I run a NFS/NIS network under a combination of OS’s for the upper-division physics lab here at CSUC, and one source of irritation is when one machine goes down and nobody lets me know until suddenly that machine is absolutely necessary NOW! So I figured an Arduino, living in the machine on my desk, might […]
After seeing all the different instructables for Led cubes I was still left with a lot of unanswered questions. So after reading everything I could find this is what I got. I decided to make the instructable after building it…so ill try to recreate the process the best I can. This cube is different from others for
Lab Experiments involving the Heat Equation are usually one-dimensional exercises involving a copper pipe and a half-dozen thermocouples. But with DS18B20 “One-Wire” thermometer chips and an Arduino, it’s possible to measure hundreds of temperature values simultaneously. Here’s what my students Daniel Lund and Lawrence Lechuga and I came up with for 2-D temperature measurements. We

I was wandering the internet looking for a good Arduino tutorial on how to build a binary clock with seconds, but I could not find one. So now I am writing this for you to have a binary clock with seconds, minutes, and hours. What I did: -Because controlling 20 LEDs individually for this cube
I was googling around looking for some sort of device I could make using arduino and stumbled upon eshop with devices for visually impaired. What really shocked me was the price. I mean-I do realize that such sorts of devices are not really mainstream, but still, it was kinda high. So I decided to make
Universal clock suitable for visually impaired using Arduino Continue Reading
I have constructed a basic Arduino robot arm using 3 servos that cost me £15 in total plus a couple of hours in time to build and it’s very simple that I think anyone can replicate and build this. I already had the Arduino Duemilanove ATMEGA328, some foamboard, tools and glue. The robot arm has
Overview This is a guide to building an Arduino-powered clock that uses LEDs to display a 24-hour clock (hours and minutes) as binary digits, an analog meter to display the seconds, a switch to toggle between time-display and time-setting mode, and 2 knobs for setting the hours and minutes. This was designed from scratch, but
So the arm is wired into Arduino as per the previous post, Arduino: Modifying a Robot Arm and hopefully this has worked. In this next part I alter the Arduino sketch slightly and write the first Processing sketch to test control of the arm – video at the bottom. To control the robot arm we’ll
What is Clusterbot? He is a small, affordable, autonomous Arduino-powered robot. He can move, see, avoid obstacles, and makes a melodic chirping sound sometimes. Clusterbot was my first Arduino project, and I think he makes a great project for a beginner. While building Clusterbot you will learn how to use motor controllers, ultrasonic rangefinders and
I started with an idea of what I wanted to do from the beginning but one attempt after another I finally got to where I am now. This robot can be remotely controlled from anywhere in the world and driven around the house. I can see through it’s eyes. Here is a brief run down.
