Quantity and quality both matter in starter learning kits. At the heart of the kit is the controller and repetitive circuit program- ming.
It contains the most fre- quently used basic components such as resistors, LED diodes, buttons and potentiometers, as well as a variety of common environmental detection sensor modules, such as sound, water level, soil, temperature, and humidity sensor modules. Whether your project is simple or slightly more complex, you'll find the right tools and materials in this kit.
Low cost can also easily carry out various experiments, ideas and introductory learning.

What programming software is required?
