Today is output day. I’m going to show you how to switch things on and off using RPi.GPIO to control the output ports of the Raspberry Pi.
Once you can control outputs, you can, with a few additional electronic components, switch virtually anything on and off. Given the Raspberry Pi’s excellent connectivity, this means you can switch things on and off through the internet, using any computer, smartphone or tablet from anywhere in the world. You can also use a local network, Bluetooth etc. for short-range control.
