It's turn on of hardware fast PWM in ATmega16 uses 2 controlling buttons with checking led.

• 1st button - increase duty cycle
• 2nd button - decrease duty cycle
• led (PORTC) for work checking of fast PWM.

Basic structure of fast PWM mode on ATmega16 for begginers. Don't forget to use datasheet!

0. You can use another MCUs. All you need is datasheet. Don't forget change pins!
1. Make project in AVR Studio choosing 8-bit MCU ATmega16.
2. Copy code from pwm_check_led.c into your main.c file.
3. Build project.
