BASICS OF THE SPI COMMUNICATION PROTOCOL

When you connect a microcontroller to a sensor, display, or other module, do you ever think about how the two devices talk to each other? What exactly are they saying? How are they able to understand each other? Communication between electronic devices is like communication between humans. Both sides need to speak the same language. In electronics, these languages are called communication protocols. Luckily ...

Excellent starter kit for people interested in learning about Arduino

Arduino is an easy-to-learn prototyping platform that lets you create interactive electronic projects. This Arduino compatible kit is the one I recommend to people who ask me how to get started. The reason I recommend it is because it's very cheap and it has a bunch of components that would cost a lot more if you were to purchase them separately. Two things it doesn't have, but should if you really want to ...

New flat transistor defies theoretical limit

A team of researchers with members from the University of California and Rice University has found a way to get a flat transistor to defy theoretical limitations on Field Effect Transistors (FETs). In their paper published in the journal Nature, the team describes their work and why they believe it could lead to consumer devices that have both smaller electronics and longer battery life. Katsuhiro Tomioka w ...

New electronic technique promises to double optical fiber communications reach

A new method of processing signals via fiber optic cables could vastly increase the distance at which error-free data is transmitted via submarine cables without additional signal amplification. As the technique is capable of correcting corrupted or distorted data being transmitted, it may also assist in increasing the capacity of all optical fiber communications. With demand for internet connectivity runni ...

The E-Taster Assistance System with Lab-on-Spoon and Lab-on Fork as ‘Electronic Tongues’

Subject: Daily life activities of food preparation can be challenging for consumers due to restricted skills and experience, loss of perceptive abilities (accident/aging) or due to product fraud and contaminations, commonly summarized under the term of food adulteration, which are exceeding human perceptive abilities in general. Thus, in our work the E-Taster-assistance-system for living assistance and food ...

Arduino based Electronic Queuing System

This is a Queuing System project requested by a clinic asistant which allows the doctor enter number from a keyboard and display it on a 32x16 LED panel. This project uses two Arduino, the first Arduino functioned as a SENDER which included a PS2 keyboard and a mini LCD for number input. While the other Arduino is functioned as a RECEIVER which will trigger a "ding-dong" tone and display number on the 32x16 ...
