In the hot summer, the air-conditioned house watermelon is matched. I have organized 10 Need for Smart Cars. While playing a smart car while waiting for the summer, it will improve your skills.
1, the best smart speed WiFi and Android control car (original works original)
This Needs Speed uses STM32F401 (STM 32F401 Data Manual) chip as the main control chip, divided into PC client and smart cells. Connect the router to set the LAN system via the WM3612-WiFi module, the PC client obtains the current location of the smart car through the wireless, according to this information, according to this information, the wireless mode is used to issue control information, remotely operated the car; the Android mobile phone on the smart car is connected to this LAN, Use the camera to collect the video information and send it to the PC client. The smart train makes a corresponding action according to the control information sent by the PC client, and the movement, left and right turn, stop and other actions.

2, gesture remote control smart cars have been introduced, is your trolley upgrade?
Geituring remote control car score is divided into a truck drive circuit and gesture control circuit. The Bluetooth master connection between the carrier drive circuit and the gesture control circuit is different, please pay attention to distinguish. The SET feet and 3V3 feet in the drive circuit are short, and the hand-controlled portion does not need to be short. Sensor-sensor module for gesture remote control is applied to the ADXL345, ADXL345 is a small and thin low-power 3-axis accelerometer with high resolution (13 bits), and the measurement range is ± 16g. Digital output data is 16-bit binary complement format, which can be accessed via SPI (3 wire or 4 line) or I2C digital interface.

3, voice remote smart car
(1) Start the car operation command "big white" (refer to the superior land team).
(2) Send an instruction "advancement", the car will walk forward, the LED is in the state of running the horse, and the obstacle will automatically park. At this time, the "forward" instruction is invalid, and the trolley issues a warning and flash.
(3) Send an instruction "back", the car will walk back, the LED is in the state of running the horse, and the detection obstacle is invalid.
(4) Send an instruction "left turn", the cart will move a distance to the left and then stop, the LED light is in the flash state, and the impairment will issue a warning and all lights flash.
(5) Send an instruction "right turn", the trolley will move a distance from the right and then stop, the other row of the LED is in the state of flashing, and the impairment will issue a warning and all lights flash.

5, STM32 single-chip smart sweeping smart car robot lithium battery charging 73- (PCB + source + circuit diagram + paper)
This system consists of STM32F103C8T6 microcontroller core plate, 2-way infrared avoidance module, 2-way button, fan driver, motor drive, boost module, lithium battery charging module, and battery pack.
1. After pressing the startup button, the train starts, at the same time, the fan rotates the dust; after pressing the stop button, the train stops rotating, while the fan stops rotating.
2. In the operation, the infrared avoidance sensor module on the left detects an obstacle, then turn right; the infrared avoidance sensor module on the right is detected that there is an obstacle, then turn left; if any side is infrared The bumpering sensor module detects an obstacle for a certain period of time (the trolley may not walk), then the car is retired and then rotated.

9, wireless remote control smart car based on STM32F401 (original)
The system adopts STM32F401 as the master chip of the handle, STM32F103 as the main control chip of the carrier. The cart is powered by a L298N drive motor, the FuBata-S3003 servo, and is equipped with a DHT11 digital temperature humidity sensor to collect temperature and humidity data, and then transmit temperature and humidity data to the handle via the NRF24L01 wireless communication module, and the handle receives the data after mini 12864 liquid crystal. The temperature and humidity are displayed. The handle uses a button and gravity sensing to control the movement of the car to control the needs and services of different types of users.
