In Part 1 of this series, we built a simple REST API in JavaScript on our Raspberry Pi.
One of the most useful reasons for providing your Raspberry Pi with a REST API is to expose its input and output ports via the Internet for remote monitoring and control. This will allow you to control your RPi’s inputs and outputs from the browser on any smartphone or PC wherever you are in the world.
