I am facing the same issue with my arduino uno using 4 IR sensors .even though i have created the four objects for them they are all sending the output when only one is supposed to receive the signal at a time . and even my arduino uno has its own ir transmitter along with the ir sensors so i am having trouble in running both at the same time. here is my code suggest me any improvement for 4 ir sensor data reading.
#include <IRremote.h>
