If you are installing the optional lighting for the neck of the guitar, follow the wiring below.
Feather and NeoPixel Wires
Get the Feather, NeoPixel strip, slide switch and wires ready. Use the following wire lengths.
Wire Lengths
- 3-pin JST cable – 70mm
- 3-wire ribbon cable – 74mm
- 2-wire ribbon cable – 65mm
Count, Cut and Unsheathe
This project is using a Mini Skinny NeoPixel strip with 144 pixels per meter. The NeoPixel LED strip will be hot glued to the head of the guitar. The following NeoPixel strip was used in this project.
- Mini Skinny NeoPixel Strip (144/m) – 35 NeoPixels
Tin 3-pin JST Cable
Use wire strippers to remove insulation from the tips of each wire. Tin the exposed wire using a bit of solder.
Tin 3-wire ribbon cable
Use wire strippers to remove insulation from the tips of each wire. Tin the exposed wire using a bit of solder.
Strip 3-pin JST cable solder
Solder the 3-pin JST cable to the NeoPixel strip. Check and find the first NeoPixel in the strip. Solder white wire to data In, red wire to 5V and black wire to ground. Add pieces of heat shrink tubing before soldering connections.
Feather 3-wire ribbon cable solder
Solder the 3-wire ribbon cable to the pins on the Feather. Follow the cable and match up the colored wires from the 3-pin jST cable. White wire to Pin 5, black wire to ground and red wire to 3V.
Solder Slide Switch Ribbon Cable
Solder a 2-wire ribbon cable to the slide switch. Use the middle pin and either pin on the side. Add pieces of heat shrink tubing before making wired connections.
Test Circuit
Connect a 500mAh battery to the JST battery port on the Feather. This project uses the CircuitPython NeoPixel demo code. Use the slide switch to turn the circuit on and off.
