Sleep Tracking using an Arduino -Arduino for Projects. Background and motivation This project was motivated by two things: my almost complete inability to get out of bed in the morning, and my fondness for recording data from routine activities and making graphs with that data. My main problem with waking up in the morning is that feeling of grogginess along with an intense desire to sleep more. However, I’ve noticed that sleeping without an alarm clock, and just waking up whenever I wake up, helps.
And I’ve also noticed that sometimes when I wake up I am dramatically more refreshed than usual. Reading about sleep on the web led me to learn more about sleep cycles. “Studies show that the length of sleep is not what causes us to be refreshed upon waking. Here’s another paper of which I have since learned, that describes a “wearable interface for controlling the awakening time” based on this hypothesis:Biorhythm-Based Awakening Timing Modulation Goal The length of the sleep cycle varies for each person, and averages about 90 minutes.
Procedure. How to make your own Arduino board. If your are like me which I am guessing you are, then ever since you got into doing stuff with arduino you have wanted to make your own arduino board. You may be surprised to find out that making the prototyping board is actually very easy, and can have several advantages over using the commercially sold board. For one thing, All the components together cost a little over 15 US dollars as opposed to the $30 that the Uno board sells for. second, you may not actually want a board, but may simply want the atmega chip as the heart of the project, like if you are making a synthesizer or even a robot. In that case, you can just attach the hardware necessary to use the chip, and solder to the pins you need to use without needing the board. Another advantage is making shields. The only down side is that some parts of the arduino are kind of hard to build on perfboard.
Either way it is a fun and informative project. Build Your Own Arduino. Setting up an Arduino on a breadboard has become a process I have grown to love. Within a few minutes you can have a fully working Arduino platform to work with as you will see in this tutorial. There have been several occasions when I was at school and quickly put together one of these for testing some ideas for a project.
Plus it is just looks so neat with all the components laid out over the breadboard. Some of my Arduino Projects Whats is an Arduino? Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators.

Arduino power consumption. Powerconsumption: How long will i run this on a 9V battery? Operating an Arduino for a Year from Batteries | Alan Mitchell. The Arduino platform is a great product for producing a custom data collection system or controller. Programming is easy via a high-level language and a simple USB connection to the Arduino board. Incredible popularity has brought plenty of publicly available code and many add-on boards for interfacing sensors, storage, and wireless communications. However, most of my projects involve collecting data for multiple months, and access to mains power is often problematic. Battery-powered data collection is essential, but the Arduino quickly exhausts a battery when attempting to collect data for more than a few days.
This article describes a technique for extending the battery life of an Arduino for many months. The Arduino Uno board draws about 42 mA assuming no power draw from sensors or other components needed in your system. With a minimum supply voltage of 7 volts, the power consumption of the board is therefore 0.29 Watts. Basic Diagram of the Low Power Arduino System Like this: Arduino on Pearltrees. Teensy USB Development Board. The Teensy is a complete USB-based microcontroller development system, in a very small footprint, capable of implementing many types of projects.
All programming is done via the USB port. No special programmer is needed, only a standard "Mini-B" USB cable and a PC or Macintosh with a USB port. Update: Discussion / Support Forum Teensy 3.1 changes from Teensy 3.0 Teensy Loader Application Software Development Tools WinAVR C compiler. Teensyduino, add-on for Arduino IDE. Simplified USB Examples or Dean Camera's LUFA library. Breadboard Usage The Teensy is available with header pins, for direct no-soldering-required use on a breadboard, which can also be run from the +5 volt from the USB cable. The 128x64 Graphics LCD can be used with Teensy 2.0 and Teensy++ 2.0 and Teensyduino using this GLCD library. How-To: Shrinkify Your Arduino Projects. How-To: Shrinkify Your Arduino Projects.
Ever since I started making projects with the Arduino, I’ve had a desire to shrink them down to a single, small circuit board. One of my first projects, a customizable SLR intervalometer, was packed in a phonebook-sized cardboard box and used the Arduino Deumilanove connected to a breadboard with jumper wires. I brought the box out to Central Park at 5am to make a timelapse of the sunrise, but when I got to the park, I spent 20 minutes fixing the connections between the Arduino, the breadboard, and the components. Since then, I’ve explored a few different ways of shrinking projects down and making them more robust. For the intervalometer, I designed a circuit board that had female header pins to seat an Arduino Nano. It was a huge improvement on the design, but I knew I could do a lot better. I tried to teach myself AVR programming, but ran into a lot of snags along the way. When I came across this tutorial by MIT Media Lab’s High-Low Tech Group, I was elated.
