I'm curious, what methods should one follow to enter the IoT world? Where should we start to get the basics? Should we start with hardware or software first? Or do we need to work on both simultaneously? For instance, is it more logical to start with sensors, or should we try cloud-based solutions? Which path would you prefer? Also, I'd like to get your ideas on project ideas—what are some of the simplest things that can be done?
Where should I start with IoT? General steps

Wow bro, yeah there's this whole IoT kangaroo out there, at first it's super confusing—I was lost too. My advice? Start with **basic electronics**, get familiar with boards like Arduino or ESP8266/ESP32. Like, ESP32 has Wi-Fi/Bluetooth built-in and it's dirt cheap—perfect for starting with sensors. Grab a temp sensor (DHT11) and a light sensor (LDR), build a simple circuit, and send the data to your computer. This way, you get hands-on with both hardware and basic software.
Then slowly move to the **cloud side**, like using free tools such as "ThingSpeak" or "Blynk" to push your data online. For example, you could make a home temp monitoring system. A simple project idea? An **smart plant pot**—soil moisture sensor + water pump + ESP32 + cloud alerts. While you're at it, mess around with REST APIs in Python/JavaScript so both sides improve. Take it step by step without forcing it—I didn’t even realize I was doing IoT projects every time I upgraded my phone 😂
To get started with IoT, begin with hardware fundamentals—these two often go hand in hand. I started with a Raspberry Pi Zero, using it to learn Linux and blink LEDs with simple GPIO pins. To move on to sensors, I experimented with basic components like LDRs and DHT11s—though I spent over an hour troubleshooting the first DHT11 because I got stuck on wiringPi setup 😅. Once you understand the hardware, you can read data using Python or C scripts, giving you insight into how hardware and software communicate.
For project ideas, start with simple home automation, like a system that monitors room temperature and sends data to ThingSpeak via WiFi. This way, you cover three key steps: retrieving sensor data, storing it in the cloud, and displaying results on a basic web page. Focus first on making sure data arrives, is stored, and can be viewed—don’t dive into complex projects right away. My first IoT project was just a script that sent a Telegram notification when the temperature exceeded 25°C, and even that was educational.
