Dandelion Bluetooth IO interface

by on May.25, 2011, under My gadgets

Dandelion is a project inspired by Gainer. It proves a simple solution to interact between the physical world and the digital world. When connecting the board to a computer, it acts as a serial port on the computer. That makes it easy to be manipulated by any program language. Then various sensors or actuators can be connected to its 10 digital IO ports and 2 analog input ports. All commands and data are sent in ASCII forms and those commands are user-friendly. Most important, it connects via Bluetooth. This can save a USB port and communicate in distance.
