To briefly explain the receiver code : Like the transmitter code we include the RC-Switch library and instantiate an RC-Switch object to give us access to all the RC-Switch methods. this should be called right after receiving data display the received data on the debug serial lineĭebug_Serial.println(mySwitch.getReceivedValue()) ĭebug_Serial.println(mySwitch.getReceivedBitlength()) turn on LED to show that data has been received enable the RC-Switch receiver pin and start checking for RF data enable the serial line used for debugging use the Leonardo's onboard LED to display data being received use Leonardo's Pin 3 to receive data on (Interrupt 0) Turn off led when transmission is completeĮxample code for an RF-Link 433MHz Receiver using the RC-Switch libraryįind the tutorial and Transmitter code here: Only the first 'length' bits of 'code' will be transmitted This is the data packet that will be transmitted Set the amount of times to re-transmit each data packet Set the desired pulse length in microseconds (Similar to baud rate) LED will be connected to physical pin 3 (Arduino Pin 4) Use ATtiny85 physical pin 5 to transmit (Arduino Pin 0) Use the RC-Switch Library to send data wirelessly between 2 micro-controllersįind the tutorial and Receiver code here:
