We develop relay boards and have full range of interfaces: RS232, USB, RS485, LAN…
I wanted to share our new project: Relay board with USB Host interface. We using ATmega 2560 and Chip MAX3421E so is Arduino ADK compatible.
What is idea? Build open source universal relay board with possibilities control relays using any ready or custom made USB device.
After test examples "USB Host Library 2.0 for Arduino" Lauszus (TKJElectronics) and Oleg Mazurov we just successfully control relays using: USB Keyboard USB Mouse USB Joystick USB Bluetooth USB Remote control USB RFID Reader
Now try to expand examples with many more USB devices like: USB WIFI module USB 3G Module Android USB Control USB DS1820 Temperature reader Custom USB Modules
Later today will publish the first example: control relays using USB Keyboard.
We are not professionals in the Arduino programming and prepare only simple but working examples. Currently sketch use around 5-7% of memory ATmega so there are many possibilities to customize the certain projects.
If you want to collaborate, give suggestions, or say anything related to the project, please reply to this post or email me.
Hope you like the board.
