Cypress Semiconductor Serial F-RAM (ferroelectric RAM) memories combine the nonvolatile data storage capability of ROM with the fast speeds of RAM. Serial F-RAM features a variety of interface and density options, including SPI and I2C interfaces, industry-standard packages, and densities ranging from 4KB to 4MB. Cypress Serial F-RAMs have three distinct advantages over other nonvolatile

WhatThis button pad is made using a PCB and other components manufactured by Sparkfun. It is driven by an Arduino Mega. Each button is nice and squishy and satisfying to press, and it has an RGB LED inside! I’ve been using it to control animations I’ve coded in Processing. The button pad sends a message

It used to be that upgrading a car stereo was fairly simple. There were only a few mechanical sizes and you could find kits to connect power, antennas, and speakers. Now, though, the car stereo has interfaces to steering wheel controls, speed sensors, rear-view cameras, and more. [RND_ASH] was tired of his 14-year-old system so

A collection of mini-spectrometer chips are arrayed on a tray after being made through conventional chip-making processes. Image: Felice Frankel Tiny device could replace expensive lab-scale equipment for many applications. Spectrometers — devices that distinguish different wavelengths of light and are used to determine the chemical composition of everything from laboratory materials to distant stars
Inexpensive chip-based device may transform spectrometry Continue Reading
All the versions of ultrasonic radars I have found for arduino devices (Arduino – Radar/Ultrasonic Detector, Arduino Ultrasonic Radar Project) are very nice radars but all of them are “blind”. I mean, the radar detects something but what is it detecting? So I propose myself to develope a system able to detects objets and identyfy them.
Electronic, Arduino enthusiasts and makers looking for a project to keep them busy this weekend, may be interested in a cool custom switch created by Dave Darko. That requires users to intermittently push a button in order to produce additional ‘on’ time and has been aptly named the, “Unhackable Arduino Switch Matrix.” The ‘unhackable’ switch,
As the popularity of Arduino boards increased, the demand for boards which comes embedded with some of the add-ons used with the Arduino increased. One of the most popular add-ons were the WiFi modules which are used to connect Arduino boards to the internet. Several boards were released by different manufacturers which used the Arduino
