We connected our LED to the internet using the dweet.io service and called its RESTful APIs, which are documented at the following:

• Dweet.io API documentation:  https://dweet.io

You may wish to familiarize yourself with the GPIOZero library briefly to get an idea about what it can do. It's well documented with heaps of examples. Here are a couple of useful links to relevant parts of the API documentation that we've covered so far:

• GPIOZero home page: https://gpiozero.readthedocs.io
• Output Devices (LED): https://gpiozero.readthedocs.io/en/stable/api_output.html
• Input Devices (Button): https://gpiozero.readthedocs.io/en/stable/api_input.html

Regarding PiGPIO, here are the relevant parts of its API documentation. You'll notice that PiGPIO is a more advanced GPIO library with less verbose documentation.
