Timer1 is halted and initialized to operate in "normal mode". The counter register in Timer1 is given its initial value. The timer's overflow flag is cleared. The overflow interrupt is enabled.

ICIE1 = Input Capture Interrupt Enable OCIE1B = Output Compare B Match Interrupt Enable OCIE1A = Output Compare A Match Interrupt Enable TOIE1 = Timer Overflow Interrupt Enable TIFR1 This register ...

Programming Arduino UNO Timers. In this tutorial we will use the TIMER OVERFLOW INTERRUPT and use it to blink the LED ON and OFF for certain duration by adjusting the preloader value (TCNT1) using ...

Hardware Interrupt: It happens when an external event occurs like an external interrupt pin changes its state from LOW to HIGH or HIGH to LOW. Software Interrupt: It happens according to the ...

The projects aims to setup a hardware timer that will generate an interrupt as a background function to run at regular intervals when working on microcontroller projects. Interrupts are signal that ...

The clock frequency is 16 MHZ, and the Timer interrupt 1 of the Arduino is configured to generate interrupts at every 0.5 seconds. Timer 1 prescaler is set to 256 and the timer counter is loaded to ...

All 4 LEDs are cleared to 0 at the beginning (i.e. all lights are OFF, or all relays are deactivated). The clock frequency is 16 MHZ, and the Timer interrupt 1 of the Arduino is configured to generate ...
