Development Timeline (Dev Log) Day 1 – Planning & Research

Decided to use ESP32 instead of Arduino because it has built-in Wi-Fi

Studied how ESP32 can act as a web server

Learned about:

1.WiFi.h

2.HTTP requests

3.WiFiServer and WiFiClient

Day 2 – Hardware Setup

1.Connected an external LED to the ESP32

Used:

1.GPIO pin 4

2.Current-limiting resistor

3.Verified LED works using a simple digitalWrite() test sketch

Day 3 – Wi-Fi Connection

1.Wrote code to connect ESP32 to a Wi-Fi network

2.Printed IP address on Serial Monitor

3.Confirmed ESP32 connects successfully

Challenges faced:

1.Incorrect Wi-Fi password caused connection failure

2.Fixed by double-checking SSID and password

Day 4 – Web Server & LED Control

1.Created an HTTP server on port 80

Parsed browser requests like:

1./LED=ON

2./LED=OFF

3.Controlled LED state using HTTP URLs

4.Designed a simple HTML page with buttons

Day 5 – Testing & Debugging

Tested on:

1.Laptop browser

2.Mobile browser

Verified:

Real-time LED response

Stable Wi-Fi connection

Cleaned up Serial output

Recorded a working demo video

How the Project Works

ESP32 connects to Wi-Fi

ESP32 starts a web server

User enters ESP32 IP address in browser

Buttons send HTTP requests

ESP32 reads the request

LED turns ON or OFF accordingly

I’m working on my first project! This is so exciting. I can’t wait to share more updates as I build.
