  • 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.

  • 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.

    Arduino III Internet of Things Synthesis Lectures on Digital Circuits and Systems Editor Mitchell A. Thornton, Southern Methodist University The Synthesis Lectures on Digital Circuits and Systems series is comprised of 50- to 100-page books targeted for audience members with a wide-ranging background. The Lectures include topics that are of interest to students, professionals, and researchers in the area of design and analysis of digital circuits and systems. Each Lecture is self-contained and focuses on the background information required to understand the subject matter and practical case studies that illustrate applications. The format of a Lecture is structured such that each will be devoted to a specific topic in digital circuits and systems rather than a larger overview of several topics such as that found in a comprehensive handbook. The Lectures cover both well-established areas as well as newly developed or emerging material in digital circuits and systems design and analysis. Arduino III: Internet of Things Steven F.
