The decorative Light Fountains are readily available in market as gift articles. Here the given project demonstrates how to operate it using TV remote (or any other remote of AC or Music System etc.)To make it Remote Operated it needs to be modified, inside its Internal Circuits and there is also a need to build one Simple Circuit using IR Sensor to sense IR Remote Signal. For your convenience kindly follow step by step process of how to do this with the help of given images.
Line Follower Robot
Line follower robot is a bot which can follow a particular line. Its a very good project to start with, for people who are interested in robotics and embedded systems.In this case, it will follow a black line on a contrasting white background surface.This bot comprises of a sensor section, driver section and a microcontroller to process the sensor values and correspondingly operate the motor driver section.Sensor section consists of IR sensors (2 in this case)Driver section involves the working of geared DC motors (via L293D IC)
