Insert the micro:bit into keyestudio micro:bit sensor V2 shield. Then connect the micro servo to the shield. Connect the signal line to P3 of micro:bit, power line to V1 header, ground line to ground header. In this project, you will learn how to use a vibration sensor and micro:bit to control an LED on and off. In daily life, we often need to implement the function of counting and speed measurement. How to achieve these functions? You can easily match photo-interrupter module with microcontroller via code debugging. In this lesson, we connect a keyestudio photo-interrupter module to micro:bit sensor shield, then control 5*5 LED of micro:bit show different images. After mastering the basic information of BBC micro:bit, in the following part let’s move on to programming projects. Use this small board with keyestudio micro bit sensor shield and other sensor modules to make some interactive experiments. Play it and learn it. Enjoy your wonderful time! The Arduino folder contains both the Arduino program itself and the drivers that allow the Arduino to be connected to your computer by a USB cable. Before we launch the Arduino software, you are going to install the USB drivers.

In the previous projects, you have learned various external information detected by different sensors, such as temperature, light, sound, gas, and so on. Now, let’s use the keyestudio thin-film pressure sensor and micro:bit to detect external stress. Show the analog value of pressure on the micro:bit LED matrix or on the serial monitor. In the following, we will use keyestudio 1602 I2C module as the display, connect it to I2C pin headers of micro:bit shield. You will learn how to control the 1602 LCD show the character“keyestudio”and number. Insert the micro:bit into keyestudio micro:bit sensor V2 shield.Then separately connect the buzzer and flame sensor to keyestudio micro:bit sensor shield. Shown as below diagram. In this project, you will learn how to use a PIR motion sensor and micro:bit to detect whether there is someone move nearby. Finally show the different images on 25 LED matrix of micro:bit. This project is very simple. You can use only a micro:bit main board and a USB cable to display the “Hello World!”. It is a communication experiment between the micro:bit and PC. This is an entry experiment for you to enter the programming world of micro bit.

The BBC micro:bit is the spiritual successor of the BBC Micro of the 1980s, which itself introduced a generation of children to computing. The BBC micro:bit carries on this decades 30-year tradition and does it 18 times faster and it's also 70 times smaller than its predecessor.

Done wiring and powered up, send the code to MICROBIT. When sensor detects an object ahead, its signal terminal will output a Low level, and LED matrix on the micro:bit will show the number 0. Or else show the number 1. Insert the micro:bit into keyestudio micro:bit sensor V2 shield. Then connect the TEMT6000 light sensor to keyestudio micro:bit sensor shield. Connect the signal pin to P0 header, +pin to V1 header, ground to ground. Insert the micro:bit into keyestudio micro:bit sensor V2 shield.Then connect obstacle detector sensor to micro:bit sensor shield, connect Out pin to S0 pin header, + pin to V1 header, GND pin to ground. Shown below. Done wiring and powered up, send the code to MICROBIT. When touch the sensing area of sensor, you should see the LED matrix of micro:bit show the icon like a heart. Or else, it will show the icon like this. For those DIY smart cars, they often have a function of automatic obstacle avoidance. In the DIY process, we need a servo to control the ultrasonic module to rotate left and right, and then to detect the distance between car and obstacles, so as to control the car to avoid obstacles.

This TEMT6000 light sensor is mainly composed of a high visible photosensitive light (NPN type) triode. It can capture the tiny light changes and magnify it about 100 times, which is easily recognized by the microcontroller for AD conversion.

Insert the micro:bit into keyestudio micro:bit sensor V2 shield.Then connect 3W LED module to micro:bit sensor shield, connect the S pin to S pin header, + pin to V1 header, - pin to ground header. One is to directly control the High and Low level input of micro:bit P0 end, set two square waves to control the buzzer sound. The other is to use the software's own function, input the square waves of different frequencies and different lengths on the P0 end. Finally make the buzzer module play the song "Ode to Joy". An LED, or light-emitting diode is an output device that gives off light. Your BBC micro:bit V2 has a display of 25 LEDs for you to programTap the capacitive button as an input for your projects - stop/start music, start a timer, run a program or whatever you decide! Powered on, the module requires the stable time about 0.5sec, at the moment all functions are banned to conduct self-calibration, do not touch the key, the calibration cycle is about 4.0sec. Then you can directly enter the https://makecode.microbit.org/ to edit your project program. Below is an example code we have done for you.

It has two signal pins, Analog A0 and Digital D0. The higher the alcohol concentration, the higher the A0 value. Insert the micro:bit into keyestudio micro:bit sensor V2 shield. Then connect the analog gas sensor to keyestudio micro:bit sensor shield. Connect VCC to V1 header, ground to ground, A0 pin to P0 header.If the soil is detected enough humid, the microcontroller will control the relay off, NO terminal disconnected, power off, so the pump will stop watering. Done wiring and powered up, send the code to MICROBIT. When sensor detects the movement of someone nearby, 25 LED matrix of micro:bit will show the icon like a heart. Or else, it will show the icon like this.
