Interface BUZZER with STM32
This setup will provide a frequency of (45000000/255*692) = 255 Hz and we can vary the duty cycle to observe the changes in the sound of the buzzer.
RGB led and STM32
Basically each colour have a range of intensity from 0 to 255 which depends on the voltage provided to the respective pin. We combine these intensities (0 to 255) of these three colours to produce 16 million (256x256x256) different colours.Basically each colour have a range of intensity from 0 to 255 which depends on the voltage provided to the respective pin.

Servo motor with STM32
Servo motors use feedback to determine the position of the shaft, you can control that position very precisely. As a result, servo motors are used to control the position of objects, rotate objects, move legs, arms or hands of robots, move sensors etc. with high precision.
PWM (Pulse Width Mod) in STM32
Pulse Width Modulation is one of the important functions of timer. PWM is a technique to control analogue circuits with digital output from microcontroller.
As you all know that an Analogue signal is the one whose value varies continuously with time whereas digital signals can only be either high or low.
