Displaying Characters using Water

Our project “waterfall graphic print� can be described in one word as water speaks. In our project, we are using water as display element and develop a structure using AVR microcontroller, Solenoid valves, Triac-BT316 and MOC-3041.waterfall graphic print can be described in one word as water speaks. Characters which we display are the combination of water droplets and each character size is very large. We cannot display any word file or book using this technology. When water falls in air it creates the characters, so characters are very large and it takes time to read the whole word with proper attention Our project is used at many places like malls, colleges, company to display numbers and logos and different designs in air by using the water and to increase the value of the place. It is also used in chemical industries and dairy industries to mix the liquids in proper percentage by proper controlling of valves. So this project has many applications in general as well as in industries. It can be used at public places for enjoyment and also for publicity of any product. The most important part of this project is programming and we use AVR controller for programming and the software we used is BASCOM. Programming is very easy in this controller, so we spend more time in developing different logics instead of use that time in syntax. In this project, the microcontroller atmega16 is connected to PC or laptop through keyboard interfacing connection. So that the character can be displayed as soon as corresponding button is pressed on the keyboard. Keyboard interfacing will makes this project more user friendly.
