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.
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.
This is a simple car, I want the children to apply the knowledge of gear acceleration that they have learned in the course of the gyro launcher，and transform this simple car to make the car drive faster; or by replacing the tires. To increase the speed of the car...
What is noise? In our daily life, all sounds that interfere with people's rest, study and work, and interfere with the sounds you want to hear, these sounds are collectively called noise.
Hi, today I’d like to introduce how to make a simple thermometer with micro:bit. I used the microbit to get the temperature and control the steering gear. First, let us start with the design part, and then we will enter the programming part.
This is a simple "swimming robot". Of course, it can't swim in the water but is able to move on the ground by “swinging” its arm. This project mainly aims to guide children to think about how to speed up by using different materials and the touching places to the ground.
The hot seasons are always sweating us and making the body sticky and uncomfortable, which would lead to the loss of body water, and you feel a dry tongue, even to catch a heatstroke. Therefore, a suitable cooling device would be helpful. We have many cooling methods, such as: air conditioning, fans, frozen drinks, etc. Let's make a simple little fan today.
