How the Android Streaming Micro Quadcopter with Obstacle Detection works
- 12 V power adapter / step-down transformer supplies the circuit; a regulator gives the controller and sensors a steady 5 V.
- The Camera module captures images or video for recognition and monitoring.
- The Ultrasonic sensor measures distance to an obstacle or a liquid surface using sound echoes.
- The Arduino Uno R3 reads the inputs, runs the decision logic written in C/C++ and drives the outputs.
- The Buzzer gives an audible alert.

E&TC / ECE viva questions on this project
What is the aim of the Android Streaming Micro Quadcopter with Obstacle Detection project?
A small quadcopter that streams live video to an Android phone and warns of obstacles. It is flown with an RC remote, while an ultrasonic sensor at the front triggers an alert when something is too close.
Explain the working of your project in short.
12 V power adapter / step-down transformer supplies the circuit; a regulator gives the controller and sensors a steady 5 V. The Camera module captures images or video for recognition and monitoring. The Ultrasonic sensor measures distance to an obstacle or a liquid surface using sound echoes. The Arduino Uno R3 reads the inputs, runs the decision logic written in C/C++ and drives the outputs.
What microcontroller is on the Arduino Uno and what are its key specifications?
The Uno uses the ATmega328P: 8-bit, 16 MHz clock, 32 KB flash, 2 KB SRAM, 14 digital I/O pins (6 PWM) and 6 analog inputs with a 10-bit ADC.
How is the camera image processed?
Frames are captured and processed with OpenCV: converted to grayscale, filtered and passed to a detection or recognition model that labels faces, objects or number plates.
How does the ultrasonic sensor measure distance?
It sends a 40 kHz pulse and measures the time until the echo returns. Distance = (time × speed of sound 343 m/s) ÷ 2. The HC-SR04 works from 2 cm to about 4 m.
What is the difference between an active and a passive buzzer?
An active buzzer has a built-in oscillator and beeps on DC. A passive buzzer needs a square wave from the controller, which allows different tones.
How is 230 V AC converted to 5 V DC for the circuit?
A transformer steps down the voltage, a bridge rectifier converts AC to pulsating DC, a capacitor smooths it and a 7805 regulator gives a steady 5 V.
Explain the block diagram of your project.
The input section senses the real-world quantity, the Arduino Uno R3 processes it according to the program, and the output section displays the result and drives the actuators. The power supply section feeds every block.
Which communication protocols are used between the modules?
The sensors give digital or analog signals read directly by the controller's I/O and ADC pins, and outputs are driven through transistor or relay drivers.
What is the operating voltage of the circuit?
The controller and most sensors work at 5 V (ESP boards and some modules at 3.3 V). The battery powers the board, and a regulator steps it down. Motors and relays get their own supply line so they do not reset the controller.
