E&TC / ECE viva questions on this project
What is the aim of the Automated Pneumatic Powered Water Pump project?
A pneumatic system that operates a hand pump automatically. A pneumatic cylinder linked to the pump handle moves it up and down under electronic valve control, drawing groundwater without manual effort.
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 Arduino Uno R3 reads the inputs, runs the decision logic written in C/C++ and drives the outputs. The Mini submersible water pump moves water for irrigation, dispensing or cooling. The Solenoid lock locks or unlocks the door when energised.
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 pump switched by the controller?
Through a relay or MOSFET, because the pump runs at 12 V and draws more current than the controller pin can provide.
How does a solenoid lock work?
When current flows, the coil becomes an electromagnet and pulls the plunger in, releasing the latch. When current stops, the spring pushes the plunger back to lock.
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.
Why is mild steel used for the frame?
It is cheap, strong, easy to cut and weld and widely available. A frame of 25 mm square pipe is enough for most student models.
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?
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). A 12 V adapter 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%.
