Step 5: Test Your Circuit
Insert your coin cell battery with the positive side facing up (marked with a +), into your battery holder. The battery slides in the opening only one way (the side opposite of the on/off switch). Turn on the switch to see if your LED shines bright!
Troubleshooting
With any electronics project there are times you will have to troubleshoot if your circuit isn't working. If your circuit isn't lighting up, try a new battery or check that your switch is in the on position. Check your sewing for any loose threads or ends that may be touching other parts of your circuit and causing a short circuit. See the picture for examples of conductive thread short circuits –- practice tidy stitching to keep your thread from causing problems.
