Hello!! I am using a switch which is connected to arduino uno's interrupt 1(digital pin 3), and using Ken shirrifs IR library for IR signal Transmission.according to IRremote library i connected IR led to digital pin 3. But problem is that in when i pressed the switch instead of generating the int…

IR led and Interrupt 1 cause reset arduino uno.

Do you have a transistor driving the LED and does it have a seriese resistor?
