Moerman: Arduino: Luchtkwaliteitsmeter

LED en buzzer om snel de toestand te zien zonder kleine lettertjes op het display te hoeven lezen. De LED is groen bij schone lucht (instelbaar, standaard tot 2000 PPM CO2), oranje als het wat minder wordt (tot 4000 PPM), en rood als de lucht echt verfrist moet worden. Ook gaat'ie nu en dan piepen bij slechte lucht.
