Hi everyone, I am using a color sensor that has a square signal which varies on frequency as an output. The duty cycle is allways 50%, the freq is the only thing that changes. I need to read two frequency values: 440kHz and 540kHz. I have read a lot of posts but I have not found a solution. So far…

Why make things so complicated?
