Thanks marco_c, what I want to do is something very specific and that is: turn on 1 of 16 LEDs depending on which of 16 sensors and pressed. So when the program starts ALL LEDS are off i.e. writtten LOW, when one of the sensors are turned on (by Touch) a corresponding LED is written HIGH, when the senors are OFF the corresponding LEDs are off. So there are only two values. 0 or 1. One is LED on and the other is LED off. So IYHO this snippet is sufficient to accomplish is objective?
