Using only an Arduino, a few resistors, a buzzer, and some bits of aluminum foil, you can create your own touch-sensor piano keyboard in just a few minutes! Using an Arduino Uno, you can create a piano with up to 18 keys; or with an Arduino Mega, you can get over 60 keys! Other Arduino

General purpose Arduino shield for self-balancing machines. Why did I make it? I previously made an Instructable in 2010 on how to build a self-balancing skateboard. http://www.instructables.com/id/Easy-build-self-balancing-skateboardrobotsegway-/ There are >500 comments on this and many express confusion setting up the balance sensors, software and electronics. On top of that, the analog output inertial measurement units

Cap’n ArrDrownHo! is the lovechild of Ardweeny and Boarduino and he’s here to commandeer your AVR ships. ArrDrownHo! inherits pros of both and cons of neither. Pick up an AVR chip and start prototyping instantly on a breadboard! Want to replace that costly Arduino in your project with a cheap AVR, but don’t know how? Use the simple plug-and-play

The Knock Box is a power strip with superpowers – it turns on your lamp whenever you knock on your nightstand. You get two outlets, individually controlled by knock-knock-knocking on a nearby hard surface. It’s great for hitting the lights when it’s pitch dark, but if an appliance can plug into the wall, you can toggle it!

The Pi is a fine little computer board, though not nearly as good as the Arduino when it comes to I/O capabilities. The beautifully-engineered Gertboard is a plug-in add-on that neatly overcomes this deficiency by giving the Pi access to an ATMega328, but it’s a very complex and expensive solution. An alternative would be to interface

I learned that one of my nieces had an interest in programming. She was working with robotics at high school and has a summer internship where they had Arduinos. I think she was able to borrow an Arduino to experiment with at home but every Maker knows that is not the same as having a

Today, I constructed a compact 3x3x3 LED cube utilizing an ATtiny2313 that I acquired around 2 weeks ago. Every time I wanted to update the LED cube with better patterns, I had to bring out my breadboard, reconnect everything following ATtiny2313 pin-outs, and upload the updated code. I proceeded to search on eBay and Amazon

Thanks to: http://jeonlab.wordpress.com/ Since I have read an article on todbot blog, I bought a couple of Wii Nunchucks from ebay. I don’t remember how much I paid for them, but it was much cheaper than buying the accelerometer breakout boards. With the nunchuck data reading library shared by todbot (Thanks!), I could easily read the accelerometer data

Arduino boards are great for prototyping. However they get rather expensive when you have multiple concurrent projects or need lots of controller boards for a larger project. There are some great, cheaper alternatives (Boarduino, Freeduino) but the costs still add up when you need many of them. This is a way, after about $25-$30 initial

This is a very low cost and simple Arduino GSM and GPRS shield. We use the module SIMCom SIM900 . It’s the cheaper module now available in the market. The module is not simple to mount by an hobbyst, so we use the Breakboard TDGGSM_900 that we presented here . You can buy the GSM
