This tutorial shows you how to use a Piezo element to detect vibration, in this case, a knock on a door, table, or other solid surface. A piezo is an electronic device that produces a voltage when it undergoes physical deformation from a vibration, sound wave, or mechanical strain. Likewise, applying voltage to a piezo

The blimp is controlled by a transmitter on the ground, operated by a human. There are three control levers– one for each motor, and one for the servo that rotates the axis they’re attached to. You push / pull to make the motors speed up or slow down; they’re controlled individually, it’s like driving a

I love to integrate devices which are not supposed to be integrated and this guide shows you how you can control an Android mobile using Apple’s Remote. (Who said Apple devices work only with Apple products 😉 ) Also this is my entry to the Sparkfun microcontroller context. If you like this guide, please do

This tutorial shows you how to read an Analog Devices ADXL3xx series (e.g. ADXL320, ADXL321, ADXL322, ADXL330) accelerometer and communicate the acceleration to the a personal computer. This tutorial was built using the breakout boards from Sparkfun. The adafruit accelerometer breakout board also works, though it must be wired differently. The ADXL3xx outputs the acceleration

The YaNis EOS controller is a device that allows you to wirelessly control your Canon DSLR from your Android phone. What’s really exciting here is that the Android interface allows you to change most of the camera’s settings (like Shutter Speed, Aperture Size, ISO, White Balance, Focus Position and others) from more than 20 meters

Recently, I decided I would like to attempt to make a passcode lock with my newly acquired Arduino Uno, but all the tutorials I could find made use of a modified keypad, something that not every Tom, Dick and Harry has lying about. I therefore decided to set out and make a version using only

This is an instructable for a bluetooth controlled Message Droid. I call it R2Blue2. It moves around and displays messages that you type using your phone or computer. Atleast it was supposed to. Due to many problems such as underpowered batteries and bad cable management I wasn’t able to extract the performance necessary. I will

Remote control is almost a standard accessory for most home applications, like TV, Hi-Fi, air conditioner and so on. Though remote control brings us leisure, when you really need it but have completely no clue where it is, or which one it is, you have every right to be pissed off. To solve the remote

Every summer, Qualcomm hosts a Battle of the Schools competition, which gives employees the opportunity to represent their home universities. This year, entries were to be homemade contraptions, and they were judged according to how cool they were perceived to be. Virginia Tech’s cannon project tied the University of Michigan for first place. The project

Sometimes you want everything in the program to stop while a given condition is true. You can do this using a while loop. This example shows how to use a while loop to calibrate the value of an analog sensor. In the main loop, the sketch below reads the value of a photoresistor on analog pin 0 and
