KMtronic USB Host  Arduino compatible relay board

 

 

 

Multifunctional 8 Relay board with USB Host interface. USB Host allo to connect to board and control relays using any ready USB Device like Bluetooth, Joystick, Keyboard, Remote control, Mouse, RFID Reader, HID devices or custom developed modules.

What is idea?
Build open source universal relay board with possibilities control using any ready or custom made USB device.

After test examples "USB Host Library 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
