LED bars, an Arduino, a little chip and a Moon Bean coffee

by on Feb.07, 2009, under Uncategorized

After a few hours or hacking the old Red Roomba, and failing to fix or workaround the cliff hanger sensor it was time to get some success.

Elmood went out and got me a ULN2803AP chip, which I could use to glue together the Arduino and the tri colour LED bar. I then used some of the arduino examples to pulse and colour and mess around a bit.

The next step, perhaps using I2C to control individual bars (I have 10) and line them up on the stairway!
