Ultrasonic Bluetooth Demo

The video shows the progress on an Android application used to control a small RC car with a servo motor for the front steering, and the usual DC motor for the back wheels. The app communicates with the car's control circuit through Bluetooth. The car's control circuit is mainly composed of an Atmega328, a L293 motor controller, and a slave Bluetooth module. The first application used for the p...

This short video shows an Android application receiving three bytes of data from an Arduino. The transmission is performed over Bluetooth. The three bytes have a range of 0-254, with 255 used to identify the first byte. The data being sent by the Arduino is a simple count, where the second byte is the first plus 10 and the third is the second plus 10.

A small demonstration of an application that can control a mobile robot's movement, as well as its head's movement. The communication between the robot and phone is done over Bluetooth (SPP - Serial Port Profile). Three bytes are sent to the robot. The first byte specifies the control method, either control the head or the robot's motion. The next two bytes either specify the speed and turning ...

A basic line follower rover that uses 4 line detecting sensors. It is controlled by an Arduino UNO and a L293 chip for the Tamiya's gearbox motors.

The video shows an mobile rover controlled by an Arduino. It detects obstacles in front of it by using an Ultrasonic sensor. Upon finding an obstacle, it looks left - right and turns in the direction of the farthest path. It does not stop turning until it sees a clear 15cm path in front of it. In case an obstacle is too close to its left or right, it backs up and turns away from the obstacle. T...

After seeing Mr. General (www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_2150580_-1), I decided to get the IR Sensor it uses to detect objects. I also purchased a couple of micro servos and a small tilt pan. After putting them together and seeing how well it worked, I tried to create my own Mr. General. This is what I ended up with.

This is a different version of the control circuit for the Bluetooth RC car. This was entirely assembled and soldered on a single PCB.

After finding this RC monster truck in the street, I brought it home and removed the original circuit. I removed the Arduino control circuit from my yellow Corvette and strapped it to the monster truck. The monster truck did have its original battery, but as expected it was dead. I ended up using a 9V battery for the demonstration, and it worked correctly. The Arduino motor shield does get very...

A modified RC car. It is controlled by an Arduino Uno and Arduino's motor shield. The communication between the phone and car is done through a Bluetooth module connected to the Arduino Uno. The Application is custom made. Front and Back lights were added to the RC car. To control the car, the phone sends an ASCII character to the Arduino. Depending on the character, the Arduino makes the motor...
