E&TC / ECE viva questions on this project
What is the aim of the High Performance Hovercraft With Power Turning project?
A hovercraft that travels over land and water and can turn at full power. High-powered fans create the air cushion and thrust, and a microcontroller-based control with two batteries gives sharper turns than basic designs.
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 Water / rain level sensor detects the presence or level of water. The Push buttons and switches provide manual inputs and the power switch. The ATmega328P microcontroller with base board is the brain of the circuit: it samples the sensors, compares readings with set limits and switches the outputs.
Why is a microcontroller used in this project?
A microcontroller combines a CPU, memory and I/O pins on one chip, so a single low-cost IC can read sensors, make decisions in code and control loads without a computer.
How is water detected by this sensor?
The exposed conductive tracks are open circuit when dry. Water bridges them and lowers the resistance, and the controller reads the change as a level or as rain.
Why is a pull-up resistor needed with a push button?
Without it the input pin floats and reads random values. The pull-up keeps it HIGH until the button connects it to ground.
How does the HC-05 Bluetooth module communicate with the microcontroller?
It uses UART serial at 9600 baud by default. Data typed in the phone app is received by the module and passed to the controller's RX pin as serial characters.
How is a servo motor controlled?
With a PWM signal at 50 Hz. A pulse of 1 ms gives about 0°, 1.5 ms gives 90° and 2 ms gives 180°. The internal feedback potentiometer holds the angle.
Explain the block diagram of your project.
The input section senses the real-world quantity, the ATmega328P microcontroller with base board processes it according to the program, and the output section acts locally and sends the data or alert wirelessly. The power supply section feeds every block.
Which communication protocols are used between the modules?
UART (serial) for the GSM, GPS, Bluetooth or fingerprint modules and analog inputs read by the ADC for the analog sensors. Each protocol was chosen because the module supports it and it uses the fewest pins.
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.
How did you calculate the power rating of your system?
Using P = V × I for each load, adding a margin of 20 to 25%. Battery capacity is the energy needed per day divided by the battery voltage and allowable depth of discharge.
Is your system open-loop or closed-loop?
Closed-loop: sensors measure the actual position, distance or condition and the controller corrects the actuators until the target is reached.
