LED signage has become the choice in modern days to convey message to visitors of a venue. Be it corporate office, shops, restaurants or any kind of social functions like marriages. Some big and complicated display needs dedicated control PCs and designers to build contents for them. But for simple requirements a very low cost […]

Room temperature display on big screen is a common requirement from industrial sector. Used in server rooms, PLC rooms, storage rooms and many other places in an industrial units. Traditionally seven segment displays of big size (say four inch height) were used. But now a days DMD (dot matrix display) have become so cheap and easily available

The 1K LCD Tinyfont project packs a variable-width 8-pixel font into 383 bytes and uses it from a 930-byte application that prints UART text on a Nokia 5110 LCD. This article examines the owner’s reported figures and the storage, buffering, and input-handling questions they leave open.

In this projects 8 different colors are displayed with the use of a RGB LED. The microcontroller that is used is the ATMega8. An RGB LED is a LED which has three LED’s integrated in one packaging. These LED’s have the colors red, green, and blue. Such a LED costs about 1 Euro. With these
Below is the schematic that shows how the IC is wired to the ATMEGA328 microcontroller and the 4 digit 7-segment display with comon cathode. Besides the MAX7219 you need only three other external components: two capacitors and one resistor. The capacitors are here to reduce noise signals and cannot be ommited. The resistor is used

Story Introduction This is my first Arduino project. My work was inspired by several maker projects that created Persistence of Vision Displays [2,3,4]. Persistence of vision (POV) refers to the optical illusion whereby multiple discrete images blend into a single image in the human mind and believed to be the explanation for motion perception in cinema and animated films [1]. The

How it started It started with the idea to make a technical proof of concept combining the Physical Web and WebBluetooth. The Physical Web is an effort by Google to allow interacting with “things” without fiddling around with installing apps or setting anything up. The basic idea behind that is that the “thing” broadcasts a

I’m thinking about a new project, something a little unusual but still with a rich history of information upon which to base the build. On Tindie, I found the RC2014 project which is a build of a Z80 platform but based on some modern components. That got me thinking. My next project must be a
