Step 7Test Your Circuit
Before you solder, make sure your circuit works. If it doesn't, you'll know there's a mistake somewhere or you need to check your connections.
To test, simply touch the ends of the battery pack (with a resistor) to the correct colors at any point on the circuit. The resistor is necessary to make sure you don't blow the circuit with too much power. You can simply twist tie the resistor onto the positive end of the battery pack and then touch the appropriate colors with the resistor and the negative end of the battery pack.
If your lights all light up and they are not dim, you can move on to the next step. If some or all don't light up, make sure you wired correctly and check to make sure all of your wires are touching where they should be. Keep trying to fix until you let there be light.
