As we all know, ELECFREAKS recently developed a development board based on RP2040--Pico:ed. Compared with the official Pico, this board is more suitable for classroom use. It is similar to micro:bit's gold finger edge connector and is also compatible with all micro:bit kits developed by ELECFREAKS.

Often, without our eyes and ears, our hands and feet are not as accurate as they could be, because we get feedback through our eyes and ears. Our brain can use the feedback to constantly correct the movement of our hands and feet, creating closed-loop feedback. If we need to use PWM to precisely control the brightness of an LED, we need feedback, but the brightness of the LED is an analogue signal.

Our MCU is not able to process the analogue signal directly, it needs to be converted into a digital signal before it can be processed, so how can we convert the analogue signal into a digital signal? This is where Pico:ed's ADC function shines through.

Unlike another smart tricycle on the market, which can only load goods, this one can not only load goods, but also turn automatically when it encounters obstacles ahead, and when it encounters strong UV rays, it will also sound a voice alarm and automatically back up to a place where the UV rays are weak.

The Pico:ed is a development board based on Raspberry Pi RP2040 MCU which has a passive buzzer onboard. We know that micro:bit is able to play music by MicroPython, thus, how to play music with Pico:ed?

Aircraft Carriers are large surface combatants that provide a base for maritime activities with aircraft as their main combat equipment, or "carriers" for short. Aircraft carriers have become an indispensable weapon for modern navies and one of the most important ships in naval warfare. By relying on aircraft carriers, a nation can exert military pressure and conduct operations far from its territory and without relying on local airfields. Aircraft carriers have become an indispensable tool for modern navies and a symbol of a nation's comprehensive national power. That's right, today we're going to do it with the "ELECFREAKS Aircraft Carrier"! Let's see how I did it!

The advanced technology in modern societies helps a lot in the technical development in improving the working efficiency and the safety for dangerous works, and we’ve also prevailed a lot of works for our blogs with the emphasis on the combination of the technology with the construction, the health data monitoring, the vehicles assembly and etc., but seldom have we considered the possibility of combining the technology with arts. Here in this blog, we’d like to have a try on doing a robot project which could be applied to draw a picture with watercolors, and definitely, this robot could be assembled from our Nezha Inventor’s Kit. Here we go!

I wonder if you are confused when giving toys to your children as to what kind of things they will enjoy and have meaning. In recent years, the STEAM concept has become popular, aiming to develop children's multi-threaded working skills through creative play and learning inspiration in a holistic manner. With this, STEAM toys have become the perfect starter toys for young creators.

The heat of summer is unbearable. What can you think of when you think of summer? Chilled watermelon, the sea, ice cream and air conditioning are the things that can make me feel a little bit cooler to soothe our hot mood. What if we walk outside without air conditioning? Does one thing flash in your mind at this moment? That is a fan! It may be easy for you to build a fan with blocks, but how to make an intelligent temperature-controlled fan that can achieve face tracking?

Acrobatics is a kind of performance art and is the general name of various juggling, magic, and animal-training play. Its characteristic is to play all kinds of extremely difficult skills with artistic moves, to show the courage of human beings to defeat nature and provoke themselves, and the work that is impressive and hard to believe.

With the development of modern society, sky buildings are one of the most obvious characteristics of civilization. Thus, there are so many mechanical machines invented to help people fulfill the demands of making such big building projects to save both time and labor force.

It’s important for the new generations to understand how these machines could work by the working principles and the combination of advanced technology. Here in this blog, we are going to build the robot car with a mechanical arm with ELECFREAKS micro:bit Nezha 48 IN 1 Inventor's Kit.
