Year 2 - The internet of things

There many different connection types that can be used. So it is not about wifi all the time. It really depends of what you really need, how much energy it is going to take to the device, how much data you can transfer. In this course, we are going to see the main ones such as:

• USB connection.
• Internet connection through HTTP requests.
• Bluetooth.
• Radiowaves.
• Bar codes.
• NFC/RFID.

But there are many more.
