I am currently trying to light up a 12V LED strip from the Arduino Mega 2560. I’m doing a home security system where the lights are turned on/off depending on the PIR sensor detects motion. The output voltage is 5V and the required is 12V. I was thinking of using an OP-AMP but was not sure if it would work or not and what kind should I use.
I also plan to use a 12V Rear Car camera to act as a surveillance of a mini home. I was wondering if this is a good idea or are there other modules that allow video recording?
