    What is IOIO?

    IOIO (Figure 1-1) is a product produced and sold by SparkFun (among others). It contains a PIC microcontroller and USB interface and a few other glue components to regulate the supply voltage etc. The whole project, both hardware and software is open source.

    To make use of an IOIO, you will need:

    • An Android phone with USB lead

    • A Windows, Mac, or Linux computer

    • A power supply 5-15V DC offering at least 500mA

    Since the IOIO comes without any sockets soldered to its connectors, we will attach some to it and make a power lead for it. To do this, you will also need the parts listed in Table 1-1.
