About this deal
Effect: The ultrasonic sensor constantly detect the distance between the Maqueen and obstacle ahead, if it is smaller then 30cm, Maqueen randomly turns left or right to avoid the obstacle. A constraint condition should be added for test barrier, that is, filter out the data when the distance is not 0 or less than 5. You can also add 100-millisecond delay to prevent multiple reflections. Line patrol, ambient light, LED lights, ultrasonic interface, servo interface, buzzer, I2C interface, mechanical expansion screw hole, etc. ... full-featured, highly expandable.

The brighter the light is, the faster Maqueen moves. Upload error? For uploading to the device, you need to switch the code window to the "Auto Generate" window.Learning Target: Learn to read the distance of ultrasound, so that later can be flexible use of these data. Thanks to the easy-to-use pistol-like ๐ฎ.๐ฐ๐๐๐ญ ๐ฅ๐๐๐๐ข ๐ฅ๐๐ ๐ข๐ง๐ ๐๐ข๐ก๐ง๐ฅ๐ข๐๐๐๐ฅ, with 2 speed modes (๐๐ข๐ช ๐ฆ๐ฃ๐๐๐ for learning and smaller areas and ๐๐๐๐ ๐ฆ๐ฃ๐๐๐ for racing and larger areas,) our fast rc cars for kids and adults can be easily controlled within a range up to 250 feet After installing a battery in the car, the motor still canโt be controlled to rotate by burning program while the power light is on? Effect: The RGB ambient light at the bottom of the Maqueen shows a variety of colors and presents a gradient effect. The key assignments in the following table are in hexadecimal. In this product, we read the last two digits of the key assignments and automatically convert them to decimal data.
Learning Target: Learn to read the key assignments of infrared, so that later can be flexible use of these data.Programming Method: Makecode graphical programming, Mind graphical programming (based on Scratch 3.0) Effect: Detect the distance between the sensor and obstacle ahead, and display the data on the LED Matrix (unit: cm).
Effect: Press any key on the IR remote controller, the key value that corresponds to the pressed key will be displayed on the LED matrix (show the last two digits of key value in decimal). This book is composed of 20 teaching cases, including some classic games like Catching Apple, Cat and Mouse, etc, and projects related to life scenes like Obstacle Avoidance Maqueen, Research and Rescue Maqueen. Each case is designed based on teaching practices. It aims to inspire all children to participate in programming and pave the path for them to further develop and create.
This book provides a cost-efficient and fun way for primary and secondary school students to learn programming. The courses guide them to explore how to control a robot car Maqueen by coding, during which they will get to know the basics of robotics. Maqueen is a mini robot car intensively designed for STEAM education, small but powerful. It is developed based on the popular micro:bit board. Children can code Maqueen to play, learn and create so as to enhance their analytical and creative thinking skills, which is precisely what the original intention of STEAM education is. Effect: The left and right LEDs flash alternately at an interval of 0.5 second. Meanwhile, the buzzer makes two different tones with the flashing frequency.
Perhaps the battery is dead, and it is recommended to replace it with a fully charged one. When the battery voltage is lower than 2V, the LED on the board and other functions can work normally, but the motor canโt rotate due to insufficient power.
