Project guide

Switch Wiring

Slide Switch Wires

We'll need to make two wired connections to connect the switch to the Feather.

Solder Slide Switch

Wire up a small 2-wire cable to the middle pin and either one of the pins on either side.

Wired Slide Switch

Double check the solder joints to ensure they're solid.

Wire Switch to BLE Feather

We’ll wire up a the slide switch to the ground and enable pins on the back of the board.

Hot Glue Switch

You can use a bit of hot glue to secure the switch to the PCB. We can also use hot glue to insulate the exposed pins.

Power Switch

This allows us to turn off the 3-volt regulator and still recharge a LiPo battery over USB.

Connect Battery

The battery plugs into the port on the side of the feather.

Test Circuit

With the code and libraries uploaded, we can plug in the NeoPixel strip and test out the circuit.
