Arduino Projects: Wireless Arduino

Long-time readers will know I’m not one to promote trendy marketing phrases and certainly ‘Internet of Things’ or ‘IoT’ is right up there with the best (worst) of them. But the concept behind the phrase is worth understanding as it drives the next generation of connected devices. Single-function or ‘embedded’ gadgets built from microcontrollers like the Arduino’s Atmel ATMEGA328P can now jump on-board the i ...

WIRELESS SENSOR ALERTS YOUR SMARTPHONE AS FOOD BEGINS TO SPOIL

While the stench of rotting food would cause you to stop from chowing down, chances are it became unfit for consumption some time before those funky aromas wafted through your nostrils. Chemists at MIT have been working on a wireless, inexpensive sensor that, among other things, identifies spoiled food early by detecting gases in the air. It then shares its data with a smartphone, potentially alerting users ...

GSM Based Wireless Notice Board

ABSTRACT: There are several places which require vital notice to be displayed like colleges, railway stations, share-market, restaurants, hospitals etc. Looking into the present trend of information transfer, it is seen that vital notice take time to be displayed on the displaying boards. This latency is not anticipated in most of the cases and must be avoided. The advancement in the technologies related to ...

Wireless Arduino Oscilloscope

In this guide I will explain how to use a Windows 8.1 phone, Arduino Uno board, and HC-05 Bluetooth module to build a wireless oscilloscope. The phone application has the critical functions of an oscilloscope, although the bandwidth is a measly 300 Hz. Still, if you want to see squiggly lines on your phone, it is a fun project. Today's phones have the ability to perform real-time signal processing. The chal ...

Simple Arduino Wireless Mesh

Build a low cost simple wireless mesh using arduinos and long range APC220 radio modules. Wireless mesh networks can handle individual nodes not working and are tolerant to environments such as forests and hills where data may not be able to go directly from one point to another. Step 1: How the mesh works This is a wireless mesh with a range of up to 1km between nodes. There are 16 nodes in each mesh, and ...

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 ...

Tutorials for Arduino Getting Acquainted with Arduino

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. The microcontr ...
