Problem using IRremote library I am using arduino pro micro 5v 16Mhz. I have built a simple IR transmitter circuit as shown. 

The code i am using is 
https://github.com/z3t0/Arduino-IRremote/blob/master/examples/IRsendDemo/IRsendDemo.ino

Although this worked yesterday, it doesn't seem to work now. I was able to turn on and off my TV yesterday but the led is not even blinking now. I checked led, its working. 

After hours of trying to make it work I tried different library. 
https://github.com/cyborg5/IRLib2/blob/master/IRLib2/examples/send/send.ino

Surprisingly this seems to work but the code is a bit complicated for receiver. 

I want to use the first library. Any help is appreciated. Thank you.
The problem was with timer timer settings in library. I checked different timer configurations with different pins and its working now. I found out that timer4 uses pin 13 which is not used in Pro Micro board so I am now using timer 3.
