Hello,
I am trying to replace a on/off push-button with a photocell. With the push button my device works as follow; when the button is pressed the device is ON and when the button is released the device is OFF. To replace this button with a photocell I need to have the following specs. When the light is on the device is OFF when the light the off the device is ON. I tired a photocells with different resistances such as 15K-30K --- 1M-1.5M but no of them worked. When I connect the photocell it immediately shots the circuit. I think the sepcs need to be 0K to 1M+. But I was unable to find such a photocell.
If some electronic engineer can tell me what can I do to solve the problem using the photocells I already have, that would be great. Or maybe you know where I can find a photocell with 0K it would be even better.
I am sure you might have some questions so please ask and I will give you all of the information that will help to solve my problem.
