Installing Arduino Software
When you get the UNO development board, first you should install the Arduino software and driver.
We usually use the Windows software Arduino 1.5.6 version. You can download it from the link below:
https://www.arduino.cc/en/Main/OldSoftwareReleases#1.5.x
Or you can browse the ARDUINO website to download the latest version from this link, https://www.arduino.cc, pop up the following interface.
Then click the SOFTWARE on the browse bar, you will have two options ONLINE TOOLS and DOWNLOADS.
Click DOWNLOADS, it will appear the latest software version of ARDUINO 1.8.5 shown as below.
In this software page, on the right side you can see the version of development software for different operating systems. ARDUINO has a powerful compatibility. You should download the software that is compatible with the operating system of your computer.
We will take WINDOWS system as an example here. There are also two options under Windows system, one is installed version, the other is non-installed version.
For simple installed version, first click Windows Installer, you will get the following page.
This way you just need to click JUST DOWNLOAD, then click the downloaded file to install it.

The buzzer used on this module is a passive buzzer. A passive buzzer does not have such a source, so DC signal cannot drive it beep. Instead, you need to use square waves whose frequency is between 2K and 5K to drive it. Different frequencies produce different sounds. You can use micro:bit to code the melody of a song, quite fun and simple.

Component Introduction
Line Tracking Sensor:
The tracking sensor is actually an infrared sensor, which can detect a black line. The component used in the sensor is TCRT5000 infrared tube.
Its working principle is to use the different reflectivity of infrared light to the color, then convert the strength of the reflected signal into a current signal.
When sensor detects a black line, the infrared rays are not emitted or the intensity of emitted ray back are not sufficiently strong, so that the sensor’s signal terminal outputs a High level. Otherwise, output a Low level.
In this way, we can judge the detected color by High or Low level of the sensor’s signal terminal.
Note: on the module, you can rotate the potentiometer to make the LED between on and off state. The sensitivity is the best.

Component Required
- Micro:bit main board*1
- Keyestudio Micro bit Sensor V2 Shield*1
- USB Cable*1
- keyestudio Obstacle Detector Sensor*1
- Dupont jumper wire*3
Component Introduction
Obstacle Avoidance Sensor:
The infrared obstacle detector sensor is actually a distance-adjustable obstacle avoidance sensor.
It has a pair of infrared transmitting and receiving tubes. The transmitter emits an infrared ray of a certain frequency. When the detection direction encounters an obstacle (reflecting surface), the infrared rays are reflected back, and receiving tube will receive it. At this time, the signal terminal will output Low level.
If no obstacle detected, the infrared ray emitted is weakened by the distance it travels and eventually disappears, so receiving tube cannot receive it and signal end of sensor will output High level.
In this case, it can judge whether there is an obstacle ahead or not.
You can rotate the potentiometer knob on the sensor to adjust the detection distance. The effective distance is 2-40cm and working voltage is 3.3V-5V.
Module features are as follows
- Working voltage: DC 3.3V-5V
- Working current: ≥20mA
- Working temperature: －10℃ to＋50℃
- IO Interface: 4Pin interface (-/+/S/EN)

Connect It Up
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.
Note: for obstacle sensor, you can rotate the two potentiometers on the sensor to adjust its sensitivity. Rotate the potentiometer near the infrared transmitter tube clockwise to the end, and then adjust the potentiometer near the infrared receiver. Sled light is turned off and keeps the critical point to be lit. The sensing distance is the longest.
The effective distance of the sensor is within 2-40 cm.
