Once the Weevil Eye is soldered, we can test the board’s functionality.
• Put the 20mm coin cell battery into the battery holder, positive
side up.
• If it’s dark, you should see the LEDs light up. If not, cover the sensor
with your finger to test.
• If your Weevil’s eyes aren’t lighting up, don’t worry! Start with some
simple troubleshooting. Check your solder joints to make sure your
components have a good connection to your board – solder should
flow into the board and not ball up around the component’s pins. Also
check to make sure your transistor and LEDs are correctly oriented!
