The ADXL203 Module  is high precision, low power, complete dual-axis accelerometers with signal conditioned voltage outputs, all on a single, monolithic IC. The ADXL203 measure acceleration with a full-scale range of ±1.7 g, ±5 g, or ±18 g. The ADXL203 can measure both dynamic...

The open-source Arduino Software (IDE) makes it easy to write code and upload it to the board. It runs on Windows, Mac OS X, and Linux. The environment is written in Java and based on Processing and other open-source software. Arduino has just launched its latest software version: IDE...

Ambiq Micro, the leader in ultra-low power solutions, launched  the Apollo 2 Wearables and IoT Platform. The Platform offers breakthrough power consumption of under 10 μA/MHz, which allows for double the battery life in wearable devices. Apollo 2’s performance will lead to longer...

Today I am going to discuss how to make a very simple DIY Breathalyzer using Arduino UNO and few external components. Ana Carolina designed this project as an instructable in instructables.com. This is a low-cost project and a useful one too. If you have no idea about what...

Brian Dipert discuss his experience replacing an iphone battery @ edn.com: About a week ago, in preparing to run some errands, I plugged my iPhone 4S into the charger in my car so that I could stream Pandora while I drove. Oddly, a "this accessory may not be supported" message...
