This tutorial shows you how to use a Piezo element to detect vibration, in this case, a knock on a door, table, or other solid surface. A piezo is an electronic device that produces a voltage when it undergoes physical deformation from a vibration, sound wave, or mechanical strain. Likewise, applying voltage to a piezo […]

This project is an independent fan speed regulator that automatically adjusts the speed of an electric fan based on real-time feedback. The use of embedded system technologies like a microcontroller and closed-loop control architecture enables successful and reliable temperature regulation. The ATMega8/168/328 microcontroller allows for rapid adjustment of fan speed based on real-time sensor information.

Today we are constructing an Arduino-based Automatic Pet Feeder that can dispense food to your pet at scheduled times. It includes a DS3231 RTC Module to establish the feeding schedule for your pet with accurate time and date settings. Therefore, the device will automatically dispense or refill the food bowl at the set time based
The Automated Missile Defense System is capable of neutralizing airborne threats such as planes, high-altitude ballistic missiles, and low-altitude cruise missiles. Having missile defense systems is crucial for India due to its surrounding hostile neighbors. A Surface to Air missile is a type of missile that travels at a very high speed (2-4 times the
This drawing showcases a rock-paper-scissors game that utilizes three pushbuttons for user input, two hobby servos instead of a human hand to show the countdown and selections, and tone feedback through a speaker. The code is designed to showcase a variety of techniques. non-blocking event polling loop to simultanously process input and output switch-case state
In this tutorial, I will demonstrate how to create a mosquito repellent device with the help of an Arduino. The repellent comes in a shield form that can be connected to the Arduino board, allowing for easy modification of its frequency. This project is perfect for camping and hiking outdoor activities, as it emits a
A simple diagram demonstrating how to regulate the velocity of a DC motor using a potentiometer connected to your Arduino device. Additionally demonstrates the method of utilizing a TIP120 transistor for enabling the Arduino to manage a more powerful power source. Transistors consist of 3 pins, with the third pin (Base) enabling control of the

With the Mouse library, an Arduino Leonardo, Micro, or Due can manipulate the onscreen cursor of a computer. This specific instance involves the use of five pushbuttons to control the movement of the cursor on the screen. Four buttons control direction (up, down, left, right) and one activates a left mouse click. Cursor movement on
For this assignment, your goal is to transform the Arduino into a thermometer! Utilize a temperature sensor to track your skin’s temperature and record the information using three LEDs. The Arduino, being a digital tool, is able to collect information from analog devices such as the TMP36 temperature sensor by utilizing its on-board Analog-to-Digital (ADC)
