I want to make a Halloween batman dog costume that has a flapping cape. I am going to use a continuous micro servo to pull the cape up and down, and use an accelerator to detect whether or not the dog is standing up or laying down, so that when the dog is standing up, the cape will flap, but when the dog is turned to the side, the cape will not move. I also plan on adding RGB LEDS around the batman symbol. I the costume to look like the cape is flapping in the wind when the dog is running or just standing up.
