Gravity: Analog TDS Sensor/ Meter for Arduino

The Microbit Starter kit has provided 24 types of electronic components to help you get started. Micro:bit Starter kit can help your children enter a wonderful electronic world. Note: the micro:bit board is not included, you can buy it separately.

When using the HuskyLens, you may encounter accidental drops, bumps, etc. Now we have carefully designed this silicone case to protect your board.

Note: This product does not include the HuskyLens board.

GamePad for micro:bit V4.0 adopts a high-precision three-axis analog quantity joystick. The combination of joystick and gamepad allows you to control the direction and speed of Maqueen at the same time. In addition, there are 7 programmable buttons, which means you can explore more interesting functions and more flexible controls. In the latest V4.0 product, we have placed the external battery box on the PCB, which is more convenient to use.

The six+ cool projects in this kit will give children new insights into artificial intelligence while they are entertained.

Note: the micro:bit board is not included, you can buy it separately.

The RETRO Arcade for Education is the first large-screen arcade device with high resolution. Children can use it to fuel their creativity by easily creating their games while having fun playing.

Mini electricity generator, built base on a turbine and an electric generator that converts kinetic energy into electricity. The generator output is rectified and regulated for a maximum of 12V. Please note -if we want to generate more current, the turbine will oppose the greater resistance to the flow of water, and the voltage may drop if the water flow is not sufficient. This generator is made of plastic and the turbine is totally isolated from the generator and rectifier, the outputs are 1/2 "usually found in domestic pipes.

NEZHA inventor kit for micro:bit develop your imagination and creativity with the Nehza 36-in-1 kit for micro:bit.

Turn everything into a "keyboard" thanks to the Bitboard.

The meter built on the basis of a water rotor and a Hall effect sensor
