Arduino is a microcontroller that allows numerous enthusiasts students and professionals to transform any concept they have into an operational electronic gadget. In this course we employ it to build two practical devices from scratch: a weather station and an irrigation system. We explore the necessary hardware and software including DHT11 and FC-28 sensors Arduino IDE and Fritzing. The schematics and code are well-documented making it easy for users to understand what each component accomplishes.First we explain how to construct a weather station which is a device that employs a variety of sensors such as temperature and humidity sensors to gather information about the weather and surrounding conditions. The station's objective is to produce precise readings which will appear on a display. The DHT sensor RTC module LCD wiring to an Arduino UNO board and how to write simple code lines and run your tests will all be covered.The course then goes over every stage of creating an automated irrigation system which may help preserve water funds and work while also playing a big part in conserving the environment. You'll grasp how every piece in the system operates and how to connect them beginning with the soil moisture sensor and finishing with resistors. Additionally included is a complete description of the coding process. This course will equip you with all the skills to create Arduino-based products and simplify your life.
