Light dependent Resistor about Resistor


I have doubt about the connection of resistance. In this why can’t we use less or more than the 10kohms resistor. This is the only doubt until I learned.


Hi @vr905900,

The use of the resister kept in series with the LDR is dependent on what the internal resistance of the LDR is.

For the LDR that we supply with the Bolt kit the required resistance is 10kOhm.
