Electrical Components The electrical components are the five motors and their associated circuits, the buttons, and the thermocouple. The Circuit We are controlling two stepper motors, three servos, a thermocouple, and a set of buttons using an Arduino. Our final circuit diagram looks like this: Building the Circuit 1. Stepper motors: The first step we […]

This is a submission about an Arduino in Action from Memphis, Tennnessee by Guy Cobb. Here is what he posted: Hello from Memphis, Tennessee. I wanted to send all of you at the Arduino headquarters this photo of my office with my Arduino “wallpaper” and Arduino earthquake detector. My Arduino project incorporates a Mega, Uno, […]

Dearest Spark friends, Our new hardware is here! In case you’re not feeling the length of this post, here’s the short version: Today we’re launching our new development kit, the Photon! It’s the spiritual sequel to the Spark Core (backwards compatible), and it’s faster, better, and cheaper. You can pre-order it now for $19, and […]

How Dottie Was Made My trusty Arduino (it’s red, a clone from Sparkfun, and it was on sale for $10) begins this journey to reverse-engineer a flip-dot board. I figure that if I can flip one single dot, using a shift register and a couple of transistors, then all I need to do is replicate […]

This lab most recently revamped by Edgar Berdahl and Wendy Ju. Chris Carlson, possibly Bill Verplank, and others have likely contributed. For this lab you need your Satellite CCRMA kit, a laptop computer with Ethernet adaptor to program it, and some headphones with a mini 1/8″ (2.54mm) stereo jack. You are also invited to bring […]

Introducing the Sweet Pea WiFi Shield Have you ever wanted to include WiFi functionality into your Arduino system but been scared away by the shear cost and complexity of it. Not to mention that you normally want to have a few other things in there such as maybe an SD card to be able to […]

I have been making my own Arduino’s on strip-board but recently bought some of the Evil Mad Scientist ATmegaxx8 Target Boards. While they weren’t designed as an Arduino board they are perfect to use as they have: – places for the crystal and capacitors (XTL and C1, C2) or resonator – place for the power […]

Overview The Arduino Ethernet Shield connects your Arduino to the internet in mere minutes. Just plug this module onto your Arduino board, connect it to your network with an RJ45 cable (not included) and follow a few simple instructions to start controlling your world through the internet. As always with Arduino, every element of the […]

Design: The rotational motion produced by the motor is transformed into linear motion through the use of a standard 1/2″-13 threaded rod as a lead screw. To account for angular misalignments in the rod the motor is not attached to it directly, but rather through a belt and pulley system. The ball bearing screen door […]
