This is a very low cost and simple Arduino GSM and GPRS shield. We use the module SIMCom SIM900 . It’s the cheaper module now avalaible in the market. The module is not simple to mount by an hobbyst, so we use the Breakboard TDGGSM_900 that we presented in this post .

Back to homepage Analog computer 1 Analog computer is a type of computer that works with continuously changing variables, as opposed to digital computer that uses discrete values. Digital computers are almost always electronic or electromechanical devices, while analog types can use any continous variable: voltage, water flow , air pressure, length (slide rule) and other. Finished analog computer. While first modern computers were analog electromechanical differential analyzers in the 1930s, soon thereafter they were faced with competition from electronic digital computers.

Microcontrollers are well suited to display information on analog VGA monitors If you have been working on microcontroller projects for any length of time, then you know that it can be difficult to display a large amount of data, especially when it contains more than just plain text. There are limits to how much useful information you can display on a basic character LCD, or even a dot matrix LCD, since most have low resolution, no color, and a poor refresh rate. I came up against this problem when working on a robotics project that needed to display a color image captured from a small camera and decided to see how much effort it would take to create an image on a VGA monitor using only a microcontroller to "bit bang" all of the necessary signals. It took some time to learn how the five signals used on an analog VGA connection made an image appear on the screen, but the end results were much better than anticipated, providing a crisp 256 by 240 image on the monitor in 256 colors.

In this week's Gizmodo University: Discover Electronics, we're diving headfirst into the principle theories of electronics. The second of four classes in this series, "Volts, Amps, and Ohms" is presented in conjunction with Sparkle Labs. Good morning class, today we will be building off of last week's introduction to electronics theory. If you missed last class, please take a moment and review the last lesson , paying special attention to Chapter 5. Right then, let's get started.

So You Want to Use PWM, Eh? | Non-Lexical Vocables
Pulse-width modulation. It probably sounds a little confusing if you’re new to electronics. Kindof a word mashup, really. What do pulses, width, and modulation have to do with each other anyway? I remember first learning about PWM during my freshman year of college at RPI . I was in a pilot course called “Foundations of Engineering” under the excellent instruction of Professor Kevin Craig (whom I later worked for).

Arduino - HomePage
Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. The microcontroller on the board is programmed using the Arduino programming language (based on Wiring ) and the Arduino development environment (based on Processing ). Arduino projects can be stand-alone or they can communicate with software running on a computer (e.g.
OpenBench Logic Sniffer is an open source logic analyzer hardware design. It’s purpose is to provide a hardware platform for the SUMP logic analyzer at the lowest possible cost. This project started in the comments on a post . Initial circuit design , PCB layout , development , and testing continued in the forum under the code name Project SUMP PUMP .
