Combine tutorial 7 and 8. Tutorial 7 uses the relay as a switch between two LED options. When the switch changes the LED, write a comment on the LCD screen that says what the user should see in the LEDs. For example, say “Green LED on, Red LED off”. Basically, whatever is happening with the LEDs should be printed on the screen.
