I am trying to phaseshift a 490 Hz signal from the D3 pin on the nano.
I have a phaseshift from the logic...but I don't know why I can't just read it on the scope...it reads 0V on that pin. (Allow me to point back to the whatsapp image I have attached in the original post.)
I tried the voltage divider circuit. It was overpowering the sensor so I had to skip it. That is OK. I am more concerned about the phase shift or rather being able to read the phase shift.
