Velleman WSL213 Intermittent Heart

Description

This interactive welding kit reacts to your presence and makes red LEDs flash like a heartbeat. The heart-shaped printed circuit board has a tabletop stand. You will have to solder the 24 LEDs and the other components. The welding kit detects your presence or any form of movement from a distance of xx cm thanks to the built-in light and IR receiver. As long as the IR receiver 'sees' infrared light, the LEDs will not work. When the IR receiver can no longer see the IR light, because something or someone blocks it, the LEDs will start flashing.
