Overview
BPI:Bit MoonCar(Web:bit MoonCar), developed by Webduino and iCShop,made by BPI, is a self-propelled car specially designed for the BPI:Bit(Web:bit)/Micro:bit development board. It has built-in tracking function, color sensing, infrared emission and reception, and buttons. Combined with Web:Bit, it can let the dot matrix display patterns of various colors.The foot position of ultrasonic wave is reserved in front, which can realize the function of automatic obstacle avoidance.More fun ways to control yourself through the Web:Bit education!
Hardware
power source
MoonCar comes with two tiny metal motors and a training wheel, which are of better quality and durability than the motors with plastic gearboxes. The training wheels are specially made of non-metallic materials, which can reduce the noise caused by striking the ground.
Sending and receiving messages
The front of the MoonCar is equipped with a pair of infrared emission and reception, through the general infrared remote control to its instructions. Infrared transmitters can send messages to communicate with other mooncars, making it much more playable.
buzzer (make a sound)
On the right side of the MoonCar is a passive buzzer that can be programmed to produce different sounds, such as an electronic organ or an alarm or a ringtone. I can edit the statements generated by different notes and pauses to make MoonCar sound like talking.
Magic lantern
MoonCar is surrounded by a total of eight RGB LED lights, which are WS2812 and can be programmed to easily control the LED you want to light or adjust its brightness. Is there any color you want in the preset column? You can mix the colors you want by adjusting the proportions of R, G, and B channels.
Linear sensor (Track the line running)
At the bottom of the MoonCar is a linear sensor that can move along black or white lines by reflecting infrared light. One on the left and the other on the right can detect the out-of-bounds direction of movement on the black line.
Color identification
In addition to the linear sensor at the bottom, there is a color sensor, and a white light supplement light lamp. During the process, the color blocks on the ground can be identified, and the colors can be directly displayed with the magic LED, which greatly improves the fun.
