This example demonstrates one techinque for calibrating sensor input. The board takes sensor readings for five seconds during the startup, and tracks the highest and lowest values it gets. These sensor readings during the first five seconds of the sketch execution define the minimum and maximum of expected values for the readings taken during the […]
I was working on a project were I needed a cheap and efficient way to log the changing resistance of a sensor while simultaneously logging the temperature. This project is similar in many respects to the other data loggers on my site. Three prototypes have been built with the third one being a PCB. I […]
Basic information The DS1631 is a low cost, I2C interface digital thermometer popular in the maker community. Capable of providing 12-bit temperature readings over a -55°C to +125°C range. I have need for a digital thermometer in many of my projects and thought it would be nice to do a simple validation against a standard […]
Background I was in need of an affordable data logger for a project. I have access to MATLAB on all of my machines so it was an easy choice to build an Arduino based data logger that would easily interface with MATLAB R2014a. MATLAB is limited in both its sampling frequency (25 Hz) and its […]
Goals: The project goals are: Adjustable number of detents Adjustable foce threshold Software controlled damping Implementation: A brief overview: The team’s design utilizes several components: Arduino Leonardo Firgelli L16-50-35-12-P actuators (2x) FSRs (4x) TI L293D H bridge MSU Eagle custom PCB print The Arduino microcontroller is the heart of the team’s project.

In November 2014, we displayed our first completed project as a club, the Staircase Piano. The idea for the project was given to us by Professor Barry Brown before the club was even formed. Throughout the semester we worked towards putting the piano together for a final presentation before the end of the Fall 2014 […]
The proposed new LTD public transportation system uses people counters on the bus system to get an accurate measure of rider tendencies across different routes at specific times. Each bus will be equipped with two sensors which will generate numeric data no larger than 4 bytes of memory at any given time. The data will […]
A guide to getting started with the ESP8266 with the Arduino IDE This assumes that yo have a NodeMCU type board with the Silicon Labs CP2102 USB to UART Bridge. These boards are convenient because they can be connected directly to your computer for progamming and serial console. NodeMCU pin functions First install the Silicon […]
I wrote this one hot week in July 2010. I’ve been leaving my front door ajar, to get some air through the house. Probably not a very good idea. So I thought I’d hook up an Arduino to ensure that no one takes advantage of the door being unlocked. This essay isn’t meant, primarily, to […]
Introduction: Like many out there, I enjoy a good exercise session, whether it be indoors or outdoors. As part of that I purchased a Polar branded heart rate monitor, which came with a “Wearlink” chest strap and RS300Xsd receiver watch. The watch is able to do quite a bit of analysis on its own, in […]
