Christmas Scribbler

Level: Intermediate
Skills Required: Soldering
Hours to Complete: 2

Since the S2 Robot is already red, it really lends itself well to holiday projects. This project uses the S2 Robot to play ‘O Tannenbaum’ to objects it sees. Using the S2 Robot’s hacker port, lights on a hacked Christmas tree blink in time with the song.

Small Christmas trees like the one used in this project can be found at almost any craft store (this one was actually nabbed from Home Depot). Most come with a continuous strand of LEDs wound around the tree, so the strand will need to be cut at several points in order to create an alternating blinking effect. Since the cut wires aren’t easily connected to the S2’s hacker port, pluggable female wires will need to be soldered to the LED wires.

Programming the S2 Robot will be accomplished using a combination of the S2 GUI and the Propeller Tool. The S2 GUI will be used to program the music and navigation code, but the software doesn’t allow direct access to the Propeller I/O connected to the S2 Hacker Port. That’s when the Propeller Tool to will be used to add code to control the Christmas tree’s LEDs.
