IoT based automation with Feedback using Raspberry Pi, WROOM32 and a Android Phone
Hello Friends, IoT i.e Internet of Things is a term we all get to hear more often these days. Two machines talking to each other is something we could've hardly imagined a decade ago and today IoT forms a base of growing technology in the digital world. It is present in almost our every activity, right from when we wake up and receive reminders about a scheduled Zoom Meeting, or a booked flight or an aunts birthday from Google calendar to when we go to bed with our Digital Wrist Band which probably is accumulating and analyzing your health data and monitoring your health while you are deep asleep. Having a deep understanding of IoT and related concepts, applications and challenges like security and privacy is therefore essential. So let's dive into the Project. We will need 1. A smartphone 2. Raspberry Pi 4 and later versions (or a WiFi adaptor if you have an earlier version of Pi) 3. ESP WROOM32 board 4. 1K potentiometer (for calibration) 5. LDR 6. Relay module Step 1: Creat
