Prizes worth INR 20,000 can be yours for the taking!

Maximum number of participants allowed has been increased to 4.

Perhaps, it’s all about the touch. Literally, in fact, as if you give a quick scan around, chances are that most devices near you will feature that great innovation – a touch-screen. HP brought it to the market, Apple immortalized it, and we, the consumers, simply can’t stop raving about it. Expect the touch-screen to invade into every aspect of your life, and soon, if the technological advances in that field are anything to go by.  The ways the touch-screen can be used are myriad and are limited only by your imagination and innovation.

Are you ready to do some touching and playing of your own?  In Q Contacto, we bring you the chance to prove your mettle with this fine invention, while trying to achieve that fine synergy between different devices such that they do your bidding.

The basic task would be to interface your resistive touch-screen with a microcontroller successfully. The first round will involve reading characters and figures (straight-lines only) from the touch-screen surface. Those skilled enough to pass through the first phase will find more daunting tasks in the second and third round, replacing those simple straight lines with more thought-provoking patterns . You might also be asked to configure your touch-screen – microcontroller assembly to perform some control-related tasks (such as motor speed control) after receiving the specified input, which has to be correctly identified.

Exciting prizes await the victors of this battle. Prizes worth INR 20,000 can be yours for the taking! So this Quark, go ahead, give this contest your best touch.

Details

Round 1:

Initially, all participants are expected to come out with a working combination of a touch screen and a microcontroller.
A reference length will be provided to the participants. Then, a line will be drawn on the touch screen by the judges. The task is to compare the length of the line drawn with the given reference length. An array of 1x5 LEDs will be provided. You are supposed to glow a number of LEDs proportional to the ratio of their lengths, i.e. all LEDs should glow if both the lengths are equal, only one LED should glow if the given line is just 20% as long as the reference line and so on.

Round 2:

Those skilled enough to pass through the first phase will find more daunting tasks in the second round, replacing those simple straight lines with more thought-provoking patterns. You might also be asked to configure your touch-screen – microcontroller assembly to perform some control-related tasks (such as motor speed control) after receiving the specified input, which has to be correctly identified.
