Abstract This design project addressed the challenges associated with over-reliance on smartphone screens by introducing a wearable fabric sleeve. The sleeve delivers incoming call notifications wirelessly through haptic feedback and enables touch-sensitive gesture recognition for interacting with smartphones or similar devices. The touch-sensitive grid was crafted using conductive thread and relied on high impedance capacitive […]

A cost-effective and dependable safeguarding solution has been developed to protect a three-phase induction motor from various electrical anomalies including unbalanced voltages, under voltage, over voltage, short circuits, and overheating. To maintain affordability, the design utilizes components such as the Atmega32 microcontroller, MOSFETs, relays, as well as small current transformers (CTs) and potential transformers (PTs). […]

I.      INTRODUCTION Ensuring the protection of induction motors is crucial for their prolonged operational life. While numerous researchers have delved into this domain, many existing protection schemes are deemed impractical and costly within the Indian context. In the event of a phase outage due to fuse failure or protective device activation, three-phase induction motors have […]

Circuit Diagram In the circuit diagram of the School/College quiz Buzzer circuit using the 555 IC, three 555 timer ICs are arranged in a bistable configuration. Each 555 IC has its own stable state controlled by individual buttons accessible to the participants. Additionally, there is a single button that manages the common stable state of […]

1. INTRODUCTION A growing number of elderly and disabled individuals seeking to enhance their mobility find wheelchairs to be the most effective assistive device. For those with mobility challenges, a wheelchair provides the convenience of moving around, either propelled by another person or by the user’s physical force or electronic means. Traditional wheelchairs, however, come […]

Abstract This document details the development and implementation of a wireless fire alarm system, managed by an ATMEGA32 microcontroller, featuring Master and Slave Unit Controllers. The system receives input signals from normally opened warning devices like heat detectors and/or smoke detectors, with the unit containing these detectors referred to as the slave unit controller. The […]

Introduction The popularity of microcontrollers is on the rise, thanks to their compact size and impressive capabilities. Embedded systems are being constructed around microcontrollers and peripheral devices [3]. An oscilloscope is frequently employed to observe the waveform of an electrical analog signal, typically representing voltage, time, and frequency. Parameters such as peak-to-peak voltage, frequency of […]

Abstract This document centers on the utilization of Atmel AVR series microcontrollers and the Tarang Zigbee module to wirelessly monitor environmental parameters such as temperature, humidity, CO2, and moisture levels. Presently, monitoring climate parameters like temperature and humidity plays a crucial role in regulating environmental conditions in residential or occupational settings. This objective can be […]
