I am doing a project based on arduino environment. For now I need to write a code to light the LED when the IR Rx module doesn't detect any signals from the Tx module. Here i am using a can bus shield to transmit and receive the data and IR Tx/ Rx modules. I am having a problem on programming the arduino board to communicate with the sensors via can bus shield. Can anyone please give me some basic codes to initiate the program like defining the can bus and how to send the IR Tx signals and how to Receive the IR Rx signals?????
