General info

Second version of my robot that I made during highschool. It is controlled by Arduino nano board and Android app pared with HC-06 Bluetooth module. It usues the L293D push-pull driver to controll 2 Brushed DC electric motors. The robot is controlled by user through an android app.

Screenshots

Screenschots shows early version with Arduino Uno as a brain, but it was later replaced by Arduino Nano, mainly beceasue of it's small form factor. Current version with Arduino Nano on board:

Technologies

• Arduino IDE
• Bluetooth 2.0
• Android App Inventor

Parts needed

• Arduino nano
• L293D push-pull 2 channel motor driver
• HC-06 Bluetooth module
• Breadboard
• Breadboard jumper wires
• 2WD Robot Car Chassis
• Battery pack or other energy source. (I use 2x 9V batteries, one to power Arduino, Bluetooth module, and logic of the L293D, and the other one to power the motors)

Setup

Upload MARK_II.ino to your arduino and connect components as shown below (bear in mind that the HC-06 operates on 3.3V logic. Arduino can recive data from it, but transmiting data with 5V Arduino's logic requires additional 1k ohm resistor between Arduino RXD and HC-06 TXD): Connect with the HC-06 module with your's phone (connect to it like any external Bluetooth device e.g. Bluetooth speaker) From the P.D.R. I, app select the HC-06 module. That's it! You can now controll the robot.

Features

Driving forward and reverse in any direction, turning right and left.

Status

Finished, this exact setup is used in Mouse_III, but the android app is replaced by Desktop C++ program.
