Mobile Phone Controlled Robot Car using G-Sensor and Arduino




In this article, we are going to Control the Robot Car through the G sensor of our mobile phone and you will be able to move the Robot just by tilting the Phone. We will also use Arduino and RemoteXY app for this G-Sensor Controlled Robot. RemoteXY app is used to create the interface in the Smart Phone for controlling the Robot. We will add the joystick in the interface so that Robot can also be controlled by Joystick as well as by tilting the phone.Mobile Phone Controlled Robot Car




G-Sensor or Gravity sensor is basically Accelerometer in Smart phone which is used to control the screen orientation of the phone. Accelerometer senses the X,Y, Z directions of the Gravitational force and rotate the Screen according to alignment of the Phone. Now days, more sensitive and accurate Gyroscope sensor is used in mobiles for deciding the orientation of the Screen. In our Project, Robot car will move, according to the direction in which phone is being tilted, like when we tilt the phone forward, then car will move forward and we tilt it down then car will move backward. This is same like when we play some car games in Mobile, they also use G sensor to move the car accordingly. Check the Video at the end, also check our other Robotics Projects here.

Required Components:

  • Two wheel robot car chassis
  • Arduino UNO
  • L298N Motor Controller
  • HC-06 Bluetooth module (HC-05 will work too)
  • Power supply or Cells
  • Connecting wires
