I have following voltage divider in which I want to sink its voltage down to nearly 0 directly from arduino uno 5V GPIO. But I have few questions.
If I set pin mode to OUTPUT and pin to LOW, it will sink all the divided voltage(4.857v) and max current will be 1.2mA. Right ? but will that be problem to uC because R1 is pulled high by 12v.
Also if I set pin to HIGH, what would happen ?
