Intro: 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.

STEP 5: Total Circuit Connections

STEP 6: Fritzing File

is it possible to connect 4 DC motors with 1 motor
drives?

varshinikv30 4 years ago

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.
