Rotary encoder's "switch" pin connected to pin 8;
non-latching relay's "signal" pin connected to pin 25;
A switch is connected to the "always on" port of the relay and then connected to the solenoid for manual control of the solenoid (solenoid switch);
I have a piece of software that, to keep things brief, does something specific once the "push button/ switch" of the rotary encoder is pressed. However, if I press the solenoid switch, the software somehow registers that as a button press of the rotary encoder.
This is indeed really strange, given that the solenoid has no direct input lines into the Arduino. What could possibly cause this?
Can I provide any other info?
Thank you again.
