Hi friends video show you how to control a robocar with Gravity sensor (G-Sensor) of your smartphone.
This car is controlled by Bluetooth, you can control with g-sensor or joystick control. Its very simple to make. Joystick can be operated in the normal mode by moving the slider with your finger.

Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Hardware Required:-
1. Arduino nano - 1
2. Bluetooth module HC-05 - 1
3. L293D (motor driver) - 1
4.Geared DC Motor s- 2 nos
5. Motor Wheels - 2nos
6. Front Wheel - 1
7. Power bank or Battery 9V - 1 or 2 as requires
8. connecting wires.- as required
9. Smartphone or Tablet - 1
10. LED - 1
11.330 ohm resistor - 1
Step 2: Projects Screen Shots:-
1. H-Bridge L293D - Motor Driver
L293D is IC which is commonly used as a H-bridge. There are also other IC’s like L298 etc. but in this tutorial, we will see how we can use L293D.
2. Bluetooth Module
HC-05 or 06 chip of Bluetooth module solderes to the module board containing DC-DC converter and level conversion RX and TX signals. Chip HC-05 needs power of 3.3V, but thanks to the converters, you can connect this module to the boards power by 5V.
RemoteXY is easy way to make and use a mobile graphical user interface for controller boards to control via smartphone or tablet.
