One way is to use I2C or SPI circuits with analog to digital converters. Another way, which we explore in this book, is to use an Arduino board. The Arduino is a programmable chip, and, as such, you can program your own firmware with your own serial protocol inside. A simpler method, is to use the well-used and battle-tested Firmata protocol. Software for this already exists, and is available in the Arduino IDE directly. Libraries for Firmata exist in many languages.
