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.

Combination of Tableau and Python for Prescriptive Analytics with Tabpy

What is TabPy TabPy is a Python package that enables students of top engineering colleges to execute Python code on the fly and display results in Tableau visualizations. It results in the quick expansion of advanced analytics applications. The split approach provided by TabPy allows for the better of two worlds including class-leading data visualization capabilities that are mainly backed by powerful data science algorithms. Surfacing Python algorithms in Tableau allows users to tune parameters and evaluate their impact on the analysis in real-time with the updates of the dashboard. In order to make this possible, TabPy mainly provides an input/output approach to the students of best engineering colleges. Where the data is aggregated according to the current visualization and tuning parameters, both transferred to Python. The data is processed and an output is sent back to Tableau to update the current visualization. TabPy offers an approach that helps students of Engineering

What Are The Career Choices For Engineering Graduates In MBA

Best Career choices for engineering graduates in MBA Success does not need something more than the blind determination to reach the destination. The first and foremost thing an individual needs to do is to ascertain their career goal. And also, define the path to achieve it. Unfortunately, only a few people understand the complete process of unlocking the doors of opportunities. That is why; they land in the pool of failures. A similar process works for the engineering graduates. They (engineering graduates) do not have complete knowledge of what to do after completing their bachelor’s (BTech) or master’s (MTech) degrees in the engineering stream for better prospects in the future. Keeping this in mind, some reasons have been highlighted. That throw light on the significance of doing management after BTech courses or MTech courses. There are various options or choices for the students of  Top Engineering Colleges Rajasthan  in this industry. How MBA can be the best choice for B-T

What is Edge Computing

Importance of edge computing Edge computing is changing the way data is being processed, handled, and delivered from millions of devices across the globe. The explosive growth of internet-connected devices like IoT along with new applications that require real-time computing power, continues to drive edge-computing systems. Faster networking technologies, like 5G wireless, are allowing students of  Top Engineering Colleges in India  for edge computing systems to pace up the creation or support of real-time applications, like video processing and analytics, artificial intelligence and robotics, self-driving cars, etc. What is edge computing? Edge computing is an important part of a distributed computing topology in which information processing is located close to the edge. Here, things and people produce or consume that information. Basically, edge computing brings computation and data storage closer to the devices where it is being gathered, rather than relying on a central location th
