Hello, this is our first post on the forum although we have browsed for a while..

We are currently producing a circuit that takes the values from LDRs on the circuit and maps them to different controls of a synthesiser (for example pitch, volume etc)

However in the initial stages we are having trouble with the readings from the LDR, we have set up 2 LDRs at the moment to test. On 1 of the LDRs, when the resistor is being covered the value increases, it is the opposite on the other.

Could anybody shed some light on this situation and how we could make both of the values coming from the LDRs read the same?


Thanks in advance  :)
