With this Bit, you can control your circuits with motion. The motion trigger is similar to the sensor on an automatic door: when someone is moving nearby, it sends an ON signal to the following Bits. It's very sensitive, so don't move a muscle unless you want to be detected! Try it with some LEDs to create a security light.
If you're looking to track your collection or decide on your next bit, this list is a good place to start. Fill in the number of each bit you already own to get started. You can also see what bits are included in the most popular kits including Gadgets & Gizmos, Rule Your Room and the Synth Kit. Tip: try the grouping feature to change the view to group items by their inclusion in a kit. Fun fact: it costs $1,289.63 (US Dollars) to buy one of every bit on this list.
