Raspberry PI is a very smart single board computer and work with Raspberry OS (some kind of a Linux OS) and It can be use for many interesting projects. In this tutorial it is trying to interface a USB web camera to the Raspberry PI and use some image processing work on the grabbed web…
This is the second section of the raspberry pi weather station project. How to set up the Raspbian operating system and proxy settings are included in the section one. The main concern in section two is to give an idea about the General Purpose Input / Output ports (GPIO) in Raspberry pi. This section consists…
Most of the times the first lesson for microcontroller programming or embedded systems, is illumination of a LED or may be blinking LED using respective port pin. Most of the demonstrator boards starting from very simple ones to high end are having a LED or several with hardware which can make appropriate illumination. What makes…
Introduction What is Arduino? Use of microcontrollers has increased largely over the recent past in the field of electronics. Components in the microcontroller family are easy to work with due to their flexibility and simple methodologies. Building these into single circuit boards along with all the controller hardware and all the necessary controls such as inputs…
Introduction Conventional methods of displaying images or massage to public are using LCD display and dot-matrix LED displays. Propeller LED display is a special kind of device that project an image, text or time as if the images are floating in the air. Actually the floating images emerge by synchronizing LED’S blink to form an…
The purpose of this project is to build 3D LED cube controlling from PIC Microcontrollers. There are several types of LED cubes available with Microcontrollers. LED cubes, small 3x3x3 cubes, bi-color, RGB and mono cubes, amazing 16 x 16 x 16 RGB cubes. The cube described on this project uses a 5 x 5 x 5 matrix of single color LEDs. This is a good size to experiment with as the number of LEDs required at 125 keeps the cost down, doesn’t take too long to assemble and just fits onto a euro card sized PCB . In this design we are able to project simple 3D images in a pre-programmed sequence. This is done by means of lighting the required LEDs that form the particular image.
