 Bigger Bigger  Smaller Smaller  Reset Reset

Hello,
 I wonder whether it is possible to use a pot instead of 6 resisors that are helping with LDRs.
Basically, I wouldn't like to change a software mapping every time the installation is in another room with differenent brightness (or light coming from a projector) and thought that if it is possible to swap the 6 resistors to 1 pot I then could adjust the resistance and have an easier life. Is this possible?

thanks and all the best, K

I don't think you connected the grounds, Dave.

"Helping"?
Can you draw a circuit?

I am not sure about the LDRs, they are small smiley
