Arduino Project Ideas for MTech graduates

Arduino Project Ideas

Arduino is basically an open-source Micro-controller board. It is based on Microchip ATMega328P Micro-controller developed by Arduino.cc. The board has sets of analogue and digital input/output (I/O) pins that can interface different expansion boards and other circuits. Arduino has 6 analog pins, 14 digital pins, and students of top MTech colleges in Jaipur can program using the Arduino IDE (Integrated development environment) via a type B USB cable. It also accepts the voltages between 7 and 20 volts and powered up by USB cable or a 9V battery.

The production files and layout for some hardware versions is also available for the students of top engineering colleges in Rajasthan. Arduino UNO version 1.0 board is first in the series of USB Arduino boards and reference model for multiple Arduino platform. The ATmega328 on the Arduino Uno offers pre-programmed with a bootloader which enables you to upload new code to it without the use of an external hardware programmer. It communicates via the original STK500 protocol. The Arduino UNO 1.0 does not utilize the FTDI USB-to-serial driver chip. Instead, it uses the Atmega16U2 (Atmega8U2 up to version R2) majorly programmed as a USB-to-serial converter.

Special Pin Functions

Students of best MTech colleges in Rajasthan uses each of the 14 digital pins and 6 Analog pins on Arduino Uno as an input or output, using pinMode, digitalWrite, and digitalRead functions. However, these pins mainly operate at 5 volts. Each pin can offer or receive 20 mA as recommended operating condition and has an internal pull-up resistorof 20-50k ohm. A maximum value of 40mA must not be exceeded on any I/O pin to avoid permanent damage to the micro-controller. It has 6 analog inputs, that is labeled as A0 through A5, each of which provide 10 bits of resolution (i.e., 1024 different values).

Additionally, some pins have specialized functions as follows:

1. External Interrupts - Pins 2 and 3 can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value.
2. Serial- Pins 0 (RX) and 1 (TX) can be used to receive (RX) and transmit (TX) TTL serial data. Students of top Engg colleges can connect these pins to the corresponding pins of the ATmega8U2 USB-to-TTL Serial chip.
3. PWM (Pulse Width Modulation) - 3, 5, 6, 9, 10, and 11 can provide 8-bit PWM output with the analogue Write () function.
4. SPI (Serial Peripheral Interface) - 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK) support SPI communication using the SPI library.
5. TWI (Two Wire Interface) - A4 or SDA pin and A5 or SCL pin support TWI communication using the Wire library.
6. AREF (Analog REFerence) - Reference voltage can be used for the analog inputs.

Project Ideas for beginners

A giant pixel display using Arduino

The LED pixel display uses LED strands to create texts, vibrant patterns, animated GIFs that enables students of private engineering colleges to frame, and hang right on their wall. The build relies on external software, called Glediator (free) that allow them complete LED matrix control, and the ability to create live or pre-recorded mixes of their LED animations.

For this, you also might need a10-meter strip of LED pixels, 5V 10A power supply, Thick wire, Ikea RIBBA photo frame, Glass frosting spray, and White paint.

Pulsating LED cube

If students of top engineering colleges in Jaipur are looking for something beautiful to build, the pulsating LED cube is the right choice. A single Arduino controlls LEDs via multiplexing and easy enough for beginners to make. Also, this project involves a good soldering practice, which is one of the essential beginner’s electronics skills they need to know.

For this, you might need a64 LEDs, Craft wire, Component wire, Crocodile clips, Scrap wood, and Drill.

Make your own Ambilight

It was developed originally for Philips TVs, the Ambilight features ambient lighting. That reacts to the images on your television screen. It is easy to recreate the Ambilight for any kind of screen. Cheap addressable LEDs cut the cost of this impressive build. And also write the component list for this project an individual have to pay reasonable costs upto 4500 INR. For this, you might need a WS2812B LED strip, and 10A 5V power supply.

Arduino-Powered Temperature Controller

Make your own Arduino temperature controller instead going for a commercial thing. This is an excellent beginner level project and a real-world application. For this, you might need a Temperature sensor, such as the TMP36, Relay or RC plug switches, Screw terminals. Also a Box to trap the heat, Heating/cooling element, and incandescent bulb with fixture (or both).

Arduino Traffic Light Controller

This project is a great introduction to Arduino programming for the students of MTech in Electronics and Communication Engineering. This can be easily done on a breadboard. The traffic light controller majorly uses a red, yellow, and green LED to re-create a traffic light on a breadboard. Therefore, it is an easy way to get hands-on with writing and editing code. For this, you also might need an Arduino UNO, A breadboard, LEDs red, green, blue, Resistors, Capcitors, connecting wires, and Power supply.

Simple Arduino Alarm System

A simple alarm system is used by the students of MTech Colleges in Jaipur uses a motion sensor to detect movement. Consequently, the LEDs flash and a high-pitched warning tone eliminated when an intruder detected. For this, you might need an Ultrasonic “ping” sensor, Piezo buzzer, LED strip light. And also a (Passive Infrared Sensor) PIR sensor (in case of motion detection).

Arduino RFID Smart Lock

An Arduino RFID smart Lock is complicated. However, it is more direct for the students of Private Engineering Colleges in Rajasthan to think due to a cheap and easy-to-use RFID reader. This project uses various new parts. Rather than starting from scratch, an individual can modify the code from the existing examples. So, this is an excellent introduction to multi-component devices with real practical uses. For this, you might need a Logic-level N channel Mosfet, 12v Power supply, MFRC522 module, and 12v Solenoid.
