Bluetooth/tracking/obstacle avoidance smart car

Overview

Using STC15W204S main control chip, it is low-cost and multi-functional. An external Bluetooth module is connected to achieve Bluetooth control. The circuit board has a built-in tracking/obstacle avoidance circuit. Install the infrared transmitter in front of the car and modify the code to achieve obstacle avoidance (both obstacle avoidance and tracking programs can be modified directly). Install in the same way. Below is the trace. There are still remaining IO ports that can be expanded to maximize the use of the chip. The battery uses two 18650 rechargeable batteries (about 7V), the Bluetooth module model is arbitrary (Bluetooth operation is very simple, long press to go, release to stop), the colored lights on both sides use WS2812 RGBLED, and the PWM speed is adjustable in two gears, acceleration and deceleration. ..... car pictures Bluetooth interface
