Circuit Cellar - The Magazine for Computer Applications

Since its founding in 1988, Circuit Cellar has delivered exactly what its paying subscribers demand-intensive, exploratory articles about hardware and software methods for embedded-control systems.

Circuit Cellar - The Magazine for Computer Applications

Circuit Cellar Ink, the best magazine devoted to hardware and embedded computer development, or "What's Inside the Box".

Circuit Cellar - The Magazine for Computer Applications

Are you wondering how it all began?
By Steve Ciarcia (Founder, Circuit Cellar)

"His first statement upon hearing about BYTE’s redirection was “How about we start our own magazine?” We had the staff, the expertise, the credibility, the support, and most importantly, the money. It was time to go for it.

Analog Op-Amp Interactive Tutors

I have made some Web Widgets, these are analog opamp tutors. Interactive Tutorial with Simulated Meters and Potentiometers, demonstrating how Operational Amplifier functions in different configurations.

Interactive Tutorials using Virtual Electronic Components 

Slide the Potentiometers just like you would operate a Sliding Control. Drag the Knob on Pot to increase or decrease the resistance. The Resistance is shown is blue letters and dynamically alters value as you slide the pot.


The mV Source is varied by just moving mouse pointer over the two buttons, no clicking. This reduces finger strain and also you have a long lasting mouse. The mV buttons are special, the variation picks up speed if you let the mouse pointer remain on the button. This is Ramp-up and Ramp-down. This enables you to set it faster with just two buttons.

Finally you have a DVM a Digital Volt Meter that just Displays the Voltage at any Point, this readout value has to be noted down.

Arduino Interfacing with Visual Basic

I have tried VB2 and VB6. It is an easy environment for Hardware Engineers or Hobbyists to program. It means easy to code unlike C++. Programs made with the new VB may not be compact or fast; but as it runs on a Virtual DotNet Machine and is bug-safe and may not hang/boot too. The DotNet was MS answer to Java of Sun. Even Java is a simple language and it seems to be lighter too. DotNet of late has become a bigger download, more than 10 times the size it started with.

MS can try Visual Basic Webapp on the Cloud using HTML5. Even remotely hosted DotNet is better, with the VB Apps as Web Applications using DotNet WebService. Then nothing to download, neither the update or the security fixes. Just provide something like jQuery for DotNet. Web VB would be a better thing for developers.

Arduino Interfacing with Visual Basic

Arduino is a QuickStart Embedded system, very useful in learning both the hardware and software elements of a system.

From what i understand, the developed app can be burned into the device fully, no additional layer of OS or Firmware needed, It is all built in. In short the compiled binary can be either a stand-alone firmware(OS) or be a layer running over a Mobile OS.

Now putting Ardunio and VB together, we get an Hardware/Software Environment that is easy on students and hobbyists too.

Fermata written by Andrew Craigie

Firmata is a generic protocol for communicating with microcontrollers from software on a host computer. It is intended to work with any host computer software package. See more examples ….

"Then for those that liked Java, He gave the Processing

thenceforward, the Inspired People made many Large Sketches and the Globe Glowed like Warm White LED Lamp"
