I believe you can find its principle in it; you just need to prepare it according to the list of items I listed, and you can make a mini washing machine of your own!

In our daily life, we often see excavators working on construction sites. The large excavators work very flexibly, making a great contribution to the construction of our cities. So can we use the tools around us to make an excavator? The answer is yes, using ELECFREAKS micro:bit Nezha 48 IN 1 Inventor's Kit, you can do it.

Nucleic acid testing has long been a part of our daily life as the epidemic has become normal. So can we make a simple nucleic acid sampling machine with simple equipment? Let's take a look at my work.

Hands are one of our most important and mostly used parts in daliy life, there are many artworks coming from the idea of simulating hands because of its skillful characteristic and good appearance, this blog also simulates the hands.

In life, sometimes there will be no electricity. At this time, if there is a small electric light, it will be much more convenient. Today, I will tell you how to make a simple small electric light.

The four-way survey sensor is a new sensor in the Planetary family. It has four survey probes and has survey capability on more complex maps. The operating voltage is between 5-3V.

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 .
