Just by adding a few wires you can use the BlinkM as a small Arduino. So next time you need a simple microcontroller that can be stuffed anywhere you might want to use a BlinkM.
“The BlinkM board doesn’t have nearly the I/O pins and other features of a real Arduino board. But it is very tiny. Here are its capabilities:
– 0.4″ square (MinM), or 0.6″ square (BlinkM)
– 8MHz clock speed
– 8k bytes Flash ROM (4kB on ATtiny45)
– 512 bytes RAM (256 bytes on ATtiny45)
– 512 bytes EEPROM (256 bytes on ATtiny45)
– 5 I/O lines total, partitioned as:
– 3 high-brightness LEDs in RGB package
– 2 digital I/O lines
– 1 analog I/O line (shared with digital)”
