The Nintendo Wii Nunchuk was released in December 2006. It features an analog stick, two buttons, and a 3-axis accelerometer. Due to its low price (around $5 for a used or counterfeit Nunchuk) and I2C bus support, it became an easily accessible option for those looking to add an input device to their project without much hassle. Without further […]

Introduction: With the growing imperative to safeguard data and premises, the biometric authentication sector is witnessing significant market expansion. Our endeavor focuses on creating a scalable, compact, and efficient device tailored for securing doorways within a complex. Leveraging a FingerPrint Cards capacitance-based fingerprint scanner, our system employs an ATMega32 microcontroller for data capture, storing the […]

Introduction This document outlines a prototype board designed for use with the Atmel Mega644 or Mega32 (PDIP) MCU. The board incorporates essential components such as a power supply, crystal clock, and bypass capacitors. Additionally, it features a six-pin header for flash memory programming from devices like STK500 or AVRISPmkII. All port pins are accessible via […]

Here are some potential issues or limitations with the proposed RFID-based access control system design: Privacy/Data Security – Stored RFID tag IDs could potentially be hacked or leaked, exposing user privacy. Proper encryption and access controls would be needed. RF Interference – The RFID reader’s performance could be impacted by other electromagnetic devices/signals in the […]

This project explores the functionalities of the AVR ATtiny4313 microcontroller using three different programming environments: Bascom-AVR, GCC, and Assembly language. The focus is on utilizing timers and interrupts to achieve tasks like blinking an LED. Hardware Setup: The project utilizes an ATtiny4313 microcontroller mounted on a breadboard. A crystal oscillator with two capacitors sets the […]

Introduction With many upgrades and improvements in the electronics industry, meeting the challenge of shielding delicate parts from occurrences such as voltage surges and ESD requires a strategic approach. Unfortunately, these transient events may turn forgotten or neglected, which results in excessive damage. This is a common case for system failures, breach of confidence in […]

Diodes: they’re small but have a big job to play in various circuits. Switching diodes in particular are indispensable, essential for regulating voltage and processing all the signals our digital world revolves around in work, play, and daily living. Most electronics engineers will have to use them at some point, so why not learn about […]

Abstract The Automated Inventory Tracking System (AITS) aims to address deficiencies in the routine management of personal belongings. Specifically, it aims to minimize waste in grocery shopping by providing users with a comprehensive view of their possessions, complete with product names, specifications, and expiration dates. This initiative involves the identification of grocery item barcodes, which […]
