Design and Implementation of a DC Motor Control Simulation System Based on Microcontroller

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

Microcontroller: Choosing Between DAC and PWM for Audio Output? Test Data Reveals the Answer!

Hello everyone, I am Xiao Chen. Today, let’s discuss a practical topic: how can microcontrollers output audio signals? Currently, there are two mainstream solutions: directly using a DAC (Digital-to-Analog Converter) or using PWM (Pulse Width Modulation) for analog output. Both methods have their pros and cons, and many beginners can easily get confused. Today, I … Read more
