**This library supports only one IR receiver and one IR sender object (IRrecv and IRsend) per CPU.**<br/>

However since sending is a serial task, you can use `setSendPin()` to switch the pin to send, thus emulating multiple sender.<br/>

The receiver uses a special **timer** triggered function, which reads the digital IR signal value from one pin every 50 &micro;s.<br/>
