Arduino & Electronics Interfacing

Description

Students expand their Arduino knowledge by learning how electronic systems sense and interact with the physical world.

They explore a wide range of Sensors for measuring distance, light, temperature, soil conditions, movement, gases, and other environmental variables.

Students then learn how Arduino uses this information to control Actuators such as DC Motors, Servo Motors, Relays, and other electrical loads.

The course also introduces Motor Drivers, Transistors, Relays, and Bluetooth communication, allowing students to progress from individual component experiments to complete Smart Systems.

Through projects such as Smart Greenhouses, Irrigation Systems, Fire Fighting Systems, Radars, and Railway Crossing Gates, students begin understanding the foundations of Sensing, Control, Automation, and System Integration.
