My recommendations for your first robot motors: Voltage: 5V-8V Torque: double what you think you will need There are many websites selling DC motors

Easy Printed Circuit Board Fabrication

You can easily make your own high-quality PCBs (printed circuit boards), from a laser-printer or copier (but not inkjet) printout of the desired copper pattern, using an ordinary clothes iron, and, most-importantly, the correct paper type

Control of Stepping Motors

This tutorial covers the basic principles of stepping motors and stepping motor control systems, including both the physics of steppers, the electronics of the basic control systems, and software architectures appropriate for motor control.

ELECTRICITY AND MAGNETISM

Here is a complete description of electricity and magnetism....

555 Timer/oscillator

The 555 timer IC was first introduced around 1971 by the Signetics Corporation as the SE555/NE555 and was called 'The IC Time Machine' and was also the very first and only commercial timer ic available. It provided circuit designers and hobby tinkerers with a relatively cheap, stable, and user-friendly integrated circuit for both monostable and astable applications.

DC CIRCUITS

Even though this book is lengthy and takes time to complete reading but is very helpful since its covered all the points of Digital Circuits in a simple and understandable way.

Learn About LED's(Light Emitting Diodes

This book contains each and every information about LED right from how it is produced how light is formed till its applications....

How Computers Work

Computers are the most complex machines that have ever been created. Very few people really know how they work. This book will tell you how they work and no technical knowledge is required. It explains the operation of a simple, but fully functional, computer in complete detail.

ASICs(Application Specific Integrated Circuits)

The semiconductor industry has evolved from the first ICs of the early 1970s and matured rapidly since then. Early small-scale integration ( SSI ) ICs contained a few (1 to 10) logic gates�NAND gates, NOR gates, and so on�amounting to a few tens of transistors. The era of medium-scale integration ( MSI ) increased the range of integrated logic available to counters and similar, larger scale, logic functions. The era of large-scale integration ( LSI ) packed even larger logic functions, such as the first microprocessors, into a single chip.

CMOS LOGIC

A CMOS transistor (or device) has four terminals: gate , source , drain , and a fourth terminal that we shall ignore until the next section. A CMOS transistor is a switch. The switch must be conducting or on to allow current to flow between the source and drain terminals (using open and closed for switches is confusing�for the same reason we say a tap is on and not that it is closed ). The transistor source and drain terminals are equivalent as far as digital signals are concerned
