Bluetooth controlled robot using Arduino Nano

This Bluetooth controlled robot is operated simply using Bluetooth technology and also with the user command. The user has to install an app on his/her smartphone for controlling this robot. After pairing with a smartphone and Bluetooth controlled robot, the user can operate it via commands like forward, backward, right, left, and stop. Also, it has some extra features like forward and backward light indicators, a horn and speed control. These all commands are sent to the Bluetooth receiver from the smartphone. After receiving the command through the Bluetooth receiver, it sends the analog signal to the Arduino for decoding the code. And then after processing the right code the Arduino controls the motors, lights and horns of the robot.
