How to make a long range Android controlled car using Arduino?

 

Are you are a Robotics Lover?

 

Robotics is an interdisciplinary sector of science and engineering dedicated to the design, construction and use of mechanical robots. Our guide will give you a concrete grasp of robotics, including different types of robots and how they're being applied across industries.

 

What is a Robot?

 

A robot is the product of the robotics field, where programmable machines are built that can assist humans or mimic human actions. Robots were originally built to handle monotonous tasks (like building cars on an assembly line), but have since expanded well beyond their initial uses to perform tasks like fighting fires, cleaning homes and assisting with incredibly intricate surgeries. Each robot has a differing level of autonomy, ranging from human-controlled bots that carry out tasks that a human has full control over to fully-autonomous bots that perform tasks without any external influences. 

 

 

What is Android Mobile Controlled Robot?

This Arduino Uno based robot can be controlled via Android Mobile Application. This Project Application is designed by MOHD SOHAIL owner of this Blog page " Electronics is Fun ".

First Install the Android Application which is to be downloaded from the link below and then connect the Bluetooth Module with the application, then drive the RC car with the help of Mobile Application.
