Hi everyone, today I will teach you how to make a steering car with our micro:bit Wonder Building Kit, the principle is very simple, mainly using the rack and pinion steering gear and the unstable structure of the parallelogram.

Sonar:bit is a 3-wire ultrasonic module with the working voltage between 3-5V. It is available to be used to 3.3V or 5V micro-controller system. With only one 3-wire(GVS) cable, it can work properly. Compared to the normal 4-wire ultrasonic module, it has saved one IO port. The measurement range of sonar:bit is 4cm-400cm. It can output stable and accurate measurement data with ±1cm tolerance only.

Temperature and humidity sensor is a module based on DHT11 digital temperature and humidity sensing element. It is sensitive to the ambient temperature and humidity changes and can be used for temperature alarm, humidity testing and other works.Now let's use it to measure the temperature and humidity of the surrounding environment.

Micro:bit is becoming more and more popular in many countries ,it’s easy to learn for young kids ,also is easy to teach for teachers ,but only one micro:bit for learning how to programming is not enough ,so for the markets there are many micro:bit breakout board and kits for micro:bit ,but it’s hard to know which kits are best or don’t know how to choose it . Many of our clients also ask us same questions ,Elecfrekas has all kinds of micro:bit accessories ,but they don’t have know how choose them . Although micro:bit is focus on the primary and secondary schools ( age for 7-16),but for older students also can use the micro:bit to do many interesting projects .There let me show you how to choose our micro:bit kits .

WS2812 rainbow lamp is a very commonly used electronic material by makers. Its colorful luminous characteristic is deeply loved by everyone, but they are sold mostly in bare PCBA in the market. The beads without any obstruction gives out dazzling light to us. Thus, I will make a rainbow light panel with a soft light.

This article is from a novice who used 2 micro:bit motherboards, 2 Nezha expansion boxes, and 4 rainbow lights from planet X sensor series to make eyes and hearts for cute Christmas characters. And she makes the beautiful but dull Christmas KET board dazzling.

This blog introduces how to get the Nezha Breakout board and the PlanetX sensors working with KidsIoT, here we’ve made a project called the micro:bit remote feeder, which makes it possible to feed your pets at home or offices at any time.

At the same time, we’d like to bring you with our KidsIoT from a simple IoT project.

Hi, today let’s make a cool breathing light effect to the chassis of the Cutebot. Breathing light means that the light changes gradually from bright to dark under the control of a microcomputer, and it feels like a person is breathing. We can achieve the effect of breathing light through simple programming.

Hi, in this project we will use the microbit to make a system that can remotely monitor the light value and remotely control the lights in the home. Its principle is very simple, we only need to connect the microbit to WiFi and upload the light value in the room to the KidsIot platform, we can remotely monitor the light value in the home through the KidsIot platform, and use the remote control button in the KidsIot to control the light switch in our home.

Following with the version of the Aircrafts Battle, I’d like to add more challenges to on the basis of the former version with the bullets updated with a “BOSS” this time.
