Prop-Maker Lightsaber

Wiring Buttons

The RGB LED push button will be connected to the Prop-Maker FeatherWing. To make assembly more efficient, we suggest using JST-PH connectors – These allow quick connections of components. Pre-made cables are available and linked the overview page. The RGB LED buttons require a total of six wired connections, so a 4-pin and 2-pin JST connector can be used. We suggest using a wire length of 62mm (2.4in) for each connection.

The second button is extra and does not serve any functionality.

Silicone Cover Stranded Wire

Pre-made JST cables are convenient but making durable connections can be achieved using silicone cover stranded wire. This 28AWG ribbon cable is really nice wire that is flexible and won't easily break. Using this wire and a JST-PH connector kit, you can create custom JST-PH cables.

JST-PH Cables

Take a moment to plan which wires you'd like to use for the buttons. Colored heat shrink tubing can be used to differentiate the connections. Each wire is about 62mm in length (124mm / 4.8in total length).

Solder Wires to RGB LED Button

Pins of the RGB LED button are labeled on the bottom of the plastic body. Reference these labels to match the wires with the RGB LED pins on the Prop-Maker FeatherWing. The polarity will need to match.

Solder Wires to Pushbutton

A 16mm panel mounted button doesn't require matching polarity, so this can be soldered to which ever pin. These can connect to an available GPIO pin on the Prop-Maker FeatherWing.

Red button does not need to be wired. It's available as an extra if you want to write code to make it do something :)

Wired Buttons

Double check the wiring to ensure the buttons have solid connections. Now is a good time to check the wire lengths and trim any excess. The tips of the wires can be tinned with a bit of solder to make attaching them to the pins easier.

Switch Wire

To make assembly more efficient, the switch wire is soldered to the bottom of the Prop-Maker FeatherWing. Reference the labels and solder a 2-pin JST cable to the SWITCH and GND pins.

RGB LED Button Wire

Reference the RGB labels and solder a 4-pin JST cable to the Red, Green, Blue, and V+ pins on the FeatherWIng.

Extra Button

If you plan to write the second button, use an available digital pin, NOT the IRQ pin (it's used for the accelerometer to talk to the Feather M4).
