Choose a Cloud Platform
Compare options like ThingSpeak and Blynk.
Choose a Cloud Platform is a free Arduino & IoT Academy lesson on CoddyKit — lesson 1 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Arduino & IoT Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
Why Use a Cloud at All
Your board can sense the world, but a cloud platform lets you see and control it from anywhere, on any phone or laptop. 🌐
What a Platform Gives You
A good IoT platform handles the hard parts for you: storing readings, drawing live charts, and sending data back to your device.
Meet ThingSpeak
ThingSpeak is free and beginner-friendly. You send numbers to channels, and it plots them as graphs you can share with a link.
Meet Blynk
Blynk focuses on apps. You drag buttons and gauges onto a phone screen, then wire them to your device with almost no UI code.
Data In vs Control Out
Some platforms shine at logging data in, others at sending controls out. Pick one that matches what your project needs most.
Free Tiers Have Limits
Most platforms offer a free tier with caps, like one update every fifteen seconds. That is plenty while you are learning. 👍
Match the Board
You need a WiFi board like the ESP32. A plain Uno has no internet, so it cannot reach a cloud platform on its own.
Look for a Library
Pick a platform that ships an Arduino library. It hides the messy network calls so you write a few clean lines instead of raw HTTP.
Think About Sharing
If you want others to view your data, choose a platform with public dashboards. ThingSpeak channels can be shared by URL.
Create a Free Account
Sign up on the platform's website first. You will get a dashboard where channels, widgets, and device keys all live.
Note Your Channel ID
After creating a channel, save its Channel ID. Your sketch uses this number to send readings to the right place.

Recap
A cloud platform stores, charts, and controls your device data online. Pick one with a free tier and a library, then grab your account keys.
