My 4th period class made a fun little program for their robots after the Wave. First they got the robots to spin in place, one after the other, then in return order. While watching their robots perform the students started humming noises from a lower pitch to a higher one. I told them they could get their robots to make those noises and the students’ eyes lit up. Here’s the result:
The cool thing about this program is it introduced the students to the idea of parallel programming which is a lot easier to do with EV3.
