How To Make a PC Control Robot

Do you ever tried to control your robot using your PC or laptop? Controlling a robot using PC or laptop is often being a fun for the student or hobbyist. Thus during this article you will be tend to learn how to control your robot using your PC or laptop. Here it is assumed that you know How To Send Serial Data From Arduino To Laptop or PC and How To Receive and Send Serial Data Using Arduino Board. Thus lets begin to making this awesome DIY hack today with us.

Here we use a L293D motor driver IC which is used for the controlling the rotation of the two motor connected to robot. Pin no 2,7,10,15 of L293D motor driver IC is connected to the pin no 9,8,7,6 of arduino board. Output pin 3,6,11,14  of the L293D motor driver IC is connected with the motor as shown within the Circuit Diagram Image.

For the connection of RX and TX read this article How To Receive and Send Serial Data Using Arduino Board 
NOTE:- Bluetooth Module should be removed while uploading the code from PC to Arduino board.

Code for PC Controlled Robot:

If you are beginner to arduino then download Arduino IDE from here How To Install Arduino Software On Windows. We use 9600 baud rate for the transmission of the data from PC/Laptop to Robot.Click here to Download the source code for PC controlled robot.

We can control the robot using the following instruction 
'8' = Forward
'2' = Backward
'4' = Move Left
'6' = Move Right
'5' = Stop

Fritzing: an Electronic Design Automation software

Image
Fritzing is an open-source initiative to support designers, artists, researchers and hobbyists to take the step from physical prototyping to actual product. We are creating this software in the spirit of Processing and Arduino, developing a tool that allows users to document their Arduino and other electronic-based prototypes, and to create a PCB layout for manufacturing. The complementing website helps users to share and discuss drafts and experiences as well as to reduce manufacturing costs. Fritzing is essentially an Electronic Design Automation software with a low entry barrier, suited for the needs of designers and artists. It uses the metaphor of the breadboard, so that it is easy to transfer your hardware sketch to the software. From there it is possible to create PCB layouts for turning it into a robust PCB yourself or by help of a manufacturer. Why Fritzing is needed Physical prototyping tools have come a long way and already allow non-engineers to quickly turn their ideas in
