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. -

Realtime Capabilities of Low-End Powerpc and ARM Boards for Embedded Systems
Realtime capabilities of low-end PowerPC and ARM boards for embedded systems Alexander Bauer PHYTEC Messtechnik Gmbh Robert-Koch-Str.39, 55129 Mainz, Germany [email protected] Abstract With the stepwise integration of the Realtime Preemption Patches (RT-Preempt) into the Mainline Linux kernel and their support for architectures other than Intel and AMD, there are now a number of choices which board to use for a particular embedded realtime project running Mainline Linux. In order to select the appropriate processor and clock frequency, it would be desirable to have some generally applicable ranges of worst-case latencies that can be obtained using the various processor types and conditions. We, therefore, determined the internal worst-case latency of PowerPC and ARM boards running Linux 2.6.20 and above patched with RT-Preempt. The PowerPC-board (Phytec phyCORE-MPC5200B) was running at 266 and 400 MHz, the ARM board (Phytec phyCORE-PXA270) was running at 266 and 520 MHz. This article will provide the details of the various measurement set-ups, present the results and discuss them with respect to the design differences between PowerPC and ARM. 1 Introduction This paper presents the results of the latency tests and discusses the results with respect of the different In the embedded market there is a wide range of processor designs. processors to choose from. A processor is typically selected for a customer design because of it features, e.g. video interface and peripherals, and the clock 2 Latency Tests frequency. With the growing importance of Linux and especially realtime Linux for customer designs For the latency tests based on MPC5200 we used in the embedded market, it is also essential to choose the PHYTEC phyCORE MPC5200 board with 400 the right processor that will cope with the realtime MHz as a reference platform. -

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.
