DIKAVS Beginner Learn to Solder Fun Kit: Weevil Eye (Pack of 2/set)

Description

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! 1 x WeevilEye PCB 2 x Red LEDs 1 x 47k Ohm Resistor 1 x Miniature Photocell 1 x 20mm Coin Cell Battery Holder 1 x 2N3904 Transistor 2 x 220 Ohm Resistors
