Greenmunch will be at a trade show this weekend and I wanted to make an small, autonomous, arduino robot to show off some paper straws, so this is what I came up with, It consists of 1 Lego plate, 2 standard servos, 1 continuous servo, some paper straws, a bunch of wires and an arduino Uno. as you can see in the video, the potentiometer on the left controls the speed and direction of the continuous servo, and the potentiometer on the right controls the delay in between movements, or the overall movement speed of the standard servos.
here is my code:
