... adding LDR to the pin, doesnt change any values.
I get the values around 250-300. adding LDR to the pin, doesnt change any values
It is needed to convert the change in resistance of the sensor into a change in voltage that can be measured.The analogue input can only measure voltages not resistances.
Is this rite?
Is it ok, if I give the the same supply to all these 6
