I just happened to see some large strips of LED lighting when I was picking up some parts at Maplin which were on sale (if I remember correct they were around £12 per approx. 2m strip) however the controller/driver was still around £40, so I thought I would just build a better one myself. I […]

This Instructable will demonstrate the building of a bare bones (and really inexpensive… less than $5) Arduino compatible module that can be put together on a small piece of stripboard and can be used either on a breadboard or independently. The following links / similar projects were used as inspiration: * http://www.instructables.com/id/Small-form-factor-DIY-Arduino-on-stripboard/ * http://tinkerprojects.blogspot.com/2012/06/minimal-arduino-on-small-stripboard.html * http://shop.moderndevice.com/products/rbbb-kit * http://txapuzas.blogspot.com/2010/07/paperduino-stripboard.html The

The Arduino library has always had an “analogWrite()” function, even though the ATmega doesn’t have any way to generate a varying voltage. So why the name? Well, what most microcontrollers can do is generate a pulse-width modulated signal, also known as PWM. That’s just a fancy way of saying that the microcontroller periodically generates a

Push the knobs The knobs all have convenient actions if you push them: pushing Vertical Position or Horizontal Position centers the trace vertically or horizontally. Pushing Tigger Level sets it to zero. Pushing Scale sets it to fine adjust mode. Long Memory If you don’t use Long Memory, you’re wasting most of the capacity of

To display the wave I am using XOSCILLO, a very cool and open source tool (which I wrote :P) that converts your Arduino into an oscilloscope. Circuit diagram Here is the scheme, I am using the typical instrumental amplifier(ins amp) and then another op amp to get some more gain. An ins-amp is like an

The BareDuino Nano is the world’s smallest Arduino compatible board. It was designed by a very young maker, Niek Blankers, aged 15, from the Netherlands. Niek has been interested in electronics since he was less than 8 years old. A couple of years ago when he was given the first Arduino board, he fell in

UPDATE: Please note that there no relation between my app and the one with the same name that popped up on Google Play July 3. As for the name ANDRUINO there’s a good chance I might change it to avoid any confusion. – July 7, 2013: I have completed a comprehensive round of testing and

Pong was the first ever videogame that reached the mass market. For the first time in history, the concept of a “video game” was brought into the family home, thanks to the Atari 2600 – so it’s only right that we pay a little homage to this historical gem. Now, you can re-live that (admittedly

A light meter is a device that measures the intensity of light. It finds applications in schools, hospitals, production areas, passageways and more to measure and maintain proper lighting levels. It is often used by photographers to determine the proper exposure for a photograph. Today we are going to build a simple light meter using
