As many of you know, it is possible with many types of displays, such as LCDs and LED displays, to create your own custom characters and, naturally, display them. However, to create your own characters, you need to be able to create a bitmap of how your character (or characters) look. We will be working with the PmodOLED and it’s corresponding library to create our own characters.
If you’ve been keeping up with our blog, you’ve probably seen something about us setting up our very own MakerSpace here at Digilent. We’ve come a long way from a few cluttered cubicles to getting our MakerSpace up and running. We have just about everything you can think of to make any project imaginable: a 3D printer, a soldering station, breadboards, buttons, copious amounts of LEDs, and more! I thought up a just-for-fun project and wanted to test drive the MakerSpace to see what I could build.
With Halloween coming up soon, I decided to make a cool Halloween prop using Digilent products. After grabbing a chipKIT uC32, a couple of shift registers, a bunch of LEDs, breadboard jumper wires, and a PmodMAXSONAR, I was able to make a distance detecting Halloween Box Monster.
At one point or another, we have all played the “Simon Says” game. In this game, one person, Simon (or Susan, Chad, or whoever happens to be the leader), will say “Simon says” and tell all of the other players to do something, such as raise their left hand. The catch in this game is that if the leader tells the other players to do something without saying the words “Simon says” and the other players do it anyway, they’re out. I personally really enjoy playing Simon Says, but I thought it could even be more fun if you could play Simon Says with a bunch of LEDs…
Coffee is taken very seriously here at Digilent, as it is in most workplaces. Something that used to make me mad was not knowing when my coffee hit that perfect “Goldilocks” temperature zone where it didn’t burn my mouth but was warm enough to fully enjoy. I am currently working on developing a thermocouple Pmod using Analog Devices MAX31855 and thought of a great application project. If I could somehow sense how hot the temperature of the coffee was, I could have a microcontroller tell me when my coffee hit the perfect temperature range!
I’m very proud to say that my For Cheap Robots project is still going strong! As some of you may recall, at the beginning of last month, I announced the beginning of my For Cheap Robots series here on the Digilent blog. Since then, I’ve added several more tutorials to the list and gotten a huge amount of positive feedback. I want to thank any and all of you who here who follow the Digilent Blog and decided to pop over to Instructables to check it out!
As I mentioned in my previous blog post, I designed the proximity-sensing LED circuit to eventually move it on to a printed circuit board, or PCB. This was my first experience with PCB layout, and thankfully it was successful! The board I designed is in the picture below. We ordered 6 “prints” and soldered them in our MakerSpace. I also included extra vias (electrical connections between the layers of the board) so that we could connect multiple boards together.
A good display is hard to find. So when I came across the Adafruit’s 1.8″ 18-bit color TFT LCD display with microSD card breakout I couldn’t wait to get it working on our chipKIT boards.
Hello, all! I just finished a new project, the motion-activated AC switch.
Microcontrollers can be utilized in a wide variety of applications, including musical applications. In keeping with this theme, I’m going to take a look today at how to create my own adjustable metronome using …
Today I’m going to take a look into how to make a digital thermometer using parts from the chipKIT™ Starter Kit.
Are you into analog circuits? Check out the video below to see a demonstration of a theremin that I built with the Digilent Analog Discovery using a soda can as the antenna!
Data rates on serial and parallel transmission lines are increasing rapidly. So are the data integrity issues developers face. Eye diagrams make their life easier. Higher data rates in telecommunications …
Ever wonder why oscilloscopes require bulky BNC cables with those fancy switches, while multimeters seem content with plain wires? The key lies in how these instruments handle electronic measurements. One …
Digilent has partnered with CircuitBread to create high-quality electrical engineering lessons on the topic of DC Circuits. Utilizing Digilent’s resources and engineers in conjunction with CircuitBread’s experience in educational content, …
A software-defined radio (SDR) is not a radio in the traditional sense. Instead of fixed analog components with limited range and ability, an SDR is programmable and highly flexible. Referred …
