Installing Your Battery and Testing
Insert the coin cell battery into the battery holder with the positive, labeled as (+), side facing up. Slide the switch to ON to see the LEDs light up. Remove the battery, and then continue to the Finishing Touches section.
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 project is switched on. Check your sewing for any loose threads or ends that may be touching other parts of your circuit and causing a short circuit. Learn more about troubleshooting your project in the LilyPad Basics: E-Sewing tutorial.
