Aaaand We’re Off! The Pmod Racing Ruler Roars into Action!
The thrilling outcome to the saga of the Pmod Racing Ruler! Did it measure up? Or did some “speed bumps” prove too much for our dragster?

Richard Wall: Using chipKIT Pro and DC Motors
It may have been a few weeks, but we’re back with the final chapter in Richard Wall’s chipKIT Pro series. The last project focused on using the chipKIT Pro MX7 to control a DC motor. This project expands on that by teaching how to determine the speed of a DC motor by measuring frequency.

Richard Wall: Controlling a DC Motor
After last week’s exciting design challenge, we’re back to a more traditional project — one with an incredibly practical application. We’ll be using the chipKIT Pro MX7 to control a DC motor.

What Is the Hall Effect?
Robots that run around on motors are pretty sweet. These motors traditionally tend to be DC motors that are controlled through the use of an H-Bridge, which can change the flow of current so that the motor is able to run forwards or backwards. H-bridge modules, such as Digilent’s PmodHB3 or PmodHB5, also tend to have two pins labeled as Sensor A and Sensor B that measure which direction the motor is rotating. The two sensors, A and B, will be wired to the outputs of components known as Hall effect sensors. Unsurprisingly, these measure the Hall effect. But rather than having the “word in the definition” problem, let’s learn some of the practical details.

Digilent Pmods — Motor Output
As we continue on with our exploration of the Pmods, after checking out some of the Output Pmods like the DAC, Audio, and Visual Pmods, we find ourselves at the final set (at least for now) of output Pmods. These five Pmods all drive different types of motors including servo, DC, and stepper motors. Through these Pmods, you can get your project on the move, whether its a robot arm, a box monster, or a line-following robot.
