Many students are puzzled when controlling motors, as the microcontroller pins can output high and low levels. Why can’t we connect the motor directly to make it turn? Why is a driver necessary? What is its purpose? There are so many different driver models. Is it possible to operate without one? Today, let’s discuss this. … Read more
The interrupt system and timer/counter of a microcontroller are core modules for implementing real-time tasks and multitasking. 1. Interrupt System 1. Basic Concepts Interrupt: When a specific event (interrupt source) occurs, the CPU pauses the current task and executes the Interrupt Service Routine (ISR). After completion, it resumes the original task. Function: Improves CPU efficiency, … Read more
1. Control Requirements1. Start/Stop Control: A light touch on the “Start/Stop” button allows for flexible switching of the motor’s operational state. Each time this button is pressed, the motor accurately toggles between running and stopping states, making operation simple and efficient;2. Direction Control: The “Forward/Reverse” button allows for easy changes in motor direction. Each press … Read more

This is like a “mini clone” of Python, … Read more
In this article, we will briefly compare the PWM output capabilities of Arduino and ESP32, and then use both to drive the same electronic speed controller (ESC). 1. PWM Output Function of Arduino In Arduino, we can use the analogWrite() function to output PWM signals. This function has two parameters: pin and duty cycle (0-255). … Read more
Written by｜Bomb Dance Everything started from an occasional thought in 2004 Earlier, I came across an interview with Bruno Putzeys, one of the founders of Mola Mola, in SoundStage! Ultra from 2014, which detailed the Mola Mola DAC that had not yet been officially launched at that time. Bruno mentioned that everything should start from … Read more
