Steuerung einer Funksteckdose (Grundlagen siehe RF Link) über eine TV Fernbedienung mit Hilfe von Arduino

Hardware

Arduino	Arduino Proto Shield	RF Link 434 MHz Sender	TSOP1738
Zusammengebaut

IR Codes auslesen

Zum Auslesen der IR Codes folgende Bibliothek verwenden: A Multi-Protocol Infrared Remote Library for the Arduino
Demoprogramm: IRrecvDump

Liefert bei einer Panasonic Fernbedienung folgende IR Codes:
