We wanted to build a model police car with working lights and sirens. Then we decided to add a motor and instead of using a switch to turn everything and off we used a photodiode. For our car the photodiode signal is a simple on off switch. If you want a more complicated device that will

A while ago, when I first started using Arduino, my first project was a 4x4x4 LED cube, I built it from a Guide I found here in Instructables, I didn’t know anything about programming, and little about electronics, yet I was able to build it and make it work, I didn’t know how it worked

My Lumix GH2 Micro Four Thirds camera not only shoots fantastic high definition videos, but with inexpensive adapters I can use it with older manual lenses that are cheap and often very high quality. I shoot a lot of performance videos for my daughter’s dance studio, and I use an f3.5 Nikon 28-85mm zoom lens because it provides a

This is, as the title says, an Arduino-based robotics platform, with its own library. The “standard” model comes with two back motors, two omni-wheels in the front, and a distance sensor mounted on the front. It also has breadboard space on top for adding whatever you want. It is intended to be autonomous, but one

I based this off of this really nice instructables.com post for building a water bottle boat, with some additions for obstacle avoidance and light-guided control. I used Arduino as a microcontroller, an ultrasonic sensor in the front, a few simple switches on the side of the boat, and a few light sensors on either side. See here for a

This is a step by step explanation of how to build a 5×5 LED cube using an arduino. I did this project for my undergraduate electronics class and it took me about 2 weeks to complete. Note: Apparently, some of the links for the supplies and code aren’t working, if you need them send me

THANKS TO CONCERNED VIEWERS, I HAVE LEARNED THAT THIS IS NOT SAFE AND SHOULD NOT BE REPLICATED. SO PLEASE DONT TRY THIS 🙂 THANKS TO EVERYONE WHO COMMENTED, I LEARNED A LOT I am not an engineer, just an experimenter and hacker and prototyper etc, so, thanks to people who know a lot more than

first what youll notice my grammer isnt the best 🙂 ok what youll need: 1 transister/mosfet that can handle the current for the water gun motor, this is the one i used – http://www.sparkfun.com/products/10213 – then a diode, i used this one – http://www.sparkfun.com/products/8589 – then a 10k ohm resistor, then a PIR, i didnt use this one but it should

Persistence of Vision (POV) Wands are a fun way to create interesting long exposure photographs and light displays. The wand consists of a single row of LEDs controlled by an Arduino Uno. When the wand is turned on it appears to be flickering in a random pattern, but if you move it quickly back and

What is a breathalyzer you may ask? It is a device for estimating blood alcohol content (BAC) from a breath sample. In simple terms it is a device to test weather a person is drunk or not. As the title suggests it runs on the Arduino. Our breathalyzer uses the MQ-3 alcohol sensor from sparkfun.
