Step 5: Finish
Attach a wire to the pair of tweezers using tape, glue, or solder. Poke a small hole in the top corner of your board and thread the end of this wire underneath. Connect it to the negative lead of the battery, and you should be in business! Touch the tweezers to the metal sides of the holes and the light should light up and the buzzer should ring. If not, you might want to check your connections and make sure everything is connected in the correct direction.
