Introduction: Bluetooth Controlled Robot Using Android Mobile

In this project, we will show you how to make a Bluetooth controlled robot in a simple way and low cost.

Step 1: Bluetooth Controlled Robot Using Android

In this project, we will show you how to make a Bluetooth controlled robot in a simple way and low cost.

Step 2: Required Equipment

1) 1* Arduino UNO

2) 1* HC-05(Bluetooth module)

3) 1* l293D motor driver IC

4) 2* DC Geared motors

5) 2* 9V Batteries with clips

6) 1* Chasis

7) Connecting wires Few

Step 3: L293D Connections

* Connect pin 1, 9, 16 to the 5V of the Arduino these pins are enabled pins.

* Pin 4, 5, 12, 13 are Ground pins these were internally shorted so no need to connect all pins to ground. Connect any one of those pins.

* Connect

Pin 2 ---> Pin 8 of Arduino

Pin 7 ---> Pin 7 of Arduino

Pin 10---> Pin 6 of Arduino

Pin 15---> Pin 5 of Arduino

* Connect Pin 3 & 6 to a geared motor and pin 11 & 14 to the another geared motor.

Step 4: HC-05 Interfacing

Connect the pins of HC-05 to the Arduino UNO

-connect Vcc of HC-05 to the 3.3V of Arduino and GND of HC-05 to the ground of Arduino

-connect Tx of HC-05 to the Rx of Arduino and Rx of HC-05 to the Tx of Arduino

NOTE:-

1) Resistors are not mandatory.

2) Connect Vcc of HC-05 to the 5V pin in case not activated.

    Yes.
    The two motors of each side(left and right) have to be connected in parallel and the motor driver output should be given to the common points.

    Cool. I love diy remote control cars. It gets kids actually involved in making their own toys.
