WebArduino Timer Interrupts. Timer interrupts in Arduino pause the sequential execution of a program loop () function for a predefined number of seconds (timed intervals) to execute a different set of commands. After the set commands are executed, the program resumes again from the same position. The Arduino comes with three timers known as Timer0 ... WebArduino
