Story

Ek din Ravi YouTube par scrolling kar raha tha jab usne YaranaIoT Guru ka video dekha —“DIY Home Automation: Control LED with Android App” 🌟

Ravi sochta tha smart home banana mushkil aur mehenga kaam hai. Lekin is tutorial ko dekh kar usne realize ki sirf ek ESP32 board aur mobile app se hi wo apne ghar ka light control kar sakta hai.

Usne project follow kiya, ESP32 ko connect kiya aur app se “LED ON” dabaya — aur light jali 🔥Wo moment uske liye magical tha. Ab Ravi apne ghar ka fan aur bulb dono phone se control karta hai — aur proudly kehta hai:

“Smart ghar banana mushkil nahi, bas YaranaIoT Guru ka video chahiye!” 😄
