<p>MakeCode graphical programming: Drag-and-drop graphical programming, which is very interesting and easier to stimulate children's interest in programming and cultivate programming thinking.</p> <p>Support the use of the most left python programming language to train logical thinking skills and improve children's mathematical cognition;</p> <p>Select the tone and beat corresponding to the note through the program, compose the music, and through the buzzer; when a black line is detected, it uses a unique algorithm to automatically track and correct the direction. The distance between the car and the obstacle can be learned by using ultrasound ;</p> <p>The car is equipped with an infrared receiver, when the infrared remote control sends an instruction, the car immediately executes; write the expression code in the program and display it through the light;</p> <p>The infrared sensor of the trolley senses the desktop at all times during operation. When the trolley reaches the edge of the desktop, it will automatically stop running; the infrared sensor continuously detects when the trolley is running, and the trolley will automatically when it senses an obstacle in front.</p> <p>Programming software: web graphical web programming, Micro:Python programming terminal programming, Android mobile terminal programming</p> <p>Programming language: MakeCode\/MicroPython</p> <p>Sensors: RGB lights, RGB car lights, buzzers, line-following sensors, ultrasonic sensors, brightness sensors, acceleration sensors, electronic compass, LED5x5 dot </p> <p>Interface: RJ25 expandable sensor interface, UART serial port</p> <p>Control core: </p> <p>Control : infrared, Wifii or Bluetooth</p> <p>Power supply: 1 x 3.7V18650 lithium battery (not included)</p> <p>Battery life: about 2 hours</p> <p>type: XRmbit motherboard</p> <p>Product size: 190x125x105 mm</p> <p>colour: blue</p> <p>Material: metal</p> <p>Package Contents:</p> <p>1 x chassis</p> <p>1 x ultrasound</p> <p>1 x motherboard</p> <p>1 x TT motor</p> <p>1 x remote control</p> <p>1 x Infrared line tracking sensor</p> <p>1 x Bluetooth module</p> <p>1 x WIFI module</p> <p>1 x USB cable</p> <p>1 x screw</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
