Operational amplifiers (op-amps) are everywhere, in everything, and can do just about anything. Well, okay, maybe not quite, but there is no doubt that they are one of the most useful ICs ever to hit the market.
Are you wanting to build something that requires DC power but changing batteries would either be inconvenient or just plain annoying? Here’s a simple how-to for converting AC mains voltage to rectified and regulated DC voltage.
I’m a big fan of the chipKIT WF32. It’s a powerful little board with a WiFi card and SD card reader built in, but there’s a lot more to this board than meets the eye. There are a ton of communication lines, external interrupts, output compare pins, and more hidden in all those GPIO pins, but how do you tell what is what? That’s where the WF32 pin diagram comes in. I’ve compiled, color coded, and listed what each pin is capable of.
Many of you have likely done some soldering before, but if you are like me, you may not be familiar with all the different soldering iron tips that are out there. I know that I used to be under the impression that there were only two types of soldering iron tips and only one useful type–the one currently on the soldering iron.
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).
Here’s a really great educational project for learning about frequency modulation using your Analog Discovery and Analog Parts Kit.
Have you ever been trying to learn how to do something and looked around online for help but got the impression that everybody else knew how to do it but never …
As promised, this post provides some of the tips and tricks for using Fritzing that some of the other interns and I have discovered in our use of the software. I have been working closely with Fritzing to get a Digilent parts bin in the next release, which should happen soon!
Fritzing is a free tool that allows users to create clean and professional images of electronics projects for teaching or sharing. Digilent uses Fritzing in all of our intern-created projects, and we’re working closely with Fritzing to have a bin of Digilent parts soon.
A recent question asked on the Digilent Forum was about how to measure the Total Harmonic Distortion (THD) in audio signals with the Analog Discovery 3. Let’s clarify the options. …
