Mini/Micro projects
-
An Arduino Theremin using Arduino, an ultrasonic sensor, and a speaker that produces varying sound pitches based on the distance of an object from the sensor.
-
A DIY digital piano built using Arduino, an 8-key keypad, and a speaker, allowing users to play musical notes by pressing the keys.
-
An Arduino-based smart fan that automatically turns ON or OFF based on proximity detection using an ultrasonic sensor and controls speed using a DC motor driver.
-
A Rain Detection System using Arduino, a rain sensor, and a buzzer that sounds an alert when water droplets or rain are detected.
-
An Arduino-based smart fan that automatically adjusts its speed according to temperature changes using an LM35 sensor and a DC motor driver.
-
A Soil Moisture Detection System using Arduino, a soil moisture sensor, and a buzzer that sounds an alert when soil moisture is detected.
