With the risc of sounding stupid, here goes:
I have a tiny camera (like the arducam boards) with an IR-cut filter. It is activated through an LDR.
I want to bypass this and switch it with an arduino (3.3v).
The IR-cut filter has a small connector with a red and black wire. After some probing it turns out when you put +3.3v on the red, and 0v (ground) on the black, the IR-cut switches one way. When you put 0v on red and 3.3 on black it switches back. it uses tiny amounts of miliamps, it is an inductive load.
Can i set one gpio to a low output, another gpio to a high state and have a current path ? then switch the high to low, then the low to high and have the current path reversed ?
I love programming but am not that knowledged in electronics, so henche i figures i better ask first
