I recently bought an IR Camera for my Raspberry Pi, something like this:
The only problem with the camera is the temperature of the IR leds which get way to high over time. Because I need these leds only one or two times in an hour I want to turn off those leds. My idea is to use a transistor which is switched by an gpio pin of a raspberry pi. But since I'm an amateur in using transistor I don't know which transistor and resistors to use. Any help?
The leds are powered by the camera with 3,3V and I measured about 0,28A at full brightness per led.
