Reverse Engineer a Cheap Wireless Soil Moisture Sensor

At the Maker Faire this year I got lots of questions about soil moisture sensors, which I knew little about. So I started seriously researching the subject. I found a few different soil sensors, learned about their principles, and also learned about how to make my own. In this blog post, I will talk about a cheap wireless soil moisture sensor I found on Amazon.com for about $10, and how to use an Arduino or ...

ARDUINO with XBEE- WIRELESS SETUP DEMO

This video describes how to configure two Series 1 XBEEs using Arduino UNO board.The ways of making 2 way communication is also tested on Wireless mode. Overview The Xbee shield allows an Arduino board to communicate wirelessly using Zigbee. It is based on the Xbee module from MaxStream. The module can communicate up to 100 feet indoors or 300 feet outdoors (with line-of-sight). It can be used as a serial/u ...

keyMote: a simple wireless remote for computers

Note: this post about an electronics project has been sitting as a draft since 2011 so some of its content might appear outdated. Regardless, I’ve been using the device since then so I figured I should commit it to posterity. To my computer, its simply a USB keyboard, nothing less, but to me its a remote I can use on any platform with no line of sight. I decided to name it the keyMote. Sounds a bit odd to m ...

Wireless nunchuk controlled animatronic doll using Arduino

This instructable will attempt to show you how to make an animatronic doll controlled by a wireless nunchuk. This doll can only move its head though. I'm sure there are plenty of people out there who can take this and expand on it and make it much better, and I encourage that completely. :) This instructable will focus more on the coding and wiring than on the building. Since the doll you use for this proje ...

The Arduino Wifi Shield is now available

The Arduino Wifi Shield is finally here! We’ve been working for a while on this new wifi shield for Arduino that is quite different from what you can find already on the market. Instead of just getting the usual pre-made module we decided to build a product that would encourage hacking and modifications so we decided to use an AVR32 processor running an open source version of TCP/IP and the WIFI software st ...

Wireless Altoids Display using an Arduino

This Instructable will show you how to modify an Altoids tin for a wireless 2x16 character display. Using an Altoids tin was inspired by the need to have a small yet protective enclosure for a pair of Xbee modules recently bought from Sparkfun. I purchased the Xbee Pro modules with external antenna for the extended range the setup provides (useful for future projects). Then I realised I would need to mount ...
