Hi Folks,
I found some code that works to transmit the required signal to an RX-2B RC receiver, the code works great from my Uno but when I tried to run it from my Yún nothing happens.
The code has definitely uploaded as I tested with an LED and the pin is getting a HIGH voltage written to it.
Does anyone have any idea what the issue might be? Code below.
Thanks.

* Many cheap RC toys are based on TX2 / RX2 transmitter / receiver ICs.
* This Arduino sketch allows to replace the TX2 based Remote Control with Arduino.
* Just one single pin is used from the Arduino board.
*
* Connect Arduino pin 10 to the solder point where the toy antenna is connected or to the toy antenna cable.
* One can replace pin 10 with other free digital pin available on the Arduino board.
