Digilent Inc.'sI/O Explorer board is a microcontroller-powered USB based input/output
expansion peripheral for PC computers. The I/O Explorer is useful for introductory
to intermediate programming classes to give students the ability to interact with
I/O devices outside of the PC.
USB Peripheral Devices
The I/O Explorer
provides RC servo connectors and a number of built-in I/O devices, such as switches,
push buttons, LEDs, rotary encoders and a speaker/buzzer. Also included are
Digilent Peripheral Module (PmodTM) connectors that allow access to and control
of devices external to the I/O Explorer. The board may be used either as a USB bus powered device or as a
self powered device. The board provides analog input channels and analog output
channels via on-board Analog to Digital (A/D) and Digital to Analog (D/A) converters.
There is also a Universal Asynchronous Receiver/Transmitter (UART) interface
for asynchronous serial communications.
The I/O Explorer can also be used as a microcontroller development board. It
microcontrollers, one having USB device capability. All the user requires is a
programming cable or in-system debugger to load firmware into the microcontroller.
Digilent supplies the firmware images needed to restore the I/O Explorer to the
factory configuration as a USB peripheral device if it has been reprogrammed
with user defined firmware.
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
ABI Research, a firm based in the UK that specializes in analyzing global connectivity and other emerging technologies, estimates there will be 40.9 billion active wirelessly interconnected “things” by 2020. The driving force is the usual suspect: the Internet of Things.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.
In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes. The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
