Introduction (Latest updates 29/3/2015) If you’ve read my early blogs you’ll know I do a lot of work with a pal of mine, Aidan Ruff. We had an R&D company for years and one of our products was a home control system which was plastered all over the UK tech press at the time and […]
Recently we have learned how to interface GSM Module with Arduino and send/receive SMS using GSM module. Interfacing any device with a micro controller is the first step to building a useful system or project with that particular device. In this tutorial, we are going to build a very interesting project – a Fire Alarm

The free ESD Suppression Selection Tool, from Littelfuse captures the environment where a circuit-protection device resides, and then runs a software simulation of the device. “This tool doesn’t evaluate our part as a standalone device because the part never operates as a standalone device,” said Chad Marak, director of semiconductor business development for Littelfuse. “It

This Instructable is for the build instructions for our new AVR ISP Shield Kit for Arduino. Its development owes a great deal to Instructables and our own community (particularly Nick!) and I hope to explain some of that along the way. Some astute Instructablites have asked. What does this do? Well essentially this shield can
So we’re always cooking up hot new hardware in the Grav Corp labs. Recently, we’ve been working on a project using a 128×64 OLED screen with the SSD1306 controller. Adafruit is a good source of these displays, with an excellent library written by Limor Fried. The Adafruit_SSD1306 library makes it simple to use these displays with

A little while back I released the very first version of ESPToy — a ESP8266 Development Board with a few useful on-board components like color LED, button, and temperature sensor. It has a built-in ATmega644 microcontroller, and pin headers for plugging in a ESP-01 through-hole WiFI module. Shortly after that, I discovered the Lua firmware
This is the 1st part of a series of 3 posts on the new ESP8266 microcontroller I only talk about a bare handful of new boards because most of them don’t pass my test: whether they’ll let me do something today that I couldn’t do yesterday. But every once in a while a new board, or a chip, comes along that

Embedded systems frequently use HD44780-type LCD displays as it is considered the most popular alphanumeric display controller. The interface comprises at least 14 pins: eight for data, three for control (EN, WR, RS), two for power supply (Vdd, Vss), and one for contrast (Vre). Configured in 8-bit mode, it requires at least 10 I/O lines
BLACKSBURG, Va., Jan. 22, 2014 – A Virginia Tech research team has developed a battery that runs on sugar and has an unmatched energy density, a development that could replace conventional batteries with ones that are cheaper, refillable, and biodegradable. The findings from Y.H. Percival Zhang, an associate professor of biological systems engineering in the
