I recently bought on ebay the PCB for  this open source VFD shield , designed and made by Axiris, a company in Belgium. I was attracted by the solid documentation provided on their site, which includes the schematics (even Eagle files), assembly instructions, demo software, files for laser-cutting the enclosure. I should also mention the professional photos, rivaling those of the top sites (e.g. adafruit, sparkfun). Assembly went smoothly, as expected. I also expected it to work on the first try, like the other two VFD devices I built previously, the Ice Tube Clock and the akafugu VFD clock . I guess I ran out of luck :) But, as my kid would say, "losing is learning". This became an opportunity for me to actually go one step further than just soldering the components mindlessly (because the instructions are too easy :) This is how I learned what fascinating little devices VFDs are. They function similar to cathode ray tubes (CRT), used in the previous generation of TVs: the

A while ago I built a battery-powered single digit Numitron clock.  There was nothing challenging about it. Each segment of a Numitron takes less than 20mA, like a LED, and requires between 3.5V and 4.5V to light up. So the segments can be driven directly from the processor or other TTLs (shift registers etc). Since Numitrons behave so similar to (7-segments) LEDs, why not use one of my old LED matrix shields to multiplex 4 of them, I thought. And instead of the current limiting resistors, I would use Schottky diode s, to bring them even closer functionally to LEDs. I would even be able to use the same interrupt-based code for multiplexing. I started the practical experiment with just one Numitron. The 7 segments are driven by a 595 shift register and the common electrode gets grounded through a ULN2803 gate. The diodes insure the current flows in one direction only and they also guarantee a maximum voltage of 4.5V on each segment. In practice, multiplexing does not work very well wit

LED is Light Emitting Diode play a really necessary role within the embedded system design. A Diode is a two terminal component within which current flow from the positive direction to negative direction. During this article, we tend to find out how to interface an LED with an Arduino. Simple LED is shown in the image. LED In this tutorial, I will able to show you to run three LED at the same time using your Arduino board.  Component Required: Arduino UNO Board 3 LED Wire Power Supply How to Install An Arduino Library For Proteus Circuit diagram: Circuit diagram of interfacing LED with Arduino board for running three led at the same time is shown below: Circuit Diagram NOTE: Add a current limiting register in series with led to prevent it from damage.

Arduino is a terribly famed microcontroller board. Each engineer, student or hobbyist needs to verify it projects design in real time environment before assembling it on real hardware. Proteus is that the initial alternative for this however in Proteus software there's no library available for the Arduino. Therefore, during this article, you find out how to verify your Arduino project in Proteus by using the Arduino library. First of all, you have got to download the Arduino library for the Proteus software. For this, you will be able to search on Google or download from  here . After downloading the file extract the .rar file and copy the two file name as Arduino.idx and Arduino.lib  Now paste the copied file in the subsequent path      Drive C >> Program files >> Labcentre Electronics>> Proteus 7 Professional>>Library If you want to buy an Arduino development board then you can buy your first Arduino board from here ARDUINO Now open Proteus software and s

An Arduino is a open source platform. Arduino relies on 8-bit AVR family micro controller and 32-bit ARM processor that follows the standard schematics and flashed with arduino boot-loader. Arduino is open source as a result of standard schematics is open for everybody and everybody will create their own board by following the arduino standard schematics. An Arduino board supports each digital and analog output. Arduino board are often programmed by using the Arduino IDE. An Arduino board will communicate with different peripheral using standard communication technique like USART, I2C and USB etc. Some Arduino square measure  Arduino Uno  Arduino mega Arduino Pro Arduino Leonardo        How to Install An Arduino Library For Proteus Arduino IDE is written in JAVA that comes with a software library that refer to as wiring.

Making a proper enclosure for the HDSP clock is challenging, since it was designed specifically to stand on a phone charging dock. Inspired by DaveC's lay-flat version  (he didn't send photos of the inside though), I put some thinking into how to easily convert the "stand up", vertical clock, to an "encasable" horizontal one. The main requirement is to place the display perpendicular to the board. This could be done using a right-angle header of some sort, as shown in the photo below. With this easiest solution, as you see in the next photo, the board must be upside down for the display to show properly. With a bit of more work, basically re-wiring the connections to the display on the adapter PCB (that holds the display), the whole device looks more appropriate, as shown in the next photo. Which brings me to the subject of "display adapters". Although the HDSP clock was designed specifically for HDSP-2534 , it can be easily converted to use simi
