Hello,
This is my First time here so go easy on me
Im Trying to complete a program for my Arduino that allows me to manage my pumps. The program is pretty much where I want it to be, It currently runs a 16x2 LCD and displays system modes selected by a push button!
I wanted to add the ability to use a rotary encoder to slide through the modes rather than using a button. Ive got my code to see the encoder and print out its digital state over serial but no matter what i try im unable to get the High of the encoder to trigger my push button (pin7)
I think i may be going about it the wrong way trying to use the encoders state to trigger a pin rather than telling the Arduino that a change of state in the encoder means trigger the next (if loop)
I look forward to any information you could help me with
Please feel free to use my program if its any use to you!
