Same as pcDuino v2, we can use an external infrared receiver that is connected to GPIO of pcDuino3 to receive the infrared signal. Moreover, pcDuino3 has built-in infrared receiver. There two infrared receivers need different drivers to operate.
Test the built-in infrared receiver:
After load the proper driver, type “$ sudo cat /proc/kmsg | grep “ir_code” ” at the terminal ,we can get the value of the key on the remote control being pressed:
Test external infrared receiver:
We connect the external infrared receiver to D8 pin of pcDuino3, then we load the proper driver.
When we press the key on the remote control, pcDuino3 will print the corresponding key value at the terminal.

Thanks for the demonstration, but it is flawed in a few ways.
Other than the pcDuino v3, you do not list any of the equipment you use in the demonstration. If the IR transmitter is not critical, it should be stated that any IR transmitter can be used, but it is still a good idea to give examples or sample part numbers.
You state, ” There two infrared receivers need different drivers to operate.” And then go on to say twice, ” load the proper driver”, but never specify what the “proper driver” is or where it can be found. A good tutorial does rely on “then magic occurred” steps.
The demonstration should restrict itself to the built-in IR receiver on the pcDuino v3.
