What is I/O Expander? Input and output pins are very precious resources in small digital projects these days. Popular small micro controllers like the PIC, 8051, SX, BASIC Stamp, etc., may only have 8-to-16 lines of I/O available for use, while we typically have a need to drive LCD displays, LEDs and frequency synthesizers; and read A/D converters, keyboards, shaft encoders and more. Hardware interfacing is the name of the game, and you can never have too much I/O capability on a processor to handle all these tasks. Well, here’s a relatively simple project called the I/O Expander, or IOX for short, that will greatly ease that I/O pin crunch on your current micro controller project. At first it looks like a clone of the common “serial LCD” controller – but when you look under the hood, you’ll see an I/O processor that’s chock full of goodies that we use everyday in our ham applications: serial display driver, frequency counting, A/D conversion, keypad processing and digital potentiometer control.

Home Fritzing The Fritzing Creator Kit gives you a fast, easy and--most important--entertaining introduction to the world of interactive electronics. What do you get? The ultimate beginners book teaches you everything you need to know through a series of practical--yet playful--exercises. And that playfulness is the key! There is a paper robot who can turn his head; a fortune teller who is (of course) never wrong (no guarantee on that); a dinosaur who relays the news on your Twitter stream and a pong game on a big LED matrix display. The box is sturdy and gives you enough extra space to transport your projects. The Creator Kit is made in Germany--right here--in Berlin-Kreuzberg. We recommend this Kit from 12 years on. to our store Contents Impressions Detailed overview of the Fritzing Creator Kit Look inside the Booklet Find a lot more projects in our project galerie: online project gallery.

I/O Expander Expand I/O capabilities of small homebrew projects with"IOX" .. an I/O Expander Serial LCD + Frequency Counter + driver for A/D Converter, Keypad and Digital Potentiometer IOX SOURCE CODE | HOST SOURCE CODE (EXAMPLE) | Photo of IOX on Eval Board The IOX chip works great with the QuickieLab project board OVERVIEW The I/O Expander is a 28-pin SX microcontroller that is programmed to operate as a slave I/O processor to a host controller in your projects. DESCRIPTIONInput and output pins are very precious resources in small digital projects these days. Well, here’s a relatively simple project called the I/O Expander, or IOX for short, that will greatly ease that I/O pin crunch on your current microcontroller project. A Ubicom SX-28 is programmed to be controlled by the host microcontroller of your project using a standard asynchronous serial port running at 2400 baud, thus acting as the host’s “henchman” in performing various I/O functions.

Makey Makey | Buy Direct (Official Site) Non-blocking Operations on Arduino | No stinkin' library needed.... I'm using the term 'blocking' a little loosely here. In Arduino-land... I'm talking about delay(). // ... from the Arduino Blink Sketchvoid loop() { digitalWrite( led, HIGH ); // turn the LED on (HIGH is the voltage level) delay( 1000 ); // wait for a second digitalWrite( led, LOW ); // turn the LED off by making the voltage LOW delay( 1000 ); // wait for a second} "While it is easy to create a blinking LED with the delay() function, and many sketches use short delays for such tasks as switch debouncing, the use of delay() in a sketch has significant drawbacks. If you're new to Arduino, you might not realize just how badly delays can impact performance. If you need more mileage... structs + PROGMEM can be used to expand this approach to cover dozens of specialized operations without eating-up precious kilobytes.

Coding for your School | Kodable What is CodeHS? CodeHS is a comprehensive teaching platform for helping schools teach computer science. We provide web-based curriculum, teacher tools and resources, and professional development. By leveraging CodeHS’ web-based platform, teachers can access all of the tools they need to teach great middle school or high school computer science courses, all in one place. What is Kodable? Kodable is a complete K-5 curriculum taking students from learning to think like a programmer in Kindergarten to writing real JavaScript by 5th grade. Microcontroller Basics - Introduction | Homemade Circuit Designs Just for You One thing is great about microcontroller ICs, these are available almost in all parts of the globe and electronic retailers. Fundamentally microcontroller devices are popularly used in applications involving assessments of the surrounding environment and in similar electronics. You could find these devices being used for displaying a certain parameter, in motor control applications, LED lighting, sensors of various types such tilt sensor, accelerometer, velocity meter, data loggers, temperature controllers, keyboards etc. The primary understanding regarding microcontrollers could be obtained by referring to AVR Amega32 microcontroller which is so advanced that sometimes it’s called a computer within a chip. This device is assigned to carry out series of commands to form a program. The language of the program that you would be seeing here is C++. When it comes to MCUs, you get the facility of having the option of controlling and configuring all of its pinouts.

Creative Building Toys for Kids | K’NEX List of 39 Low Cost Linux Friendly Boards and Products Dmitry (omgfire), one of my awesome readers, compiled a great tabular list of Linux friendly boards and products that sells for less than $300 US (usually less than $200). This list includes technical details such as the processor, GPU, memory, NAND flash, connectivity, ports, supported Linux distributions… as well as availability and pricing information. There are currently 39 Linux devices in total. The vast majority are ARM based boards, but he also included 2 x86 products by VIA, but those are relatively pricey ($265 and up). Here’s a summary list with SoCs used, links to blog posts and product pages (if available), as well as price information. Raspberry Pi Board Model B Beaglebone Snowball PDK Lite The list is obviously not exhaustive (this would include hundreds of boards), but this still pretty good. You can download Dmitry’s PDF file that shows side-by-side comparison of 5 devices at a time.
