IR Scanner

Hier zeige ich euch einen einfachen IR Scanner.
Zum Video geht es Hier.

Benötigen tut ihr nur einen Arduino, sowie ein IR Empfänger. In meinem Fall ist ein Arduino Uno und ein IR Empfänger für 36kHz.

Anschluss Arduino <> IR

8 +5V
9 GND
10 Daten

Es gibt eine neuere Version der IRremote Bibliothek. Wie ihr die einsetzen könnt, zeige ich euch in diesem Video.
