Week 3 Update

The group was faced with a rather challenging issue: how to connect the two servos together. The purpose of those two motors is to allow up-down and left-right movement (see Figure 1). One of the motors (pointing upwards) rests on the holder of the stand, which will provide the left-right movement. The other motor is placed on top of it, but is laying on its side with the motor pointing to the side. This will provide the up-down movement. Having the motors tightly connected is crucial because it contributes to how accurate the keys are being played. A wooden connector was made (see Figure 2), but it was too bulky and restricted motion. We decided to buy smaller motors (link below), so that we can hot glue them. The motors we have now are rented from the school, so we cannot do anything permanent to them. Once the motors were delivered, the group tried to two motors with rubber bands first. The rubber bands work so well that the idea of gluing them together was ditched. Now, with the smaller motors, the coding to hit each key was started, and was finished by the end of the week. A sample code will be found below. Simultaneously, rough sketches were made of the overall appearance of the project and it's pseudocode. Both of them will also be provided below.
