That looks more like an Elegoo Uno R3, not a Genuino/Arduino. I know its german but you can see pictures. I did exactly the same pin connection like in this tutorial: Serial.println( mySwitch.getReceivedProtocol() ) Serial.print( mySwitch.getReceivedBitlength() ) Serial.print( mySwitch.getReceivedValue() ) MySwitch.enableReceive(0) // Receiver on interrupt 0 => that is pin #2 Here is my code for the receiver part: #include I also used a tv remote but there is no output. I check its functionality by making output onto the serial monitor. I checked whether the module is broken by using another one but it doesnt work either. ![]() The transmitter is definately working because i can control a remote outlet. ![]() The arduino will use the receiver while the raspberry will use the transmitter. Im trying to make a raspberry and an arduino communicate over 433 mhz modules.
