Bluetooth Serial Relay and push button.

Projects General Guidance
10

this is the actual code without the button.

i'm not really good at programing i need some examples so i can learn to add buttons that do the same as the serial commands.. example if serial reads A it turns off a relay, and if i press a button it turns off or on the same relay.

i'm planing to use this a light switch. so i can turn off and on switches.
