The emergence of simple robots can be said to be a result of the educational sector’s vigorous promotion of robotics technology. In the field of children’s education, assembling their own robots is very appealing to children, and the process of exploration is far more meaningful than the final result—practice is the mobilization and verification of … Read more
Building a DIY robot is a dream for many, but unfortunately, most people are non-professionals, and some have never encountered similar knowledge before. What should you do? Should you give up on your dream? Recently, a detailed article on How to DIY a Robot was published on WikiHow, explaining the entire process of building a … Read more
Recently, a robot made independently by an 18-year-old high school student has gone viral. It can help carry bags, track objects both indoors and outdoors, and even follow in the dark without any issues; it can even be used as a ride. From principle determination, shape design, circuit connection, to code writing, the entire process … Read more
1. Design Concept: Initially, power is supplied to the microcontroller via a manual key. The power indicator LED4 lights up, indicating that the microcontroller is running, and Relay 2 works to power the microcontroller. The working time of Relay 2 is set via a button, allowing the system to automatically cut off power. The working … Read more
1. Design Concept: Initially, power is supplied to the microcontroller via a manual switch. The power indicator LED4 lights up, indicating that the microcontroller is running and relay 2 is activated to supply power to the microcontroller. By pressing the button, the working time of relay 2 can be set to achieve automatic power-off, and … Read more
Q: How can I receive such great articles for free every day? A: Just click on the above “51 Microcontroller Learning Network” to follow for free! My bedside fan’s mechanical timer is broken, so I designed a simple timer controller using the 51 microcontroller. The program has been initially debugged on the experimental board, and … Read more
