  • 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.

  • Communication Protocols on the PIC24EP and Arduino-A Tutorial For
    Communication Protocols on the PIC24EP and Arduino – A Tutorial for Undergraduate Students A thesis submitted to the graduate school of the University of Cincinnati in partial fulfillment of the requirements for the degree of Master of Science In the Department of Electrical Engineering and Computing Systems of the College of Engineering and Applied Science By Srikar Chintapalli Bachelor of Technology: Electronics and Communications Engineering NIT Warangal, May 2015 Committee Chair: Dr. Carla Purdy Abstract With embedded systems technology growing rapidly, communication between MCUs, SOCs, FPGAs, and their peripherals has become extremely crucial to the building of successful applications. The ability for designers to connect and network modules from different manufacturers is what allows the embedded computing world to continue to thrive and overcome roadblocks, driving us further and further towards pervasive and ubiquitous computing. This ability has long been afforded by standardized communication protocols developed and incorporated into the devices we use on a day-to-day basis. This thesis aims to explain to an undergraduate audience and to implement the major communication protocols that are used to exchange data between microcontrollers and their peripheral modules. With a thorough understanding of these concepts, students should be able to interface and program their microcontroller units to successfully build projects, giving them hands on experience in embedded design. This is an important skill to have in a field in which configuring the electronics and hardware to work correctly is equally as integral as writing code for the desired application. The protocols that are discussed are the three main serial communication protocols: I2C (inter-integrated circuit), SPI (serial peripheral interface), and TTL UART (universal asynchronous receiver transmitter).

  • Using an I2C LCD with the Arduino Wire Library Scope and Audience
    Using an I2C LCD with the Arduino Wire Library Scope and Audience • This document gives a limited introduction into the use of I2C communications with the Arduino. – Specifically Single Master to single Slave, 7bit addressing, 100Kbps bus speed using the Arduino Wire Library with low to medium data signalling rates. • It is targeted at the amateur electronics/maker hobbyist. • Some rudimentary knowledge of electronics and software development would be an advantage when reading the following content. • It is not intended to be a definitive guide, more to give an outline and help the hobbyist create projects using I2C devices (specifically controlling an I2C LCD with PCF8574 in this case). – And more importantly to dispel some myths and feel confident in its application and use. • The examples cited are to support the use of the ‘LiquidCrystal_I2C_PCF8574’ library and should be read in conjunction with the ‘Arduino I2C LCD Driver Library’ Instructable. Note : The following information is true at the time of writing this document 14/10/15 What is I2C? • ‘I2C’, ‘I squared C’, ‘I2C’ or IIC stands for Inter-Integrated Circuit bus. • It is a standard created by Philips Semiconductors (now NXP Semiconductor) in the early 1980s ‘originally developed as a control bus for linking together microcontroller and peripheral ICs for Philips consumer products’1 across short distances. • In common parlance, sometimes known as ‘TWI’, Two Wire Interface by other manufacturers to circumvent trademarking issues. – There are however, some differences between I2C and TWI but are not in the scope of this document. • Bus speeds are2; Standard Mode 100 kbit/s (Sm), Fast-mode 400 kbit/s (Fm), Fast-mode Plus 1 Mbit/s (Fm+), High-speed mode 3.4 Mbit/s (UFm) – In general it is possible for different speed devices to occupy the same bus via clock stretching.
