The Arduberry is a simple and inexpensive way to bring Arduino shields to the Raspberry Pi. The device is a shield that slides over the Raspberry Pi and allows you to stack and use Arduino shields. The Arduberry requires no physical configuration to work with most shields. You can write Arduino sketches (programs) right on

In this article by Jack Creasey, author of Raspberry Pi Essentials, we will learn about the remote input/output technology and devices that can be used with the Raspberry Pi. We will also specifically learn about 1-wire, and how it can be interfaced with the Raspberry Pi. The concept of remote I/O has its limitations, for example,

This tutorial shows how to prepare your Raspberry PI board for debugging with JTAG. Using JTAG will allow debugging the Linux kernel using hardware like Segger J-Link. As Raspberry PI board does not have a connector with a normal JTAG layout, preparing the board for JTAG debugging involves finding the correct pins and wiring them

Amplifiers which run from 12V DC generally don’t put out much power and they are usually not hifi as well. But this little stereo amplifier ticks the power and low distortion boxes. With a 14.4V supply, it will deliver 20 watts per channel into 4-ohm loads at clipping while harmonic distortion at lower power levels

INTRODUCTION :- Monitoring vital signs and locations of certain classes of ambulatory patients can be useful in overcrowded emergency departments and at disaster scenes, both on-site and during transportation. To be useful, such monitoring needs to be portable and low cost, and have minimal adverse impact on emergency personnel, e.g., by not raising an excessive
