SONIC NKK611 Hedgehog Remote Controlled CAR, Multicolor

Product Information

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 can’t rotate due to insufficient power. 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. Effect: The RGB ambient light at the bottom of the Maqueen shows a variety of colors and presents a gradient effect. 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.

Effect: Detect the distance between the sensor and obstacle ahead, and display the data on the LED Matrix (unit: cm). 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. 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.Learning Target: Learn to read the distance of ultrasound, so that later can be flexible use of these data.

After installing a battery in the car, the motor still can’t be controlled to rotate by burning program while the power light is on?Effect: As the flashlight illuminates the LEDs on Maqueen, the vehicle starts to move forward. The brighter the light is, the faster Maqueen moves.
