Topic: Potentiometer instead of restitors for LDR (Read 987 times) previous topic - next topic

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

the resistors are 4.7K
I am not sure about the LDRs, they are small :)

circuit attached

thanks, K

just realized, maybe I should have posted in an other subgroup [general electronics], however it's for music with SuperCollider. best, K
