Whadda Flashing Heart

This soldering kit reacts to your presence and makes the red LEDs blink in the rhythm of a heartbeat.

The heart-shaped circuit board consists of 24 red LEDs and many other components that need to be soldered onto the board. The finished kit can be placed on a table and detects your presence or any other form of movement from a distance of xx cm, thanks to the integrated infrared light and infrared receiver. As long as the IR receiver sees the IR light, the LEDs will not function. When the IR receiver no longer sees the IR light because an object or person blocks it, the LEDs start to blink.
