I have a photoresistor that basically will output between 0 and 1V and I connected it to a microphone jack. Now I wanted to know the value of that voltage.
It doesn't need to be very precise, all I need is to distinguish between shadow and sun. Also, it doesn't need to be continuously, it's only for a short period from time to time.
Using, for instance, the daqscope, i can't see the dc signal, i can only see waves if I move in front of the photoresistor quickly.
Can anyone help me??
