- Once the Weevil Eye is soldered, we can test the board's functionality
- Put the 20mm coin cell b attery 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!
