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.
