Stap 4: Zet het allemaal samen (afwerking YAY!)
We moeten dus uiteindelijk uploaden van de laatste schets. Deze schets zal verlenen de spanning van de TMP36 naar graden Celsius, het afdrukken naar de seriële Monitor en vervolgens opslaan als een variabele en stuur het naar de if verklaringen. Zij controleren welke categorie de temperatuur valt in en vervolgens licht van het juiste aantal LEDs. U kunt altijd het aantal graden van de LED-nummer wijzigt. De code wordt elke 4 seconden vernieuwd. Dus hier is de code en ik hoop dat je genoten hebt van dit Instructable!
