Matrix Keypad routine

[Kalind]

thats my point. I have no idea where to begin...i was thinking maybe scan keypad first, check if A or B was pressed and if so then act upon it by prompting the user to enter a desired setpoint. once that's done, press ok and return to the main display screen. the alarm can be set on for the desired lower setpoint and once the upper setpoint has been reached, the relay should switch on. vice versa

Then write some code and see how it works!
If it doesn't work, post the code, and I'm sure somebody will help you figure it out.

The first thing to do is open Mr. E's Keypad.bas and read the instructions he wrote for you.
