Features:
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 – the 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!
