WebIOPi is capable of doing a lot more than this though. It provides a Python library
that contains support for all kinds of GPIO interactions, including explicit support for
digital-to-analog converters (DAC), analog-to-digital converters (ADC), common sen-
sors, I2C, serial, and SPI devices.
Additionally, the web application itself allows you to monitor and debug these same
devices and connections. It also includes Java and Javascript libraries that will enable
you to make custom web (and Android) clients to interface with and remotely control
devices that are connected through the Raspberry Pi GPIO.
Finally, because WebIOPi talks REST, you can interface to it through any other lan-
guage that you choose, but the native libraries are a bit more friendly.
