FLASHING HEARTBEAT

Discover this interactive solder kit that reacts to your presence by flashing its red LEDs in a heartbeat sequence! This kit includes a heart-shaped PCB that will be able to stand on its own once you've finished assembling it. You will need to solder 24 red LEDs, along with lots of other components. Once finished, the heartbeat gadget will be able to detect your presence or any form of movement from a distance. How do you ask? It has an on-board infrared light and an infrared receiver. As long as the infrared receiver 'sees' the infrared light, the LEDs won't work. When the receiver can't 'see' the infrared light anymore, because something or someone has come in between, the LEDs will start to flash.
