uhhh... if you knew what an LDR (Light Dependant Resistor) was you wouldn't ask this
The point of these resistors is that there is no static value, but a variating resistor value...

You mean the one that is attached to the sensor?
I think its a 1.62Kohm resistor, at least thats whats on the parts list for the 50? robot

any resistor will work . . . but there is an optimal value that gives your robot the best sensor readings. the resistor value I gave is close to that value.
