Control PWM with Arduino in 5 Minutes

Many MCU manufacturers can complete PWM control through internal registers, such as Arduino, STM32, etc. This integration greatly simplifies the development process, allowing you to create applications with PWM in just 5 minutes, such as breathing lights, servo, buzzer control, etc., refer to the video below↓↓↓

3 PWM Control Application Experiments
In the video, the Seeeduino development board uses the ATmega328P, which has a total of 3 timers/counters:TC0, TC1, TC2, corresponding to different ports and PWM frequencies:
1) The frequency of TC0 PWM square wave is 980Hz, corresponding to digital IO:Output ports 5 and 6;
2) The frequency of TC1 PWM square wave is 490Hz, corresponding to digital IO:Output ports 9 and 10;
3) The frequency of TC2 PWM square wave is 490Hz, corresponding to digital IO:Output ports 3 and 11;
This means that PWM waves can be generated on ports 3, 5, 6, 9, 10, and 11.
In programming, it involves:TCCRx (control register), TCNTx (count value register), OCRx (output compare register), etc.To simplify, these registers are preset internally!Of course, if you have the ability, you can modify them yourself!
In the video, the ATmega328P code can be obtained by replying PWM on WeChat to “Darwen Says”.
