Done wiring and powered up, send the above two codes to MICROBIT. You can get the same distance data. And you should see the distance data on the LED matrix of micro:bit. Or you can open the serial monitor of Arduino IDE to get the data. Shown as below. This LED module is of high brightness because the lamp beads it carries is 3w. You can apply this module to Arduino or other projects, ideal for Robot or search and rescue application. For example, intelligent robots can use this module for illumination purpose. The rotation angle of servo is controlled by regulating the duty cycle of the PWM(Pulse-Width Modulation) signal. The standard cycle of the PWM signal is fixed at 20ms (50 Hz), and the pulse width is distributed between 1ms-1.5ms. The pulse width corresponds to the rotation angle ( 0°～90°). A photoresistor or light-dependent resistor (LDR) or photocell is a light-controlled variable resistor. Its principal is very simple. The module is based on a touch detection IC. This module allows you to remove the troubles of conventional push-type buttons. It has low power consumption and wide working voltage.

It is the simplest sound making module. You can use High/Low level to drive it. Changing the frequency it buzzes can produce different sounds. Insert the micro:bit into keyestudio micro:bit sensor V2 shield. Then connect the analog alcohol module to keyestudio micro:bit sensor shield. Connect VCC to V1 header, ground to ground, A0 pin to P0 header. 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 programIf you slap the table where the sensor locates, when the vibration sensor detects the vibration signal, an LED on the Piranha LED module will lights up, otherwise, LED off. Insert the micro:bit into keyestudio micro:bit sensor V2 shield.Then connect traffic light module to micro:bit sensor shield, separately connect R, Y,G pin to S2, S1,S0 pin header, GND pin to ground. Shown below. BBC micro:bit V2 board – available in 4 colours red, yellow, green & blue (please note you cannot select the colour of the micro:bit you will receive) Power the sensor shield with DC 7-9V, and this shield can power the micro:bit and other sensor modules, pretty convenient.

Insert the micro:bit into keyestudio micro:bit sensor V2 shield.Then connect magnetic sensor to micro:bit sensor shield, connect S pin to S0 pin header, + pin to V1 header, - pin to ground. Shown below. 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". In the above project 8, we have done a button control experiment. This time, we are going to replace the button switch with a capacitive touch sensor. In this project, you will learn how to use keyestudio touch sensor to control 5*5 LED of micro:bit show different images.

When design the circuit, sometimes you will need to test whether an object is tilted left or right, so in this case you can use our tilt sensor. In this project, you will learn how to use our digital tilt sensor to control 5*5 LED of micro:bit display different images.

Inputs and outputs are an important part of any computer system. As a very small computer, the BBC micro:bit has plenty of inputs and outputs to learn about and use with electrical components 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.Buzzers can be categorized as active and passive ones. The difference between the two is that an active buzzer has a built-in oscillating source, so it will generate a sound when electrified. The buzzer on this module is an active buzzer. Done wiring and powered up, send the code to MICROBIT. When the spring plate of crash sensor is pressed, the buzzer module will beep, otherwise buzzer will not sound. Insert the micro:bit into keyestudio micro:bit sensor V2 shield.Then connect touch sensor to micro:bit sensor shield, connect S pin to S0 pin header, + pin to V1 header, - pin to ground. Shown below. So in this project, you will learn how to use a flame sensor and an active buzzer module to simulate the fire alarm system. Please Note: BBC micro:bit is NOT included. You can buy the Kitronik Inventor's Kit with the BBC micro:bit already included here.

To get you off to a flying start, we have included an easy-to-follow tutorial book which guides you through everything you will need to know about programming the BBC micro:bit. You don't need any experience with programming as the tutorial book will guide you every step of the way. In life, we can use the display and other sensors to do a variety of experiments. You can DIY a variety of small items. For example, use a temperature module and display to make a temperature tester, or use an ultrasound module and display to make a distance tester. Insert the micro:bit into keyestudio micro:bit sensor V2 shield.Then connect the photocell module to keyestudio micro:bit sensor shield. Shown as below diagram. In the previous project 23, we only get the analog value of temperature in the current environment. Now, we are going to use a LM35 linear temperature sensor to detect the ambient temperature. Finally get the specific temperature value of current ambient via calculating, and display it on the micro:bit LED matrix or on the Arduino monitor.You should see the value is showed on the LED matrix of micro:bit. Or you can open the serial monitor of Arduino IDE to get the value like this: This flame sensor can be used to detect fire or other light sources with wavelength stands at 760nm ~ 1100nm. Its detection angle is about 60°. You can rotate the potentiometer on the sensor to control its sensitivity. Adjust the potentiometer to make the LED at the critical point between on and off state. The sensitivity is the best.
