Powering LilyPad LED Projects
One of the most commonly asked questions when getting started with e-textiles is “How many LEDs can I put in my project?” In this guide, we will cover conductive thread’s resistance and how that affects powering LEDs, calculations to predict battery and power requirements, and some construction tips.
