Write the Arduino code (only the void loop() routine) to read the analog voltage applied

to pin A2 and compare it with the value of the voltage applied to pin A6. The code should call

the subroutine TurnOn() if the voltage on A2 is less than the voltage on A6 or call the

subroutine TurnOff() if the voltage on A2 is larger 1.5 times the voltage on A6
