Tutorial: Automatic Smart Fan Step-by-Step w/Arduino Nano, Shield, DHT11, Relay Switch & mBlock 5

This video tutorial guides viewers through building a smart home automation device using Arduino. It covers the hardware components required, the assembly process, and the software setup using mBlock. The tutorial includes programming instructions to control a fan based on temperature readings from a DHT11 sensor. Viewers learn to test the device and save their program, ensuring the fan operates correctly when the temperature exceeds or falls below 30 degrees.

What is the primary function of the smart home automation device discussed in the video?

• To monitor humidity levels in the house

• To turn a fan on or off based on temperature

• To adjust the thermostat based on time of day

• To control lighting based on room occupancy
