PWM on atmega8 via Arduino IDE?

Question

Arduino

For a simple project, you need to smoothly blink the light tape. Smooth ignition and extinction.
As the cheapest option, I chose atmega8 (dip 28). It was stated that there are 3 pwm (shim) channels available.
Arduino UNO acted as a programmer.
In test cases via Arduino as ISP, everything works only as digitalWrite() logical 0 or 1.
analogWrite() did not work on any of the examples.
The generator took an internal one at 1 MHz.

Answer 1

read about timers in avr, for example, on easyelectronics.ru and play it yourself.
