im fairly new to arduino but i want to jump in at the deep end and want to create a program that when an rfid come into contact with the correct key it turns a green led on. if the led is on an a button is pressed i want it to turn another led on and for every time its pressed after this i want it to turn a different led on for 5 seconds. i want it to do this even if the rfid key isnt present. to turn everythgin off i want you to have to remove the rfid key and hold a button for 5 seconds. i can invision it in my head but its hard to write it down so sorry if its not that clear. id prefer to learn how to do it than for someone to just write the code for me i just dont have a clue where to start.
