1. An LED is connected to PORTB.5 of ATmega328microcontroller.
Write a C Program that toggles LED after 0.5 Seconds. Assume XTAL =16MHz.
To generate this delay use Timer 1 CTC (Clear Timer on Comparematch) mode
Programming.
2. Write a program to generate a square wave offrequency of 250 Hz with 50% duty
cycle on PORTB.5. Assume XTAL = 16MHz.
Use Timer 2 Normal Mode Programming.
3. Write a program using 16-bit timer to generate asquare wave of frequency 100Hz
with 70% duty cycle. Assume the crystal frequency is 16 MHz.
