Hey Guys,
I have a circuit using an arduino that controls 8 leds and a CD4066, its for an fx box that has 8 programs. The LEDs are just to display which program is selected and are controlled directly by the arduino
When building the test circuit on the breadboard all was working fine. although I do seem to have misplaced the sketch and so had to write it again.
Only led 1 and 8 leds will light (basically, either end of the pot)
I'm getting a good 4.99V across the the pot,
I've checked and double checked the pin connections and continuity tested the led's to the arduino pins and all good there.
I've tried several pots, but these are all brand new 10k lin pots, checking the resistance on a multimeter checks out and the resistance changes smoothly when measuring and moving.
Using the serial monitor, I am reading from around 0-40 something, then, a huge deadzone for half the distance of the pot then for the last quarter of a turn reads from something like 1000-1023.
I'm fairly sure nothing is wrong with the code, I'm worrying that its something wrong i did on the PCB,
any ideas?
