Very simple ”alarm” if you forget to close the freezer door. Only a blinking light and no audio.
Very little soldering and easy to make but you need to get on of those small blinking lights that you put on your self (or your pet) to be more visible in the night. They are very cheap.
You also need a switch. I used one with a lever but a simple switch from an old mouse probably works.
Function:
The plastic cover constantly press the device “on button” so as soon as the switch is activated the led start flashing.
