Racing Robots!
Have you ever wanted to prove your superiority by embarrassing a friend in a race? Well, now you can with my racing robots project! Using the chipKIT WF32, a Leap Motion Controller, and LabVIEW, I was able to use the Leap Motion Controller to control the speed of a robot.

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.

The Amazing Line-Following Robot Brothers
Here at Digilent, we believe that makers are learners! This means that we want people to take our stuff, and make something new from it. One great example is what this blog post is about– the line-following robots! One of our community members made an alternate, 3D-printable design for our base plate!

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.

What Is an H-Bridge?
One of the most exciting things you can do with electronics besides blinking LEDs, is make things move. What’s the most common way to make things move? Motors. If you’ve done much with motor control, you’ve probably heard of H-bridges. But what exactly is an H-bridge?

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.
