Glow Led-Technofest 2016: Task 1: New World (60 Mins)

This document outlines the tasks and rules for an LED-based competition called GLOW LED-TECHNOFEST 2016. The competition involves two tasks: 1) Creating a world map model using LEDs of different colors on a breadboard, and 2) A creative design task with no limitations. Rules specify no sharing of components and scoring based on correct use of LEDs, neatness, creativity, teamwork, and aesthetics. Guidelines provide LED wiring recommendations to not exceed maximum current and include proper resistors.

TASK 1: NEW WORLD (60 MINS)

LEDs, Resistors and Breadboards


will be used to form a WORLD
MAP. An assistive image is shown
on the right. Your structure should
be as similar, neat & clean as
possible. Only make the continents
using different colors. The choice of
colors is up to you but no more than
two continents should have the
same color.

TASK 2: NO BOUNDARIES (25 MINS)

Your imagination is the limit. Your task is to be creative and think like a team to be
the best in aesthetics. The beauty of your creation will win you this task.

RULES:

No Borrowing / lending / exchanging / for burned up LEDs. Points to be given on the basis of LEDs used
according to: Points=(LEDs used correctly) – (Leds burned if any). Points for Neatness, Creativity, Teamwork.
Presentation & aesthetics points. After ruling, the top team with the best structures would be awarded.

GUIDELINES:

Some good values to try:

As led forward voltages: Led current:


Red and green: 2.0 volts 20mA will work for most regular leds.
Blue and white: 3.0 - 3.5 volts Super bright leds can go from 30mA up to several amps.

LEDs can be placed in series providing some features are taken into account. The main item to include is a
current-limiting resistor. Without this your LEDs would burn.
A LED and resistor is called a string. A string can have 1, 2, 3 or more LEDs.

Three things must be observed:

1. MAXIMUM CURRENT through each string = 25mA.


2. The CHARACTERISTIC VOLTAGE-DROP must be known so the correct number of
LEDs are used in any string.
3. A DROPPER RESISTOR must be included for each string.

 For Blue and white LEDs use this combination. Only 3 leds with
100Ohm resistor (1/8 watt). The no. of parallel copies can be increased by yourself.

 For Red and Green LEDs use this combination. Only 5 leds with 47-
56Ohm resistor (1/8 watt). The no. of parallel copies can be
increased by yourself.
