Based on the ESP32 IoT, the smart farm integrates multiple sensors such as a photoresistor, a soil moisture sensor, a water level sensor as well as a WiFi wireless communication module in a way that achieves automation, wireless operation and intelligent management. What’s more, it is capable of realizing intelligent functions such as sensing, early warning, decision-making and analysis.
Therefore, the product contributes to helping you master how to use sensors to build an IoT system, and how to realize smart farm management via KidsBlock graphical programming.

By the way, detailed projects, sample code and LEGO building are provided in it, thus enhancing our hands-on ability, creativity, scientific and technological innovation awareness as well as problem-solving ability

As an introductory project for smart farms, lighting up LED is one of the most basic KidsBlock (based on Scratch) practical projects. It is designed to let beginners understand the hardware and software programming of kidsIOT board (based on ESP32) and master basic circuit and programming knowledge.

In this project, you will learn the basic connections and settings of the kidsIOT board in the KidsBlock graphical programming environment, as well as control the digital pin to output level to control the state of LEDs, LED breathing lights, and button control of LEDs, and you can also apply them in your home or lounge.
