LilyPad Arduino Stuffed Fox Toy

For a class on technology in libraries, I had to create a project that used the LilyPad Arduino, and I chose to create a stuffed animal that sings “Jesus Loves Me” while lights flash with the notes. I made a fox, but the pattern to which I’ll link can be used to make a raccoon as well. Step 1: Materials Electronic LilyPad Arduino Simple board - https://www.sparkfun.com/products/10274 5 white LilyPad LEDs - ...

Barista championship brewing stopwatch • Introduction using arduino

Upon the needs of the (2014) World Barista Championship Rules and Regulations, an adequate and precise time measuring is needed during the competition. These measurements are usually done by regular stopwatches with all the benefits (ease of use, common availability) and drawbacks (two stopwatches needed for each judge, as well as some mathematics are necessary for supervision). This Arduino-based stopwatch ...

Arduino browser based remote control (linux)

We have kids.  I love them to bits but they keep hiding the remote control for the satellite and TV when they put the children's channels on. After this happening on a daily basis for several years, and after my darling wife allowing me to have an Arduino for Christmas I decided that it was time to make something useful (in her eyes!) with the Arduino. So here we have the culmination of that: a web-based in ...

Lilypad Arduino Rocket Ship Cape

I am taking a Children and Technology course for my MLS this semester, and one of our assignments is to create a toy using the LilyPad Arduino development board. The LilyPad Arduino is used to create e-textiles that you can program to do various things. In this instructable, I will walk you through the process of creating a rocket ship cape that lights up and plays a scale. Step 1: Step One: Materials Sewin ...

Cookies adminitrator box [Electronics only] using arduino

At home the cookies disappear relatively fast. ¿Why? Well, principally because of me and my father. That's why my mother and my sister have to hide some to eat them later. It's embarrassing, I know, but it's because we are like "Oh, I want to eat a cookie", and some time later "I will eat another", and so on, and when we realize, we have eaten more than a half of the cookies. That's why I decide to make thi ...

Nursery Rhyme Hat using arduino

I created the Nursery Rhyme Hat for a class on youth and technology.  I'm new to instructables and e-textiles, so please bear with me! This is the first time I have used the Lilypad Arduino or any kind of soft circuit technology, so my coding is borrowed from several others (more on my code in Step 2). All in all, it was quite the learning experience creating this hat and I'm excited to share it with you! S ...

Gas Cap using an Arduino board

Since you've gotten into electronics, haven't you wondered if there is a fart sensor out there?  I sure did.  I discovered that if you use a methane sensor, especially the MQ-4, even at very low concentrations, it reads farts.  What if you combined that into a hat with an LED Bar Graph and a XBee?  Exactly.  The Gas Cap was made with that in mind.  For around $100, you can build your own Gas Cap, a human ga ...
