Groupmates¶

What We Made?¶

For machine week, our group went through many ideas but the one that we landed on was a whack-a-mole machine. We decided to add a twist to it and use Neil Gershenfeld’s head as the moles. Originally we were going todo our teachers heads but we decided it would be easier todo all the same head because then we coudl use it for our mold and casting week as well.

What I did¶

Combining Servos and Touch Sensors – Elle¶

Combinging the servos and touch sensors were hard at first because we weren’t sure how to wire it and make the code work. To fix this we plugged each servo into a new digital pin on the seeed. Then once we did that I looked at the code and studied it for a long time. Then after that I realized that the code was very simple and I just needed to make 5 different variables for all the different servos and touch sensors. Then once I did that, the code was as simple as if the touch sendor 1 is clicked the head 1 goes down. Below is a video of first getting 2 to work at once.
