Arduino Pet Robot (Bluetooth)

Story

The first thing about this robot this is totally awesome and cool.

Meet My RoMo a cute Arduino Bluetooth Pet Robot with cute attitude. The Robot can enjoy with a sense of Bluetooth .If the light automatic Off then its On the own Flash Light. See more on RoMo ,it can run upto 1 hour nonstop depended in your battery life .This platform is running in my Arduino Nano and also can run in Uno but cannot work in Pro Mini. The speed is high then I deserve to play upto 300 rpm,Its not a robot ,its also perform like Bluetooth RC Car. The cuteness of RoMo starting more another like play music.

Parts For This:

Arduino Nano

L293d

HC-05

4 ohms Speaker

LDR

7.4v Battery

BO Motor

5V Module

10k Trimpot

220 ohms Resistance

Caster Wheel

Make A L293d module:

L293D is a typical Motor driver or Motor Driver IC which allows DC motor to drive on either direction. L293D is a 16-pin IC which can control a set of two DC motors simultaneously in any direction. Dual H-bridge Motor Driver integrated circuit (IC).

Schematic:

Note: HC-05 not in diagram you must connect on pin 0 and 1
