Overview

AA battery link https://m.tb.cn/h.U9mz2iG?tk=uqSddfWICct
battery box https://m.tb.cn/h.U9NaGAY?tk=ehDmdfWsJUi
motor is N20 reduction motor, model is six V , 1000 rpm
motor drive adopts changing PWM duty cycle to adjust the speed, so the motor drive chip RZ7899 is used
to realize obstacle avoidance and Bluetooth remote control functions. Since there is no venue for tracking, it cannot be debugged temporarily.
Please note that LED The silk screen and circuit are opposite, please follow the PCB welding process.
In the official program, you need to add a switch after the car light and buzzer to use the case statement. The port definition of the left light is wrong. After modification, it can be normal. On, use the Bluetooth serial port APP to send characters
