |
| Blue | 2k ( or 2k1 ) |
| White | 2k7 |
LED’s to be used: 2x5x7mm rectangler.
Mounting tool
I designed a mounting tool to help you align the LED’s to the PCB.
