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
1 Introduction 1.1 Statement of Purpose We selected our project because power supplies represent a crucial yet costly element in electrical projects. From an industrial perspective, many product test setups demand multiple precise voltage references, yet the purchased supplies often possess excessive wattage and expense. For hobbyists and students, the price of a single power
Utilize the ATMega328 and ESP8266 single-board combination for effortless WiFi integration into your Arduino projects, eliminating the need for cumbersome external connections. While this particular development board holds several advantages (to be discussed later), it surprisingly lacks extensive documentation. Given its potential as an ideal platform for WiFi-enabled Arduino projects, this project aims to contribute
