Introduction Arduino isn’t solely for complex projects; it can also serve as a platform for simpler ones, imparting valuable skills to beginners. Our aim is to demonstrate the fun side of electronic components, educating others about circuits and components. In this tutorial, let’s embark on creating an Arduino Sunflower DIY project. This type of project […]
Introduction This guide provides a concise overview of initiating Arduino microprocessor programming through the Arduino Integrated Development Environment (IDE). While these instructions cater specifically to the Arduino Nano board utilizing the ATmega328 microprocessor, a similar process should be applicable to various Arduino boards. Please note that this guide does not serve as a comprehensive introduction […]
Introduction For many electronics projects, AVR microcontrollers are commonly used. However, as a beginner, uploading or flashing code to an AVR can be challenging to understand. When other programming hardware is unavailable, an Arduino board can help burn bootloaders onto AVRs. It also enables creating and testing AVR programs. Therefore, this article will demonstrate using […]
This standalone automatic fan speed controller project regulates the rotational velocity of an electric fan based on dynamic feedback. By leveraging embedded system technologies like a microcontroller and closed-loop control architecture, it provides efficient and reliable temperature regulation. The ATMega8/168/328 MCU allows for nimble adjustments to fan speed based on real-time sensor readings. An LCD […]
Increasing noise levels have become a major issue in many urban areas today due to factors like population increases, urban development, and technological advancements. Moreover, excessive noise from a neighbor or colleague can seriously impact one’s well-being and quality of life. Conversations conducted at high volumes in office settings are understandably disruptive. Having a coworker […]
This project demonstrates an Arduino Uno-based window alarm annunciator system. Annunciators are commonly employed in industrial settings like manufacturing facilities, power plants, and other process operations to monitor changing plant conditions. The annunciator alerts operators to any abnormal or deviant parameter readings that require attention. Similarly, such a device can serve as a home security […]
This project details the development of a wireless Arduino frequency meter capable of determining the frequency of AC sinusoidal waveforms between 50Hz and 3kHz. Figures 1 and 2 depict the prototype hardware constructed for the transmitting and receiving functions. Figure 1 shows the transmitting circuit board which incorporates the frequency sensing components. Figure 2 presents […]
This circuit demonstration showcases a random LED flasher controlling twenty lights. LED flashers and sequencers are commonly employed in decorative lighting applications to produce aesthetically pleasing color patterns. Rather than steadfast illumination, these systems cycle LEDs on and off in either a predetermined sequence or at irregular intervals. The latter approach generates a more dynamic, […]
It is common for parents to feel concern for their children when they are apart. Questions arise around whether the kids made it safely to school, if they are alone at home, or playing with friends at the park. Ensuring a child’s well-being when away creates worry that is familiar to caregivers worldwide. The natural […]
This project demonstrates building a real-time clock (RTC) with temperature display using an Arduino, DS3231 RTC chip, and SSD1306 OLED display (128×64 pixels). The DS3231 RTC chip provides more accuracy than the DS1307 and incorporates an onboard temperature sensor. It maintains timekeeping even without the main power, making it well-suited for this application. It communicates […]
