Features

CPLDs — Part 2: Graphical Programming of a CPLD

We’ll get right into some CPLD programming and look at breadboarding and testing, as well.


Give Your Robot the Bootloader

Bootloading provides a very useful layer of control. Once the base bootloader code is loaded into your robot’s program Flash, you can read, write, and erase it without having to use a hardware programmer.

Making Robots With the Arduino — Part 6

Follow That Line!


VEX Stepper Motor Control Experiments

This time, build a simpler version of the SunBot with beefier stepper motors that are powerful enough to directly drive the solar panel’s azimuth and elevation axes.


Build Your Own Big Walker

Part 3. This segment focuses on the design and implementation of the bot’s multi-processor distributed processing system.
