Once upon a time, in a magical land 🏰, there was a wizard 🧙‍♂️ who wanted to control a light using his special powers. To do this, he created a magical server that could listen to messages on a special number, which was 80.

First, the wizard needed a helper, so he summoned a special friend 🧙‍♂️ named “client” to assist him with incoming messages. Together, they embarked on a quest to control a light using these messages.

In their preparation phase 🚀, the wizard connected to a Wi-Fi network with a secret name (“Shemanto Wifi”) and a secret password (“ssssssss”). They had to try to connect every 2 seconds, but they never gave up until they were successfully connected 🌐. Once they were connected, they celebrated 🎉 and proudly told everyone their address 🏡.

Now, onto the magical part ✨! They started their magical server on port 80, which meant they were ready to receive messages from anyone who wanted to communicate with them.

In their daily routine, they constantly checked if there was a new friend knocking at their door 🚪. If a friend arrived (a client connected), they created a special box 💌 to collect their friend’s message.

They were great listeners 🎵! They listened to their friend as long as the friend stayed connected. Whenever a character arrived, they read it like it was a page from a book 📜.

They had a special way of recognizing when a new line character (a “newline”) appeared 🌟. Whenever they saw it, they would share their friend’s message with the world 📣. But before doing anything magical 🪄 with the message, they checked if it was about turning the light on or off.

If the message said “GET /ledON HTTP/1.1,” they used their magical powers to turn the light on by sending a signal to pin number 2 (the LED pin). And if the message said “GET /ledOFF HTTP/1.1,” they turned the light off. They also made sure to clear their special message box 🧹 for the next message.

After sharing the message and performing their magic, they politely said goodbye to their friend and closed the door 🚪.

And so, the wizard and his special friend were able to control the light using the magical server and live happily ever after in their world of code! 🌟🧙‍♂️🔮🏰🎉
