Program 1
Develop a program to blink 5 LEDs back and forth.
Program 2
Develop a program to interface a relay with Arduino board. To interface a 5V relay module with an Arduino Uno board and control the switching of an electrical load (such as a bulb, fan, or motor) using digital output signals. This experiment helps in understanding relay operation, electrical isolation, and Arduino-based switching applications.
Program 3
Develop a program to deploy an Intrusion Detection System using Ultrasonic and Sound Sensors To develop an Intrusion Detection System using an Arduino Uno, HC-SR04 Ultrasonic Sensor, and Buzzer. The system detects the presence of an object within a specified distance and generates an alarm using the buzzer. This experiment helps in understanding distance measurement, obstacle detection, and security system implementation using Arduino.
Program 4
Develop a program to control a DC Motor with Arduino Board. To interface and control a DC motor using an Arduino Uno board and a transistor driver circuit. This experiment helps in understanding motor control, transistor switching, flyback diode protection, and Arduino digital output.
Program 5
Develop a program to deploy Smart Street Light System using LDR Sensor. To develop a Smart Street Light System using an Arduino Uno and an LDR sensor. The system automatically turns the street light (LED) ON during darkness and OFF during daylight. This experiment helps in understanding light sensing, analog input, and automatic lighting control using Arduino.
Program 6
Develop a program to classify Dry and Wet Waste using Moisture Sensor. To develop a Smart Waste Classification System using an Arduino Uno and a Moisture Sensor. The system automatically detects the moisture content of waste and classifies it as Wet Waste or Dry Waste. The classification result is displayed on an LCD, and a servo motor is used to sort the waste automatically.
Program 7
Develop a program to read the pH value of various substances like Milk, Lime, and Water. To interface a pH Sensor with an Arduino Uno board and measure the pH value of different substances. The measured pH value is displayed on a 16×2 LCD Display and classified as Acidic, Neutral, or Basic.
Program 8
Develop a program to detect Gas Leakage in the Surrounding Environment. To interface an MQ-2 Gas Sensor with an Arduino Uno board to detect the presence of harmful gases in the surrounding environment. The gas concentration is monitored continuously, and the gas level is displayed on the Serial Monitor. The system also generates warning messages when the gas concentration exceeds the predefined threshold.
