LED Animation in Triangular Figure

Overview

The project aims to produce a variety of animations using the triangular LED arrangements.

Explanation

The Simple LED Animation Kit (SLAK) is used with the triangular arrangement of red, yellow and green LEDs wherein parallel connection is made for the 3 sides of the triangle. Only 6 bicolor LEDs consisting of 12 individual elements that are duplicated around the triangle are being controlled by the PIC16F628A microcontroller although there are 18 bicolor LEDs with 36 individual LED elements. This is because the SLAK platform can drive at most 12 LEDs which ends up to 6 bicolor LEDs. It will take 10 minutes for the animation sequence to be repeated using the current code.

A 2-level triangular base was used to build the project. Holes are drilled onto the small white triangle where the LEDs are wired and get connected to the proto board before practicing on the animations. A bigger triangle was made to handle the PCB which was placed behind the small triangle.

A 5V voltage regulator was used in the project to maintain the voltage since it is easily available and very common in the market compared to a regulated power supply.
