Introduction This project demonstrates the use of AVR microcontroller ATmega8 to build a smart code lock system. The code lock allows users to gain access by entering a correct password using a 4×4 keypad. It displays messages on an LCD screen and activates a relay to control access. This project covers many useful techniques for […]

The AT90PWM81 microcontroller can produce pulse signals with varying duty fields called pulse width modulation (PWM) that can be utilized in control systems like motor control, brightness control of lighting, and many others. In this commentary, I aim to give a summary of what PWM involves, the methodology behind it, and how the AT90PWM81 microcontroller […]

The growing demand for high-quality materials for use in PCBs continues to grow day by day as our technology continues to evolve. Many brands have been developing materials and components for PCBs to meet this ever-growing demand. Among these brands is a notable name since the 50s, and it’s none other than the Rogers brand […]

High Level Design Inspiration Our inspiration stemmed from photographs that freeze fleeting moments, like a water droplet splashing from a faucet or the split-second burst of a balloon. Such precise instants are often too swift for human reaction or standard camera shutter speeds to capture reliably. To tackle these challenges, we opted to integrate a […]

Objectives There are a few objectives that need to be met to get this project done: These objectives will act as a guide and restrict the system to be implemented for certain situations: To develop a model of REAL TIME WIRELESS FLOOD MONITORING SYSTEM by using the ultrasonic sensor to measure the water depth in […]

1. Introduction Digital Signal Processing (DSP) is a branch of engineering that focuses on manipulating signals, such as audio, video, temperature, and other data types after converting from analog to digital form. DSP techniques improve signal quality, extract valuable information, and enhance system performance. This field combines electrical engineering, mathematics, and computer science principles to […]
