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 needed, assembly instructions, software setup, and programming using mBlock. The device uses a temperature sensor to control a fan, turning it on or off based on temperature readings. The tutorial includes a demonstration of the device in action, showing how it responds to temperature changes.

What steps should be taken to ensure the correct functioning of the fan based on temperature readings?

How does the device respond when the temperature exceeds 30 degrees?

What should you do if the fan does not turn off when the temperature drops below 30 degrees?
