Mouse Droid not only celebrated Halloween, but also her 6 month date of being relatively complete.
I learned the basics of servos with Arduino to give her a spooky spider costume.
I tried to make multiple servos work, but have an issue with either not enough or too much power. Looks like another fun challenge for the future. Another disappointment was discovering I had neglected the battery for too long, and it is dead. A new one is on the way, but obviously not in time for Halloween night.
Either way, Mouse Droid was able to dress up and get some candy.
