Hi All, I've come across a strange behaviour when I set pinMode by an array. The setup: Arduino Nano 10x LEDs wired individually (from ground, through resistors) to pins 2 to 11. The wiper of a 10k pot wired to A7 (i.e. 0-5v input). The code progressively lights up the LEDs as the pot is turned …

[image] serious_sam: pinMode(A7, INPUT); This is your problem. Remove this line. DO NOT USE pinMode() ON PINS USED ONLY FOR analogRead(). Pins A6 and A7 are outside the range of digital pins so using pinMode() on them indexes off the end of two tables in the firmware. Pin A7 is accident…

So you think I have a hardware problem maybe ?
