Before finalizing the assembly, it's a good idea to test the components to ensure the circuit is working before we close it up.

Test Trinket

Plug in a JST male connection from a charged Lithium Polymer battery to the female JST connector that was soldered on the Trinket. If the LED power on, that means it works and is ready for NeoPixel power!

Test PowerBoost + Switch

Connect the battery to the JST connector on the Powerboost 500C. Flip the slide switch and see if it the blue LED powers on.

Test NeoPixel Strip

Grab the NeoPixel Strip and Trinket. Ensure you have code loaded onto the Trinket. Connect the 3 male jumpers from the NeoPixel strip to the female jumpers on the Trinket. GND to GND, PWR to +Bat and DIN to #0. Power the Trinket on with USB or battery and check to see if the LED's power on.

Test NeoPixel Rings

Connect the 3 female jumper cables of the neopixel ring to the 3 male jumper cables on the Trinket. GND to GND and PWR to +Bat and DIN to #0. Power the Trinket on with USB or battery and check to see if the LED's power on.
