Wireless Finger Drum using Arduino

I came across these Force Sensitive Resistors. I like them a lot and I wanted to do something with them, may be making them more usesable than standing on the breadboard. Few months ago, I created the pocket-sized  RevIO - Arduino Compatible and having fun with it since then. While playing with these two, I decided to put them together! To complicate things further, I wanted to use them wirelessly. So I add ...

Control Arduino Wirelessly with MATLAB

Been seeing few DIYs on how to establish a communication between MATLAB application and Arduino that is hardwired to PC. However, I haven't encountered anything that control Arduino via MATLAB wirelessly using the ENC28J60 compatible Ethernet shield. In this ible', I'm going to show the simplest way to control Arduino using MATLAB wirelessly. WHAT YOU NEED? 1) Arduino - You need a controller. I used Arduino ...

TI unveils its fastest 16-bit DAC, sampling at 1.5GS/s

Description   The DAC34SH84 is a very low-power, high-dynamic range, quad-channel, 16-bit digital-to-analog converter (DAC) with a sample rate as high as 1.5 GSPS. The device includes features that simplify the design of complex transmit architectures: 2× to 16× digital interpolation filters with over 90 dB of stop-band attenuation simplify the data interface and reconstruction filters. Independent com ...

Arduino and Xbee wireless setup

The Arduino Wireless shield allows your Arduino board to communicate wirelessly using Zigbee. This documentation describes the use of the shield with the XBee 802.15.4 module (sometimes called "Series 1" to distinguish them from the Series 2 modules, although "Series 1" doesn't appear in the official name or product description). A Simple Example You should be able to get two Arduino boards with Wireless sh ...

Wireless Robotics Platform with XBee Remote Control

I built a remote-controlled robotics platform using a 4WD mobile platform, an Arduino (Seeeduino Mega), an Adafruit motor shield, and two XBee radios for communication. There are also some super-bright white LEDs on the front for headlights. The point of the project was to show how an XBee radio can be used to send joystick sensor data without using a microcontroller on the remote. The vehicle is very easy ...

Arduino Wireless Animatronic Hand

BTW!!!!! This instructable is awsomeeeeeeThis is a very simple but at the same time a very hard project depending on your skill level. Lets get to building! What this is, is a wireless animatronic hand that doesn't need a computer to operate. The user wears a control glove and can control the animatronic hand precisely. Bellow are some pictures of the final product: Step 2: Control Glove Materials: Arduino ...
