Stap 4: Nu de toevoeging van LCD met arduino
* LCD RS pin naar digitale pin 12
* LCD inschakelen pin naar digitale pin 11
* LCD D4 pin naar digitale pin 5
* LCD D5 pin naar digitale pin 4
* LCD D6 pin naar digitale pin 3
* LCD D7 pin naar digitale pin 2
* LCD R/W pen op grond
* 10K Ohm weerstand:
* eindigt aan + 5V en ground
* wisser naar LCD VO pin (pin 3)
