Intelligent following car based on CI1122 module

1. Introduction to project functions

A small car that can follow you when barked perfectly solves the problem of wanting to keep a dog but finding that you don’t have time to do so. Of course, it can also be played as an ordinary smart car.

4. Hardware part

The main control part uses STC15W408AS and CI1122 modules, which facilitates rapid development and enhances later scalability.

The sensing part uses infrared tubes of different wavelengths to solve the problem of positioning the user, avoiding the problem of using expensive ultrasonic modules and microcontrollers that are not fast enough to measure the speed of light.

Comes with 1s battery protection part to avoid the danger caused by battery over-discharge and accidental short circuit of the motherboard

5. Software part

The infrared following part is planned to be completed in the future

This is the first time I have used a microcontroller to complete a complete design program. I wrote it quite randomly. Please forgive me.

Since the messages and logs that come with the CI1122 module cannot be closed, a violent serial port "protocol" is used to realize communication between the module and the microcontroller - that is, sending a large amount of the same data repeatedly

The motor and steering gear drive use the three-way hardware PWM that comes with STC15W408AS, which reduces the need for main control performance.
