This project simulates an advanced EV powertrain using an Arduino Mega. It features drive-by-wire steering mapped via a potentiometer, and an Adaptive Cruise Control system that uses an ultrasonic sensor to dynamically brake the primary DC drive motor based on frontal obstacle distance."

AutoGuard is a smart object detection and alert system built using Arduino. It uses an ultrasonic sensor to measure the distance of nearby objects and an IR sensor for close-range detection. Based on the sensor inputs, the system processes the data and triggers alerts using an LED and a buzzer. The alert intensity changes depending on how close the object is, providing a more responsive and adaptive system. This project demonstrates sensor integration, real-time processing, and conditional decision-making in an embedded system.

AgroBot is a dual-mode autonomous robot built on Arduino Nano that uses an ultrasonic sensor to detect obstacles and automatically stops when an object comes within 20cm, while also supporting full manual control via an IR remote with mode switching between AUTO and MANUAL using buttons

"This project is an Autonomous Guided Vehicle (AGV) designed to simulate automated industrial logistics. It uses a 3-sensor IR array for precise line tracking and an ultrasonic sensor to detect payloads in its path. Once an object is detected, a custom-programmed 3-DOF (Degree of Freedom) robotic arm automatically executes a smooth pick-and-place sequence to secure the payload before continuing to its destination."

This project demonstrates a simple Spaceship Alert Interface System using an Arduino, three LEDs, and a push button. It simulates two modes of operation: normal and alert. In normal mode, a green LED remains ON, indicating stable system conditions. When the push button is pressed, the system switches to alert mode, where two red LEDs blink alternately to represent an emergency warning. The Arduino continuously reads the button input and controls the LEDs using conditional logic and timing functions. This project helps beginners understand digital input/output, basic programming, and circuit design, providing a strong foundation for building more advanced embedded and automation systems.

A full adder is a combinational digital circuit used to add three binary inputs: A, B, and a carry input (C-IN) from a previous stage. It produces two outputs: Sum (S) and Carry output (C-OUT). The sum represents the result of the addition, while the carry output is passed to the next stage when performing multi-bit binary addition. Full adders are commonly used in digital systems and processors to add binary numbers efficiently.

A half adder is a simple digital circuit that adds two single binary digits, A and B. It produces two outputs: Sum and Carry. The Sum is generated using an XOR gate, and the Carry is generated using an AND gate. It does not include any carry input from a previous addition stage.

This project uses an Arduino and a DHT22 sensor to measure the temperature and humidity of a room. The live readings are instantly displayed on a 16x2 LCD screen that updates every two seconds.

This measures the distance between an object and the HC-SR04 ultrasonic sensor using an Arduino. The sensor sends ultrasonic waves and calculates the distance based on the time taken for the echo to return. The measured distance is then displayed in centimeters on a 16×2 LCD with an I2C module, allowing users to easily monitor the distance in real time.

Smart dustbin that opens automatically and helps identify wet or dry waste. An ultrasonic sensor detects when a person places waste near the bin and triggers a servo motor to open the lid. At the same time, a soil moisture sensor checks the moisture level of the waste to determine whether it is wet or dry, and the result is shown in the Serial Monitor. This system makes waste disposal easier and promotes better waste segregation and cleanliness.
