This is one individual littleBits bit: The pulse Bit is like an electonic heartbeat. It sends out a stream of short ON signals, and you can make the speed of the pulses faster or slower using the included screwdriver. It's great for making LEDs blink! What's littleBits? littleBits is an opensource library of electronic modules that snap together with magnets for prototyping, learning and fun.
