Remote Controlled Spy Car

Abstract

               We have seen bluetooth controlled car before this. Today we are going to see remote controlled spy robotic car. Here is the block diagram of remote controlled spy car. Applications of this car are this car can capture picture, can record audio as well as video using wireless remote controller i.e. using RF signals. Maximum range of this robotic car is 125 meters. It overcomes with limited range of infrared remote controllers.

Bluetooth Car

Abstract

            Today’s RC toys are controlled by a single dedicated (and often proprietary) controller.  We endeavored to develop a remote control car that would be controlled via Bluetooth wireless technology.  Since Bluetooth is a standardized and relatively reliable wireless protocol, we hoped to create a car controllable by any Bluetooth device.  Additionally, Bluetooth consumes low power and has a larger bandwidth than the standard 900MHz RF link which drives most toys.  This added benefit allows for sending of complex information from the car to the controlling device—something unseen in consumer grade RC cars.  Our computer-controlled Bluetooth car demo showed the feasibility and practicality of Bluetooth controlled devices while also revealing limitations in the amount of data transmission capable by commercially available Bluetooth options.

Thermometer using Microcontroller

Introduction

• This article is about a simple 0-100°C digital thermometer using Microcontroller.
• The circuit is based on LM35 analog temperature sensor, ADC 0804 and AT89S51 microcontroller.
