Based on the Lichuang Liangshan School - "Patch the numbers together" smart car

Overview

1. The car is divided into three parts as a whole: (1) The core board based on Lichuang Liangshangpai (the MCU is the domestically produced GD32F45ZGT6) (both the empty board and the core board are made of immersion gold technology, good reviews!).
(2) 100cmX35cm The tracking board is equipped with 5 channels of infrared tracking (the rheostat is recommended to be replaced ) (
3) 100cm The trace screen printing is inconsistent with the screen printing of the base plate (TR03, TR04, and TR05 are messed up. When designing the tracking board, TR05 was placed in the middle for convenience, but it does not actually affect the use) 2. The power supply circuit is L7805CV from STMicroelectronics 3. Battery The dual-section 18650 (7.4V) used is 4. The DC motor driver chip is L9110SM/TR 5. The available resources on the base plate are: (1) Two buttons and four LED lights, which can be used for button display and direction display. (2) A buzzer, which can be used to simulate whistle and music (3) A 2.4G module, which can be used for remote control (4) An infrared remote control receiver (5) An ultrasonic module 6, the car's lighting is located in the tracking On the board, it is connected to the PC9 and PD5 pins on the core board to simulate the switch of the car light. 7. Main function part of ultrasonic detection and infrared tracking (most of the codes refer to the information of Lichuang smart car) motor steering part 8. Unverified function (2.4G remote control) 9. Due to the epidemic, when I got the components, they were already It’s the 20th, so not all functions have been verified, and will be updated when completed! (The car in the video can run very fast. Since it is difficult to adjust the infrared tracking module again when it is placed on the ground, the function is verified on the table and the speed is adjusted slowly)
