Summer of Digilent

As the school year comes to an end and people and families prepare for their vacations, their minds begin to relax. To keep those minds sharp and focused, it may be time to start a summer project. Going through the Internet to find such a project can be tedious and time-consuming. If you don’t want to spend time going through thousands of Instructables, then maybe we can help. Let’s take a look at some of our projects and products that could help fill those lax summer hours.

How to Choose a Resistor for Your Design

Take a look at a circuit board and chances are you’re going to find a resistor or two. Most boards today use surface-mount device (SMD) technology, so the components are almost too small to see sometimes, but they are on there, I promise. How do engineers decide which resistors to use in the design? Sometimes it depends on how you want that portion of the circuit to perform, as in the case of an op-amp. Other times it’s to prevent too much current from passing through a given point in a circuit, which is why they are often called current-limiting resistors. Maybe you want a simple way to divide the voltage or current. The reality is that there are numerous ways to use resistors, and oftentimes, the defining the resistor value is up to you.

Shift Registers

Earlier, I made a post on how a shift register is operated in practice. But what exactly can a shift register be used for and how does it work? As always, the answer will depend on what you are trying to do (yes, we do have to play by reality’s rules).

A New Intern’s Experience Getting Started with chipKIT and Learn.Digilentinc!

Howdy! I’m the latest addition to the Digilent family, and I’m happy to make your acquaintance! As the newest member, my first task was to act as a guinea pig to test out our new Learn.Digilentinc webpage. After all, I was new to chipKIT, but I’m no fresh-faced newb (well… not much of a newb), I know my way around a microcontroller and this is hardly my first time blinking an LED, but I’m not a hardcore programmer or electrical engineer either, which was exactly what the Learn.Digilentinc website was created for. So I was asked to go through Digilent’s Learn site to familiarize myself with their hardware, and provide a little outside perspective on the tutorials. The following is a review of my experience with our Learn site, tutorials, and what sort of difficulties folks new to microcontrollers might have while learning the ropes on our hardware.
