E&TC / ECE viva questions on this project
What is the aim of the Vehicle Movement Based Street Light Using PIC project?
Energy-saving street lights controlled by a PIC microcontroller. Sensors detect a passing vehicle and switch on only the lights around it, turning them off once it has passed.
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 Push buttons and switches provide manual inputs and the power switch. The PIC16F877A microcontroller with board handles the control logic, ADC readings and output switching. The DC geared motor provides the driving motion.
What are the features of the PIC16F877A?
It is an 8-bit RISC microcontroller with 8 KB flash, 368 bytes RAM, 33 I/O pins, an 8-channel 10-bit ADC, two PWM modules, USART, SPI and I2C.
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.
Why is a geared motor used?
The gearbox reduces speed and multiplies torque, so a small DC motor can move a vehicle or mechanism smoothly. Torque increases roughly by the gear ratio.
Why can't the motor be connected directly to the microcontroller?
A motor needs far more current (hundreds of mA to amps) than a controller pin can supply (about 20–40 mA). The H-bridge driver switches the motor current and allows direction control.
Why is a resistor connected in series with an LED?
It limits the current to a safe value (about 10–20 mA). Without it, the LED would draw too much current and burn out. R = (supply voltage − LED voltage) ÷ current.
Explain the block diagram of your project.
The input section senses the real-world quantity, the PIC16F877A microcontroller with board 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.
