We all have an invisible boundary around our body, which we call personal space. We certainly don’t like anybody piercing through this boundary. This personal space defender bow tie is a simple and elegant way to defend your personal space bubble from being invaded by close talkers. When somebody gets too close to you it flashes red lights for a few seconds. If the invader stays there, the lights keep flashing. The project uses FLORA, an Arduino -compatible wearable microcontroller board from Adafruit.

This shoe-integrated sensor system is supposed to serve as a walking aid for a person with impaired sight. It alerts the user about obstacles surrounding him. Based on the information received from multiple ultrasonic sensors attached to the shoes, an Arduino Mega 2560 board used in the project forms a virtual map of the surroundings. The user is alerted about any obstacle through a set of vibrating elements placed in the user’s trouser pockets.

Summer is at its peak and if you are looking for an indoor fun project, you might be interested to build this Laser Shooting Game. The project uses two Arduino mini boards; one for a target board and other for a laser gun. The target board has three IR photodiodes placed at the center to receive the laser beam. When the laser hit the target dead center, it is flat on the ground through a servo mechanism for a few seconds and rise up again for another shot. Here’s a video showing the game in action.

Arduino RoverBot receives commands from a TV remote

Posted on July 26, 2013 by R-B Leave a comment

A 15 year old Arduino hacker has written this instructable on building an Arduino RoverBot that is controlled through a TV remote. The Arduino-IRremote library is used to decode the IR signals received from the remote. The RoverBot is coded to drive forward and backward by pressing buttons ‘2’ and ‘8, whereas turn left and right using ‘4’ and ‘6’ buttons on the remote. To stop the RoverBot you need to press ‘5’.
