After the success of small modules USB – I / O converters – PUSBIO with MCP2200 circuit intended for development and small batch production, which we introduced in Article MCP2200 USB module and I / O , and recently introduced software for USB I / O modules , now the company introduces new modules Pandatron with relays and optocouplers.

Small Arduino compatible USB host board. Take control of your Android phone or other USB device in your next project.
This project began the day I saw the Google IO 2011 talk about the new Android Accessory Development Kit (ADK). I had never seen or used an Arduino before. I had written a few Android programs but something about being able to connect custom hardware to my phone inspired me to start this long trip down hardware lane. Specifically, I was inspired to create motorcycle navigation software knowing that I would be able to create a remote control for my phone that would allow me to control the software with gloved hands. I finished the navigation software a few months later, and it has been a great success. This board has allowed me to complete that project; I now have a remote control attached to my motorcycle.

The micro-sized, Arduino enabled, usb development board – cheap enough to leave in any project! Erik Kettenburg writes:
The Story: We set out to build a little brother to the wonderful Arduino line of development boards – we were tired of leaving our valuable Arduino’s behind in projects, or worse, ripping apart old projects to build new ones! We also felt the Arduino was too big and powerful for many projects where we only needed a few pins, or an SPI or I2C bus. And so the Digispark was born! To us, the best things about the Arduino is the community, the easy of use, and the IDE – by making the Digispark an Arduino compatible development board all of those remain common. Plug it in, power your project with USB or external sources, program it with the Arduino IDE, and easily use existing Arduino code! But with its small size and low cost you can feel free to leave it in your project, give one to a friend, and use them everywhere!

FT245RL IC testing software. You can set the output and get input status from your PC’s screen. It is thus possible to enable or disable the 8 channels, for a 8-channel input.

This is just a friendly FYI to all hackers. Once you get a little more adventurous you can get real confused about what usb devices are plugged in etc (which com ports,…)
my best new friend is usbdeview from nirsoft http://www.nirsoft.net/utils/usb_devices_view.html
It shows you everything about the plugged in usb devices, updates on the fly, v good

The AVR Stick is a simple data logging device that instantiates itself as an HID keyboard and reports the voltages, along with a ‘timestamp,’ from two pins on an ATtiny85. The device uses open source firmware availabe from Objective Development (http://www.obdev.at/vusb/) called V-USB to implement the USB 1.1 standard. The code that runs the application was based on the EasyLogger example application from Objective development.

I like the handy DCF77 signal. In this project no clock should use it, instead the computers in my home network should be served by a precise time reference. Due to the fact most other interfaces are no longer available on modern computers, it uses the USB to forward the prepared DCF77 signal to the host.

USBTenki is an electronic project to interface sensors to an USB port for collecting weather related data such as temperature. The firmware supports many different sensors and interfaces. It is up to you to decide what your USBTenki will support.

USBTemp provides a thermometer. It is based on the DS18S20 digital thermometers. In addition, the thermometer connects to an USB port – you can read the temperature using a commandline tool. In combination with RRDTool you can easily create temperature graphs
