int potPin_blue = A2; //declare pin for the potentiometer for the blue LED

int readValue_red; //declare variable to store the read value from the potentiometer which controls the red LED
int readValue_green; //declare variable to store the read value from the potentiometer which controls the green LED

Managed to get the Arduino Motion Light Sensor to work!!! Although I really should be focusing on other things at the moment...
