Cheap Arduino Wireless Communications. I was looking for a way to handle wireless communications between two Arduino boards.

Cheap Arduino Wireless Communications

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. Arduino Tutorial - Lesson 5. DIY Projects, Inspiration, How-tos, Hacks, Mods & More @ Makezine.com - 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. Labs / DC Motor Control Using an H-Bridge. Overview In this tutorial, you'll learn how to control a DC motor's direction using an H-bridge.

Labs / DC Motor Control Using an H-Bridge

To reverse a DC motor, you need to be able to reverse the direction of the current in the motor. The easiest way to do this is using an H-bridge circuit. There are many different models and brands of H-Bridge. This tutorial uses one of the most basic, a Texas Instruments L293NE or a Texas Instruments SN754410. If you simply want to turn a motor on and off, and don't need to reverse it, for example if you're controlling a fan, try the tutorial on controlling high current loads with transistors.

Don’t miss our famous article:Â Top 40 Arduino Projects of the Web. Martijn Thé – iPhone & iPad Development & Interaction Design » Interfacing an optical mouse sensor to your Arduino. In this tutorial I’ll describe how you can connect the optical sensor inside a cheap mouse to your Arduino and have it read out the x- and y-movements.

This will enable your Arduino to handle mouse input, detect surface movements, measure surface speed, etc. Materials This is what you need: Arduino board (any *duino will do) and the Arduino IDE.Optical mouse containing the PAN3101, ADNS-2610, ADNS-2083 or ADNS-2051 optical sensor. These sensors come in many mice sold today. Step 1 – Open up your mouse! The optical sensor and LED were covered with the black protective cap. Arduino-Python 4-Axis Servo Control. Tutorials / Using a transistor to control high current loads with an Arduino. In this tutorial, you'll learn how to control a high-current DC load such as a DC motor or an incandescent light from a microcontroller.

(:toc Table of Contents:) Parts You will need the following parts for this tutorial. Solderless breadboard 22-AWG hookup wire. Arduino Tutorial - connecting a parallel LCD. Using Relays with Arduino – Turning on the Lights. Warning!!!

Using Relays with Arduino – Turning on the Lights

This project deals with AC electricity which is dangerous if you don’t know how to treat it safely. You must treat electricity with caution. There are many books and websites about electrical safety procedures and if you’re not sure how to be safe you should read that information. The most basic advice I can give is always assume any exposed wires are live and touching them will hurt a lot at best and kill at worst.

Arduino Interrupts. Often when working on microcontroller projects you need a background function to run at regular intervals.

Arduino Interrupts

This is often done by setting up a hardware timer to generate an interrupt. The interrupt triggers an Interrupt Service Routine (ISR) to handle the periodic interrupt. Arduino Tutorial - Learn electronics and microcontrollers using Arduino! So, I get two or three emails a day, all basically asking the same thing: "Where can I learn about electronics?

Arduino Tutorial - Learn electronics and microcontrollers using Arduino!

" In general, most of these people have seen some of my projects and want to be able to build similar things. Unfortunately, I have never been able to point them to a good site that really takes the reader through a solid introduction to microcontrollers and basic electronics. I designed this tutorial course to accompany the Arduino starter pack sold at the Adafruit webshop. The pack contains all the components you need (minus any tools) for the lessons Follow these lessons for happiness and prosperity. A Multi-Protocol Infrared Remote Library for the Arduino. Note for Arduino 1.0 An updated version with 1.0 support is available on github.

Installation instructions are at the bottom of that page. Let me know if you encounter any problems. The World Famous Index of Arduino & Freeduino Knowledge. 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. In the class, a few simple project sketches are covered using the provided parts kit, under the theme of spooky animatronics for Halloween.

The class assumes no previous electronics knowledge, though it does assume a little programming knowledge. Class description at MachineProject Flickr photo set for the class Videos of projects Blog Posts. Tutorials / Setting up an Arduino on a breadboard. Arduino Diecimila / Burning the Bootloader without AVR-Writer. Arduino. My older son recently started school and needed his own desk for doing homework. I wanted to make something nicer than a simple tabletop with legs, and realized that I could also build in a bit of fun for when the homework is finished. Both my boys and I still had space travel on our minds from our summer trip to Kennedy Space Center. For this desk project, I decided to go with a NASA theme. I researched the Apollo Program as well as NASA's Mission Control Center, and designed my own console roughly based on those.

I say "roughly" because the actual Mission Control does more monitoring than controlling, and isn't awash in the whiz-bang rocket noises young kids appreciate. The desk resides under my son's loft bed (which I also built), and stays closed until the homework is finished: When playtime begins, the lid flips up to reveal the Mission Control console: As I mentioned in the video, I painted the underside of the lid with magnetic primer.
