Last week we built beautiful Christmas tree lights. You can reprogram, and reuse these all year round. But what's cooler than beautiful Christmas tree lights? How about Christmas tree lights that change based on what's happening around the tree? Adding light sensors to your tree lights should take between half an hour and an hour from start to finish.
This year we made our own Christmas tree lights. They're really easy to build, and can be reprogrammed to be used all year round. Use our handy guide to make your own!
Sometimes you want things to only happen when the world around you changes. In electronics, we use sensors to detect these changes. In this post we're going to look at a couple of sensors, how they work and we'll show you how to use one with your HIDIOT.
