Turbidity/Coloury meter

Introduction What is turbidity? Turbidity is an optical characteristic or property of a liquid, which in general terms describes the clarity, or haziness of the liquid.Turbidity is the measure of the amount of un-dissolved suspended particles that present in liquid, which are generally invisible to naked eye.The turbidity meter is used to measure amount of…

TIC TAC TOE

Introduction The objective of this mini-project is to develop a portable electronic tic tac toe board capable of playing with one player and a microcontroller or two players. Coming up with an algorithm and necessary hardware that would encourage players to play tic tac toe is critical. The finished product will be very user friendly…

Reflectometer

Introduction What is reflectance? Reflectance is a property of a surface which is equal to the proportion of incident light which it reflects or scatters. It describe about the surface’s nature. That is whether it is a rough or smooth one or it is a dark or light one. Reflectance is a very important fact…

Motion detecting twilight LED lamp

Introduction Motion detecting twilight LED lamp is design to turn ON & OFF the light in a room with the use of motion sensor. When a person go through the door inside to the room he or she may forgot to turn off the light when leaving the room. This happens very frequently in our…

Line Following Car

Introduction The line following car is a car that follows a black line on white surface. The idea to make a line following car is inspired when I saw some video clips of line following cars. The basic concept of the line following car is that the line is detected using optical sensors and according…

LED stroboscope

Introduction Stroboscope instruments are used for inspection and observation of moving parts by freezing or slowing down the action of an object. If a fast rotating or oscillating object is illuminated with periodic light flashes so they always hit it in the same position, the object will appear stationery in the eyes of the observer.…

Kitchen Timer

Introduction The project which is going to be introduced here is a Kitchen Timer which can be used with many of our day to day activities. A timer is a specialized type of clock. A timer can be used to control the sequence of an event or process. When the set period expires some timers…

IR remote controlled AC relays

Introduction Infrared (IR) remote controls are everywhere. Just about every piece of electronic equipment you can think of has one TVs, DVDs, hi-fi systems.Even the latest cameras have them!. This project is a 3 channel infrared (IR) remote controlled relay driver with power saving.  It works with 12-bit SIRC IR signals as used by Sony…

5x5x5 LED 3D visualisation unit

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.

8×40 LED display panel

In this project the main cope was to design low cost LED signage system as a display.Signage is any kind of visual graphics created to display information to particular audience. This is typically manifested in the form of give an idea in places such as streets or inside or outside of buildings.
