Continue reading →: Learning the basics of Arduino on CourseraFor a long time, Coursera and other online learning sites didn’t offer much in the way of electronics courses, and there was particularly little related to embedded electronics. That has changed, and now quite a few courses are not only available, but are self-paced, making them more attainable for busy…

Continue reading →: Graph Arduino with Processing!
Having just started getting the feel for programming C/C++ with Arduino, I always wanted to give Processing a shot, being vaguely aware that Processing has the ability to catch serial from Arduino, and put it on a pretty graph. It’s just that Processing is Java, entirely new ground. And for…

Continue reading →: Arduino Guided TourHum. Or maybe a walkthrough. This is a very cute and easy top understand video on what an Arduino is, and what it contains (here). It is produced by the YouTube engineerzerochannel. They have several other videos, most of which are run-throughs of small, easy to program Arduino functions and…

Originally started in Italy as a project to provide students with an affordable, easy-to-use platform for interactive design projects, the Arduino has gained a huge following in only 5 years. It has redefined prototyping tools that were formerly out of reach for the non-engineer, allowing for the combining of art, robotics, automation, and…

After a long period of absence, Electronics Deli is up and running again. Probably because our CEO, HR sales manager, and Chief Webmaster were away in the far-east for a month and a bit. (Kind of makes you wonder how big this organization really is, isn’t it?..) We came back…

Continue reading →: Ladder Logic in PIC and AVR?
Here is an interesting compiler program – symbolically program with ladder logic, then compile into PIC or AVR code. Which is pretty cool considering that ladder logic is usually the realm of PLC equipment handlers. There are limits to what it can do, and you still can’t use a PIC or…

Continue reading →: Arduino: Getting started
What is it? An Arduino is a microcontroller development board – an ATMega chip with all its necessary circuitry, I/Os, power supply and bootloader to program and operate the chip via serial or USB. These boards are becoming increasingly popular due to their realistic price (expect paying a few hundred rand…

When it comes to understanding concepts like Ohm’s law, how current “flows”, understanding what a transistor is and how it works, or the basics of digital circuitry, it’s not always easy to visualize what is going on, especially if the focus of a course is more theory than practical. Falstad.com has…

Often engineering newbies (like myself) hear a lot of terms that are spoken of in the same paragraph: SCADA, Ladder Logic, OMRON, human machine interface… These terms are some of the things heard when people talk about industrial automation, mechatronics or process control. Each is equally deep and wide in scope,…

Ever seen how the charging station of an electric toothbrush has no copper contacts? How does it charge the brush? This is a good example of inductive charging. This way of charging up appliances is becoming more and more common. Many new types of i-whatevers and cellphones can be charged from…
