//This code is when a character is inputted from the keyboard it does the
//sequence.
//When the push button is pressed it switches everything off, debounce code is applied aswell.
can anyone help as i can't seem to get the push button to switch off the lights and vibration motor, when i use the keyboard to input the character 'a' it switches it on i am really puzzled.
