Arduino Barometric Pressure Web Server

This example shows how to use SPI communications to read data from a SCP1000 Barometric Pressure sensor, and how to then post that data to the web by using your Arduino/Ethernet Shield combo as a simple web server. Using the Ethernet library, your device will be able to answer HTTP requests by responding with just enough HTML for a browser to display the temperature and barometric pressure values outputted ...

NES in a Cartridge using Arduino

Have your ever seen any of "Ben Hecks" portable console builds? Well if you haven't, he often uses these Chinese Famicom clone consoles. These cloned consoles are often times refered to as NOAC's, meaning NES On A Chip. They are called this because they are a fully functional Nintendo Entertainment System literally on one chip. The best part about the NOAC is that they include a 60 pin famicom game port, wh ...

DIY $5 USBTinyISP

Dear Adafruit, Sparkfun, Radioshack, and hobbyist companies of the like, I'm a high-schooler with zero dollars in the bank. I can't really afford to buy a $60 Arduino from RS when I could buy it for $15 on ebay, from Shenzhen or Hong Kong. I understand that I am hurting your business by not buying your products, but by doing so I educate myself and others. I just want to say thank you for teaching me how to ...

Create an Internet Connected Pill Dispenser

The P.I.L. Box - A Better Medication Reminder System Studies show the consequences of patients not taking medications according to doctor's orders can be serious, especially in older patients.With today's low cost micro-controllers and sensors (and the incentive of the Radio Shack / Instructables Micro Controller Contest) I thought there must be a better way to ensure my elderly relatives are taking their m ...

Android talks to Arduino

This project slightly modifies the Google Android sample app called "Bluetooth Chat" so you can type a message in the Android app and that same message will appear on an LCD attached to an Arduino Uno. Functionality:  Android  talks to Arduino 1. Run the Android "Bluetooth Chat" sample app (after we modify the app in this instructable).  Type a message in the app's text box and press the "send" button.  The ...

Make an Emoticon Jacket with LCD screen using Arduino

Concept: I would like to make a jacket that has a small LCD screen to create subtexts for interpersonal human interaction. The user would use a limited "keyboard" with force sensors and buttons under soft silicone keys to create computer textual subtitles to human interaction (textual emoticons, ie: :P). The dichotomy between personal interaction that occurs in physical space and that which occurs on a comp ...

Offline Switchers Come in Tiny Packages

When engineers consider offline switchers for systems ranging from telecom and datacom equipment to PCs and industrial supplies, they mainly think of bulky AC/DC front-end solutions in a variety of forms such as bricks, modules, and open-frame. However, there are many applications where offline switchers powered by AC mains are needed in small packages or must occupy a small space on the motherboard. Some e ...

Create Interactive Electronic Instruments with MaxMSP

This Instructable is part 3 in an Intro to MaxMSP series I've just finished teaching atWomen's Audio Mission in San Francisco.  Part 1 is an introduction to MaxMSP and MIDI, part 2 is intermediate Max and Audio, and this Instructable is all about interfacing MaxMSP with hardware. I recommend at least skimming over my last two instructables before diving into this one, many of the example patches I use in th ...

Make another Arduino LCD shield

In this tutorial we make an LCD shield for using 20 character by four row LCD modules with Arduino Uno. Updated 18/03/2013 In this article you can follow the process of making another LCD shield for the Arduino Uno or compatible boards. In the past (which explains the word another in this title) I made a 16 x 2 character LCD shield, however it was not backlit, nor large enough. Recently I acquired a 20 x 4 ...

A simple Arduino-based tachometer

Chris, from PyroElectro.com, proposes a comprehensive tutorial on how to make a simple, yet effective, Arduino-based tachometer. The circuit is very simple: an IR led is coupled with an IR phototransistor to detect possible interruptions of the light beam, while the Arduino is responsible to calculate the time interval between two such events. Finally, a LCD is used to display the current RPM to the user. T ...

Arduino ultrasonic range finder

Hello, in this project i want to show and explain you a range sensor with ultrasonic and a 20x04 lcd screen. I wrote the code for this project myself and added lots of comments, so that everybody can understand it and use it for other projects (maybe a light range sensor?!). It is easy to build and much more easier to program, it just requires a few cheap parts and can run on battery, for a portable rangefi ...

RGB LED Skate Light

I like to go skating every week but I noticed that the my skates weren't cool enough so I decided it was time for some lights! I installed these lights on my Dad's skates as a thank-you present for taking care of the pool for us :D. Thanks Dad! The project is just two RGB LEDs controlled by a ATtiny2313. Very cheap and easy to make with GREAT results! Please give it a vote for the Microcontroller and I Coul ...
