Luca Dentella posted an example on his blog about creating a full-working dashboard for Arduino (charts and gauges) in Javascript, running entirely in a web browser without the need for a web-server. In this implementation, Luca uses the Arduino connected to an AM2302 sensor (DHT22) to get temperature and humidity values, which are then displayed on the dashboard. … Read More →
If you have ever tried to use sprintf() on an Arduino to convert from a float to a string, you will notice it doesn’t work.

The above function will most likely return a “?” to your char buffer. If you google around, you’ll see various functions that people have written to overcome this, but all of … Read More →
I have always wondered if it was possible to 3d Print with wax. IT IS and the following video demonstrates step by step how it’s being done.
Cellular made easy – Add GSM/3G support to your Arduino/Raspberry Pi/BeagleBone projects Chris Higgins at SparqEE has come up with a simple development board[CELLv1.0] that can give your projects cellular capabilities. So what can you actually do with it? Well,I can think of lots of things: Add an off-grid internet connection to your home automation system. … Read More →
Leap-motion is changing the way we interact with computers. It’s a small device that you plug into your computer that tracks the movements of your hands. Your gestures can then be turned into commands that can control applications or like in the video a robot arm. This might look like a very primitive design but if … Read More →
