FRIGO Alarm Open !!!!

Reminder: Close the fridge quietly... I don't want to get caught taking a drink every time, but I also don't want to leave the door open. Mounting this gadget is easy: First, you need to assemble it by forcing screws into the blanks to create threads. Next, connect the LEDs in parallel. To do this, cut the wires as short as possible and mark the anode (the larger stem). Then, connect the reed switch in series with the battery and one end of the LED anode. Attach the cathode to the other wire, leaving some slack for easy disassembly. To build it, you'll need: 1. 1 normally closed reed switch 1. 1 magnet 3. 3 blinking RGB LEDs 1. 1 18650 battery (3.7V) Wire and metal strip (4.5V battery recovery) 2 small VIS Tools needed: Soldering iron and solder Screwdriver Installation: Place the piece on the edge of the fridge with a double-sided sticker. Position the magnet close to the back to stop the flashing. That's it! It's been working for over a year now. I recharge the battery about every 6 months, especially when the light starts to fade. Other blinking LEDs can be used, but you'll need to test them first and add a resistor to limit the current according to the manufacturer's datasheet. A diagram is available to help explain this better.
