I have a project where I would like to control a countdown clock using a remote with:

Arduino Uno R3 Development Board

Funduino Uno Protoshield Board

Freetronics Dot Matrix Display Connector

Arduino IR Reciever

Both the DMDCon and the IR use digital pin 11. Can these two share the pin 11 or is there a workaround of sorts?


The workaround would be to configure the https://github.com/shirriff/Arduino-IRremote library referenced in your question to any available digital input.

  • @Kerl Not all pins might be supported, see the documentation about supported pins. – Avamander Feb 29 '16 at 20:56
