Hi, friend very sorry for the delay as I was in a business trip in Taiwan. Below is the step by step process of making the easy Gesture control robot using a single Arduino and any smart phone.
In this project we have used an Arduino UNO board ( https://amzn.to/2CwJxfZ )for robot, which was connected to an smart phone ( it could be your old smart phone too) over blue tooth ( Bluetooth module you can buy from https://amzn.to/2QUPd8V) . The firmware loaded in the robot can recognize the commands coming from the mobile app and takes necessary logic action for different kind of movements. Necessary circuit were soldered on a single vero board and were use as shield.
Search “Accelerometer robot” in play store and load the 3rd party app from Techmania ( Link: https://play.google.com/store/apps/details?id=appinventor.ai_jawad360s.MBT_Robo )
This app has many bugs but it will work. One of the bug is once you connect the robot is does not show the robot is connected. However you can see the LED of HC-05 Bluetooth module’s
Will blink slowly on successful connection.
The App sends specific character value if the X or Y tilt value is more than ± 20 deg.
Here are the command its sending and the prort setting we are doing for different movements like forward, backward, stop, left turn, right turn.
Forward movement:
App sends Char 2 ( dec 50)
On receiving 50, Arduino set at port as below;
analogWrite(5,150); // PWM pulse to reduce the speed of the motor)
analogWrite(6,0); //Motor-1
analogWrite(10,150);
analogWrite(11,0); // Motor2
Backward movement:
App sends Char 8 ( dec 56)
On receiving 50, Arduino set at port as below;
analogWrite(5,0);
analogWrite(6,150);
analogWrite(10,0);
analogWrite(11,150);
You can download the Arduino firmware and can see different port settings:
The app send following char:
STOP : App send char 5 ( Dec 53)
Left Turn: App send char 6 ( Dec 54)
Right Turn: App send char 4 ( Dec 52)

Make your own robot and have fun.
