This program can realize the ultrasonic ranging function, and has functions such as LCD display, serial port output, and changing range.
The complete circuit diagram can be used directly for circuit design reference. Simple CNC DC power supply, core power circuit part. Including AC and DC input parts, the pre-voltage regulation part is helpful for dispersing the heat of power devices; input and output protection, startup delay, communication functions; voltage control, current control, overvoltage and overcurrent protection;
The source code is written by myself as a C program. The robot does not walk very smoothly and requires the joint efforts and improvement of robot enthusiasts.
Using the third-party cloud platform Gizwits, we created an IoT application system based on ultra-low power consumption Nuleo STM32 L073
It is a good learning material for students studying microcontrollers and smart cars.

Mini quadcopter flight control source code program, if you are interested, you can take a look.
Motor speed measurement (use Hall + magnet or infrared reflection tube + black and white code disk to do this experiment)
The smart car based on AT89C82 can realize ultrasonic obstacle avoidance, infrared obstacle avoidance, Bluetooth and infrared remote control car control and automatic tracking.
Proteus simulation example (8051)-stepper motor control.
Use sensortile to make a somatosensory one-handed drone remote control, which can control the flight of the drone in various postures. It uses ppm control during simulated flight and 2.4G control during actual flight. The file is an mdk project, the chip used is stm32l4, and it has been tested on the simulator.
It must be 10 points. This is the result of my three months. It is a program for competition. You can download it. If you don’t understand, you can ask.

This project, a voice-controlled dance robot, is designed after the human body structure and has 15 degrees of freedom (each leg has 4 degrees of freedom, each arm has 3 degrees of freedom, and the head has one degree of freedom), and uses MSP430 microcontroller Using the microcontroller as the main controller and the Lingyang 61 microcontroller as the auxiliary, it is possible to complete a set of smooth and beautiful Tai Chi movements, passionate and enthusiastic hip-hop movements and other dance movements under the control of voice commands.
This work is a thermometer based on face recognition. The appearance of the work is a temperature measuring gun. The work is mainly composed of the K210 kit provided by Sipeed, Hetai HT32F52352 chip, WIFI communication module, cloud server, IC card reader module and LDO power module. etc., the K210 is controlled by the HT32 chip to collect images in real time, and the collected images are processed locally. If there is facial information in the collected images, the facial features are extracted based on the face model, and then compared with the person in the image library. Compare the feature values of the face, and return the recognition results to the HT32 chip and the host computer for us to view the temperature measurement results. The following is a physical picture of the overall work and an introduction to its functions.
