  • Arduino Sensor Beginners Guide
    Arduino Sensor Beginners Guide So you want to learn arduino. Good for you. Arduino is an easy to use, cheap, versatile and powerful tool that can be used to make some very effective sensors. This guide is meant to give you the basics of getting started with Arduino, and provide you with some basic code that will work with many sensors. The Materials To begin, you will need 1. An ARDUINO: I personally use an ARDUINO UNO V2, but there are many different types available. For our purposes they should all work the same so if you already have one, great. 2. A breadboard: Breadboards are named after cutting boards that early circuit enthusiasts used to hold their sensors. A breadboard is used as a place to hold your sensors, resistors and wires, and also serves as an easy way to connect things together. Breadboards come in all shapes and sizes. I would recommend something like this. This will cost you about 5 dollars online. 3. Wire: Wires are essential to Arduino. They are what allow you to actually connect your Arduino to stuff. Most small, hobby wire will work. All you need to make sure is that it is small enough to easily fit into the pins on your Arduino and breadboard. 4. A Sensor: Sensors come in all shapes and sizes. Most of the guides I have written use sensors similar to these, but don’t feel restricted to these ones. Many of them work pretty much the same way. Using Your Breadboard Different breadboards are set up in different ways.

  • Arduino Uno - R3 (Original - Made in Italy)
    Arduino Uno - R3 (Original - Made in Italy) The UNO is the best board to get started with electronics and coding. If this is your first experience tinkering with the platform, the UNO is the most robust board you can start playing with. The UNO is the most used and documented board of the whole Arduino family. Arduino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.. You can tinker with your UNO without worring too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again. "Uno" means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases. The Uno board is the first in a series of USB Arduino boards, and the reference model for the Arduino platform; for an extensive list of current, past or outdated boards see the Arduino index of boards.

  • Project Documentation
    Project Documentation Project Title: e-Glove Team Members: Harshit Rathore, Shubham Agrawal & Elle Atma Vidya Prakash Team Mentors: Rohit Agarwal & Divya Prakash Basic aim: To make a glove embedded with various sensors to detect hand and finger gestures, and implement those in many things, like playing games, giving presentations and many more. Motivation: We were having a look at previous year projects done under the electronics club, we saw many game controllers. So we thought of a game controller that can work for all the latest games, is full featured, and gaming looks more realistic using that. Inspired by things like Microsoft© Kinect™, Sony© Play Station™ motion controller, and many more such controllers available in the market, we came up with this idea. Theory: Sensors 1. Accelerometer: An accelerometer is a device that measures acceleration. When it is kept horizontal at rest, it measures 9.8 N/Kg downward. Whenever there is a tilt, a small component is left at the downward face, which can be detected. 2. Flex Sensor: The flex sensor is basically a variable resistor that reacts to bends. It changes its resistance when flexed so we can measure that change. The bend is only detected in one direction. TO read the data from the sensor, we need a fixed resistor (not changing) that we can use for that comparison (We are using a 33K resistor). This is called a voltage divider and divides the 5v between the flex sensor and the resistor. Microcontroller A microcontroller is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals.

  • Microcontrollers for IOT Prototyping – Part 2 V
    Microcontrollers for IOT Prototyping – Part 2 V. Oree, EEE Dept, UoM 1 Introduction • The Internet of Things is considered by many to be the 4th Industrial Revolution. • But unlike the first three, it is not a new technology. It is a new way of integrating existing technologies. As a result, it will not require a new kind of engineer. • Instead, to implement IoT, anyone hoping to embed IoT‐enabled capabilities in applications should gain a general understanding of the technologies. • Our intent is not to describe every conceivable aspect of the IoT or its enabling technologies but, rather, to provide an easy reference in your exploration of IoT solutions and plan potential implementations. 2 Introduction INTERNET OF THINGS 3 Sensor Selection Choosing a sensor (for example, a temperature sensor) for an IOT application may seem like a straightforward decision. However, selecting the right sensor involves taking many factors into account: Cost Supplier: How trustworthy is this seller? (Look at reviews from other buyers) Accuracy & Precision Availability: Some components can only be in large quantities. Measurement Range: What ranges will it work for? Power Consumption: Will it work with the power source I have? Sensor Selection Example: Temperature Sensor Texas Instruments LMT84LP Atmel AT30TSE754A‐S8M‐T Sparkfun DS18B20 Texas Instruments LM35DZ Cost: $0.91 Cost: $0.53 Cost: $9.95 Cost: $1.86 Accuracy: +/‐ 0.4°C Accuracy: +/‐ 2°C Accuracy: +/‐ 0.5°C Accuracy: +/‐ 1.5°C Range: ‐50°C to 150°C Range: ‐55°C to 125°C Range: ‐55°C to 125°C Range: 0°C to 100°C Voltage: 1.5V – 5.5V Voltage: 1.7V –5.5V Voltage: 3.0V –5.5V Voltage: 4V – 30V Availability: >10 Availability: >4000 Availability: >5 Availability: >10 5 IoT Development boards • IoT development boards enable makers to prototype their ideas.

  • A Short Note: Using Arduino Nano As a Substitute for Arduino UNO David R
    A Short Note: Using Arduino Nano as a substitute for Arduino UNO David R. Brooks, © 2018, 2020 For first-time and casual Arduino users, the most popular board option is the Arduino UNO. This board can be powered with a USB A-B cable when communicating between an Arduino board and the integrated development environment (IDE) that allows you to create and upload sketches, or once sketches are uploaded, by 7-12 V from some other DC voltage source, through an on-board 2.1 mm power jack to an on-board voltage regulator, when a sketch is already in place. There are many shields that fit on the UNO headers to add additional capabilities to the board – for example the Adafruit datalogging shield that includes both a date/time clock (set from your computer clock) and a microSD card module for logging data from sensors. There are alternatives to the Arduino UNO. The Arduino Nano is a small board that has the capabilities of a UNO in a much smaller and less expensive package, with a mini-B USB connector. These are available from allelectonics.com (ARD-20, $8.95) and other several other online sources, sometimes for less than $4 each. Arduino UNOs and compatibles are available at various prices from a variety of sources, some under $15. The only Nano I have tried, which is not an “official” Arduino product, is the one from allelectronics.com, so I can’t guarantee performance of any of the others. UPDATE: Because the NANO from allelectronics.com, and I assume other inexpensive online versions, is not an official version, it may be an older version that will not work with the default ATmega328P choice under the “Processor” menu.
