Weevil LED Photoresistor Sensor Module Soldering Learning Kit DIY Kit for Starter Description: Once Weevil's eye is soldered, we can test the functionality of the board. Place the CR2032 battery in the battery holder, positive side up. If it is dark, you should see the LEDs light up. If not, cover the sensor with your finger to test it. If your its eyes don't light up, don't worry! Start with some simple problems. Check your solder joints to make sure your components have a good connection to your board. Solder should flow inside the board and do not bounce around the component pins. Also make sure your transistor and LEDs are correctly oriented.   Package Included: 1 * Weevil shape PCB 2 * Red LED 1 * 47k Ohm Resistor 1 * Photoresistor Sensor 1 * CR2032 cell Holder (battery not included) 1 * 2N3904 Transistor 2 * 220 Ohm Resistors
