Description
Wearing headphones, I can't hear my door bell ringing. So I made a simple optical door bell with a led strobe and some electronic parts.
Pictures will explain it.
Parts I used:
1 BASETech Strobelight LED 12V
1 Kemo B042 Time switch
1 HF33F Relais
1 Socket for power connection
Some wires
