Guide for a DIY Arduino powered shift light with code and CAD files for housing.
Parts list is as follows;
Arduino nano
70mm x 30mm double sided Prototype PCB
1x 330 ohm resistor
1x 47 kohm resistor
1x 10 kohm resistor
1x 5v reg #7805
1x heatsink #V4330N (fits perfectly to the board and voltage reg)
1x PNP transistor #2N3906
1x 1000uF (min 6v) capacitor
2x neopixel 8LED strips #WS2812
The circuit needs to be built as pictured;
It should be assembled on the prototype board as pictured;
The circuit board can be connected to the car by splicing into the wires behind the OBD connector:
