Hello Team,
I've broken down the code to the bare bones to hopefully get some insight on this.
Below you can see that when I don't measure the analog input, that my digitalRead inputs are reporting a LOW variable when the switch position is off:
When I turn the switch to the right position, then the digitalRead for the right indicator input responds correctly:
Similarly when I turn the switch to the left position, then the digitalRead for the left indicator input responds correctly:
Now, when I put the analogRead statement back into play and I upload it to the board, then I get a HIGH on the digital read input for the right indicator input without the switch being turned on:
The left indicator still responds as expected when I turn the switch on:
Now, when I remove my board from my circuit board, then the digitalRead for the right indicator input reads correctly again:
So this kind of leads me to a board problem, however, I've checked all my hardware to see whether I have any short circuits between my analog input and my digital input but there are none. I also rechecked (multiple times) that there are no short circuits between 5V and the digitalRead input pin and there is not.
When not measuring the analog input, then I measure 0 volt from the right indicator digital input to ground when it is not turned on and this is expected. But as soon as I declare the analogRead statement, then I measure the 5 V available on the 5V pin on the right indicator digital input.
At this point in time I don't know what is left from right lol. I've attached the schematic diagram I put together in case someone might be able to pick something up there.

Looking forward to potential feedback.
