Overall your plan is ambitious but seems well thought of. In this plan, various things need to be monitored or controlled simultaneously, while the lcd keypad accepts inputs. You will need to write your code with state machine. It's extremely difficult for first timers. Plus you have your unique hardware so online forum members that don't have your hardware will be able to provide limited help.Is there a slightly less ambitious plan that involves less components to control and sense?
well it's been a few days and no one has been able to tell me anything new....anyone else?
