Introduction
Thank you very much for purchasing the bits pot yellow (referred to as this starter kit or the starter
kit hereafter).
This starter kit is a beginner’s kit intended for those who wish to start learning microcontrollers and
on-board network processors. The kit is designed so that the beginners who ask “What is a
microcontroller?”, “How does it work?” and “How does it control a network?” can easily learn what
it is.
The kit includes flash microcontroller development tools, so if you have slight understanding about
the C language, you can rewrite a program to let the microcontroller perform in various ways. Even
if you do not know of programming, you may be able to enjoy learning a microcontroller with a
study-aid book about the C language.
This starter kit can also serve as an introductory training tool for electronic circuit practice or future
embedded software development in a class of a college or high school of technology or training for
freshman engineers of a manufacturer.
