Step-by-Step Guide to Simulating a Stepper Motor Based on the 51 Microcontroller Using Proteus (Part 1) - ULN2003 Driver

This article introduces the Proteus simulation system for a 5-wire 4-phase stepper motor driven by ULN2003. The system implements forward and reverse rotation, speed adjustment, and single-step testing functions through button control. It details the structural characteristics (5 leads/4 phase windings) and operating modes (single-phase, double-phase, eight-phase) of the 5-wire 4-phase stepper motor, as well … Read more

Focusing on Embodied Intelligence: Hanwei Technology's Multidimensional Sensor Layout Leading the Evolution of Robotics

Recently, at the National Games, the humanoid robot serving as the “No. 0” torchbearer amazed the audience with its steady steps. Each of these seemingly effortless steps is rooted in a precise and powerful perception system. Countless sensors act like the “nerve endings” of the machine, conducting an unceasing flow of data and decision-making in … Read more

Starting from Chip Design: Success is the Mother of Success

by

As the saying goes, failure is the mother of success. However, in reality, it is often true that success is the mother of success. Chip design is a “high investment, high risk, high return“ industry. Firstly, the development cycle of chip design is often long. Even for the simplest LNA or switch, from project initiation … Read more
