Arduino Tutorial - Lesson 5

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. A light switch is a simple device with two positions, on and off. 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.

Proto Shield for Arduino This is a design for an open-source prototyping shield for Arduino NG/Diecimila. It has tons of cool features, to make prototyping on your Arduino easy. Compatible with NG, Diecimila, Duemilanove and any Arduino-clone in the 'classic' shape and pinout.Reset button up topICSP headerLots of GND and +5V rails.DIP prototyping area makes it easy to add more chips.SOIC prototyping area above USB jack for up to 14-pin SOIC chip, narrow medium or wide package.Use 'mini' or 'medium' breadboard.Two 3mm LEDs with matching resistors.Extra 6mm button Ideas for use Larger breadboard for tons of working space! Tiny breadboard fits nicely on top.

Health Ancient Beliefs About Ganoderma Numerous legends provide a rich and extensive account about Ganoderma lucidum. It was said that in the early days in China, Ganoderma is very rare and hard to obtain. People during the time of the emperors considered it as a treasure greater than any jewel because they believe it provides an incredible source of energy and youthfulness. Furthermore, it was also mentioned that: 1.

DIY Projects, Inspiration, How-tos, Hacks, Mods & More @ - Tweak Technology to Your Will The format of this book is very different from the regular O'Reilly books. It is written by a geek for geeks. So it doesn't start with a smooth introduction about the basics. It seems to have a rocky start since a lot of assumptions is made about the reader. The diagrams also seem to be hand-drawn on napkins. Chapters 1 and 2 contain a bit of what the author self-admittedly confession to be "fluff". Arduino Tutorial: An Introductory Guide Update! Don’t miss our famous article:Â Top 40 Arduino Projects of the Web. Previously we introduced you to the Arduino and it’s awe-inspiring incredibleness.

Arduino Authors: TRONIXSTUFF In this article we go back to the past via the use of push-wheel/thumb-wheel switches with out Arduino systems. Here are some examples sourced from somewhere on eBay: For the uninitiated, each switch is one vertical segment and they can be connected together to form various sizes. MicroPython pyboard [v1.0] ID: 2390 - $44.95 The pyboard is a compact and powerful electronics development board that runs MicroPython. It connects to your PC over USB, giving you a USB flash drive to save your Python scripts, and a serial Python prompt (a REPL) for instant programming. Works with Windows, Mac and Linux.MicroUSB cable not included, but you can pick one up from the store!MicroPython is a complete re-write of the Python (version 3.4) programming language so that it fits and runs on a microcontroller. It includes many optimisations so that it runs efficiently and uses very little RAM.MicroPython runs bare-metal on the pyboard, and essentially gives you a Python operating system.

Capsella bursa-pastoris Description[edit] rosette (a), pointed leaves, flowers (c–e), pods (i, k) Like a number of other plants in several plant families, its seeds contain a substance known as mucilage, a condition known as myxospermy.[8] The adaptive value of myxospermy is unknown,[8] although the fact that mucilage becomes sticky when wet has led some to propose that C. bursa-pastoris traps insects which then provide nutrients to the seedling, which would make it protocarnivorous.[9] Uses[edit]

Cheap Arduino Wireless Communications I was looking for a way to handle wireless communications between two Arduino boards. Other options like Xbee or Bluetooth were going to cost $50 to over $100. Then I found a cheap RF transmitter and receiver at Sparkfun. Spooky Projects – Introduction to Microcontrollers with Arduino Spooky Projects is a set of four 3-hour classes in October 2006 hosted by Machine Project and taught by Tod E. Kurt. It is an introduction to microcontroller programming and interfacing with the real world using the Arduino physical computing platform. In the class, participants are shown and experiment with the Arduino’s capabilities and learn the basics of common microcontroller interfacing, such as: digital output to control lights and LEDs, digital input to read switches and buttons, analog output to control motor position or LED brightness, and analog input to read sensor inputs. From these tools all sorts of interesting projects can be created.
