Project Overview

This project was created with the intentions of aiding a physically disabled person. The relay box can simply be plugged into the AC wall socket and any appliance can then be connected to one of the four channels and be controlled online via web UI. The four channel relay board has an onboard Darlington transistor array so it can be triggered directly from the GPIO of the ESP8266 µController.

Key Learnings

• HTML, CSS, AJAX, Javascript, C++
• About the ESP8266 which is a cheap, Wifi enabled microcontroller
• Modeling parts in SolidWorks and creating an assembly to ensure design feasibility
