I love the movie Stargate and when I first saw it I immediately knew I wanted to make one of the super cool Horus guard helmets. I had sketched multiple designs over the years and figured out several different methods for building it but rejected them all for one reason or another- usually due to […]

*** I AM THIRTEEN. I REALLY ENJOY PUTTING TOGETHER THESE INSTRUCTABLES. PLEASE SHOW SUPPORT BY VOTING FOR ME IN THE LASER CUTTER CONTEST – http://www.instructables.com/contest/epilog3/*** I started thinking about this project a couple of months ago now. A laser tripwire that can log when the beam is broken and has the ability to take a

Here’s the Arduino version of a project to use the General Instruments (GI) SP0256-AL2 vintage speech synthesis chip to say “hello world”. I’d previously shown how to do this with a Basic Stamp 2. Here’s what it sounds like saying, “hello world” 20101215_164333.mp3 How it works, in short, is that the GI chip must be

Introduction Weather-band radio is an awesome public service provided in the US, Canada, and Bermuda. With hundreds of transmitting stations dotting the country, weather radio acts as the “voice of NOAA” (National Oceanic and Atmospheric Administration). In addition to spouting out weather forecasts, weather radio also implements a messaging protocol for emergency weather alerts called

We have written a tutorial for Rotary Encoders using a Microchip microcontroller but now would be a good time to make an Arduino UNO version. With a rotary encoder we have two square wave outputs (A and B) which are 90 degrees out of phase with each other. The number of pulses or steps generated

Description In this tutorial you will set up and turn on a single LED. Note that this code can actually be executed with just the Arduino and no other components as in Figure 5. If you notice, next to pin 13 is a tiny LED on the board. If you execute the code below, you
Arduino Leonardo AVR Development Board is a microcontroller board based on the Atmel ATmega32u4. It offers 20 digital IOs (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. The Arduino Leonardo differs

The Android phone that stays in your hand most of the time is useful in many other applications apart from Whatsapp, Facebook; appliances; monitor your health parameters. How it would be if it can control a Robot, which can assist in your daily work. With this project you can make a robot that can be
