Arduino Tutorial - Lesson 5 We've done a lot so far, blinking lights, printing messages...all of that stuff is output: signals coming from the Arduino. The next step is to start playing with input, with the Arduino responding to outside events. In this lesson we will begin with the most basic kind of input, a push-button switch! You're probably familiar with switches, there's tons of them in your house. One kind of switch you use every day is a light switch. On the left, the switch is open and no current flows. (thanks wikipedia!) In this photo, you can see the internals of a light switch. Light switches are great but we need something smaller. These little switches are a 1/4" on each side, cost about 25 cents, and can plug directly into a breadboard. Normally, the two wires are disconnected (normally open) but when you press the little button on top, they are mechanically connected. Find 5 things around the house that have switches. Power up the Arduino and try pressing the button. Switch capability Fig 5.2 Fig 5.4
Talking Glossary of Genetic Terms Glossary Home | Text Version Designed to help learners at any level better understand genetic terms Guided by national science standards Explained by scientists at the NIH The National Human Genome Research Institute (NHGRI) created the Talking Glossary of Genetic Terms to help everyone understand the terms and concepts used in genetic research. In addition to definitions, specialists in the field of genetics share their descriptions of terms, and many terms include images, animation and links to related terms. Enter a search term or explore the list of terms by selecting a letter from the alphabet on the left and then select from the terms revealed. The Talking Glossary At the bottom of most pages in the Talking Glossary are links to help you get the most out of this glossary.
Francesco Giorlando :: Arduino I/O and Dynamic Graphing with R and the Manipulate library Recently, our lab has been working on a general timing measurement system to ensure that psychophysical timing of experiments is valid with different experimental setups ranging from calibrated lab CRT monitors to LCD projectors in MRI facilities. Essentially, we aim to have a portable and easy to use recorder of digital and analogue signals that can be analysed for delays in hardware and software as well as jitter in various parameters. Our sensors will be signals from eye trackers, photodiodes on displays and manual responses as well as synchronised triggers sent to and from MRI and MEG machines. The hardware we have chosen for this is the very affordable and powerful Arduino Due. The Due is a great match for general purpose I/O, it has: a 32 bit ARM microcontroller running at 84MHz96Kb of SRAM and 512Kb of Flash memory54 digital I/O pins12 analog inputs (at 12 bit resolution)2 DACs than can output audio at 12bit resolutiona USB connector compliant with USB host protocol
CY8CKIT - 050 PSoC® 5 Development Kit - Cypress Semiconductor The CY8CKIT-050 PSoC® 5LP Development Kit enables you to evaluate, develop and prototype high precision analog, low-power and low-voltage applications powered by Cypress’s CY8C58LP high precision analog device family. Additionally, this kit supports the PSoC Expansion Board Kit ecosystem as a compatible host platform. This kit is designed specifically for PSoC 5LP development, the PSoC 3 version of the same kit can be purchased from www.cypress.com/go/cy8ckit-030. This kit is designed for analog performance. Besides the analog, this kit is also meant to demonstrate the low power operation of PSoC 5LP. The Kit-050 has an onboard programmer/debugger (Cypress USB chip based), which lets you program the PSoC 5 without connecting Miniprog3. Kit Contents: PSoC 5LP Development Board LCD Character Display USB Cable Quick Start Guide Kit CD, which includes: PSoC Creator, PSoC Programmer, Projects and Documentation

Use Arduino with TIP120 transistor to control motors and high power devices Hello again. So you have a DC motor or lamp but no matter how you connect them to your Arduino they just won't work? Guess what, the Arduino is a brain that comes with small muscles. It can control LEDs and other low power nicknacks but not those power motors or lights you need for your next project. There are a few add-ons out there that you can buy such as power and motor shields for your Arduino. Or you can do it yourself for a fraction of the cost and double the pleasure. THE TIP120 DARLINGTON TRANSISTOR The TIP120 is an NPN Power Darlington Transistor. The TIP120 acts as a power broker or gatekeeper between the Arduino realm and the high power realm composed of the PC fan and its battery pack. The TIP120 has three pins. THE PROJECT In this tutorial, I will build a basic circuit in which I use an Arduino to control the speed of PC fan via the TIP120. THE SIDEKICKS ENTER THE 1K RESISTOR & 1N4004 DIODE & 1UF CAPACITOR! Then we have those DC motors. void loop() { }
PCB Fab Tutorial | Engscope A few years ago, I started experimenting with homemade prototype PCBs as an alternative to professionally fabricated PCBs from board manufacturing company. My company was flexible enough to give me some resources and time to explore the subject matter. What I discovered was that with a small initial investment, you can make reasonably high quality two sided boards. 1.
