Arduino 433Mhz / IR Board
Das 433Mhz / IR Board habe ich mir zusammengebaut, um für die Versuche mit den Funksteckdosen und IR-Fernbedienungen nicht ständig alles auf dem Steckbrett zusammenstecken zu müssen. Das Modul ist komplett fertig mit 433Mhz Empfänger und Sender, sowie IR-Sender und -Empfänger. Der passende Quelltext dazu ermöglicht das Auslesen oder Senden bestimmter Codes.
Lochraster Layout
R1 = 33 Ohm
R2 = 1 kOhm
T1 = 2N2222
