Sparkfun Electronics launches an educational site

Sparkfun Electronics has launched an educational web site with a full curriculum of classes being held at Sparkfun Headquarters. If you don’t live nearby, no problem. You can download the entire curriculum as well. It appears that they will have a tutorial section for those who prefer a per-project approach, but that area is still “coming soon”. We love to see people educating others. Good job Sparkfun, looking forward to seeing more content on there.

A beginner’s guide to burning Arduino bootloaders

arduino_bootloader_burner

When it comes to learning about microcontrollers, everyone has to start somewhere. [Lady Ada] recently posted a tutorial on burning the Arduino bootloader to standalone chips for those just getting started with the micro.

The tutorial cites a common situation, where someone is working on a project using an Arduino chip but they don’t want to sacrifice their dev board when just the micro and a few other components would do just fine. A short list of supplies is required, including an Arduino, a proto shield kit, a ZIF socket, and a blank ATmega chip.

The process is probably pretty straightforward and likely familiar to many of you out there. The ZIF socket is soldered to the board and handful of wires are added for powering and programming the new chip. The protoboard is installed on top of the Arduino like any other shield, and using a sketch that [Lady Ada] has made available, the bootloader burning process is a cinch.

It’s a useful tip for newcomers, and definitely a skill that seasoned Arduino users should have under their belts as well.

Electronics lessons for beginners

electronics

Hackaday reader [grenadier] wrote in to share a series of tutorials he is working on, where he discusses the basics of electricity and electronics. The first lesson titled, What is Electricity?” has been wrapped up, and is available for free on his site.

For any of our regular readers, the lesson will seem pretty basic (and likely full of things to nitpick). However, we imagine his lessons would be quite helpful to anyone looking to expand their electronics know-how.

Now don’t get us wrong, we love the series of electronics tutorials that Jeri has been periodically releasing, but we think there’s plenty of room on the Internet for other willing teachers as well. If his first lesson is any indicator, his tutorials will be easy to understand, sprinkled with a little bit of humor, and chock full of fun videos that demonstrate the subject at hand.

Take a quick look his way if you get a chance – you or someone you know might find his tutorials and reference guides insightful.

Learning electronics concepts step by step

arduino

We realize that not everyone out there holds a degree in electrical engineering or has the ability to tell NPN transistors apart from PNP transistors by taste alone, so we occasionally like to mention things that appeal to the beginners in the crowd. While there is a clear division between Arduino supporters and detractors, it is hard to deny that the devices have their place, and can be quite useful when exploring certain electronics concepts.

For the supporters out there, [John Boxall] has put together a site jam-packed with Arduino tutorials covering a wide array of concepts and techniques. We have covered his work before in relation to specific topics, but we felt that his site deserved mention as a whole. His tutorials cover some of the most basic concepts such as lighting LEDs with the Arduino, and work their way to more advanced subjects, lesson by lesson.

He is not satisfied with simply introducing a concept and handing out a sketch that does the work. He takes the time to expand on the concepts, giving the reader enough detail to use their new-found knowledge in later projects. If you were to follow his tutorials from beginning to end, you would be exposed to LCD screen control, shift registers, real-time clocks, I2C bus communications, and more. These skills and concepts can be carried on to future projects as well as other micro controllers, making his tutorials a very valuable learning tool worth checking out.

Beginner concepts in electronics and Arduino

[Jeremy] is all about the Arduino, but also into helping people get started working with electronics. He has put together a series of videos on his web site which discuss the basics of using an Arduino. Having just published his tenth tutorial, he dropped us a line to let us know. His videos cover a wide range of topics and include source code, schematics, and a full parts list to help you follow along with him.

While the core of his lessons focus specifically on how to use the Arduino to perform particular tasks, he does introduce the viewer to many different concepts along the way. He covers PWM, button debouncing, interrupts, SPI communications, analog inputs, and more – all of which are must-know topics that extend beyond the realm of experimenting with Arduinos.

The videos run anywhere from 6 to 20 minutes in length, so you will want to set a block of time aside if you plan on checking them out.

If Arduino-specific videos aren’t your thing, he also has a series of general tech-related videos on his site as well which may be of interest. Otherwise, stick around to see the latest in his series of tutorials.
