Week 6

The accomplishments made this week were few in number, but integral to the project's success. The Servo Motor can now be activated by the PIR sensor, but does not rotate in one direction for an extended period of time. In addition, it seems that the PIR sensor struggles to detect a significant change in the IR when it is used in a bright room, such as the Innovation Studio. When it is used in a darker room, there is less IR, making it easier for the sensor to detect the change in radiation caused by a person walking in front of it. Once these two devices are able to successfully work together, they will be able to cause Jack's head to exit the box. The Servo Motor will be attached to the screw of the scissor jack, so that when the PIR sensor detects a person in front of it, the Servo Motor will know to begin rotating. This rotation will cause the platform on which the head rests to be elevated.

The circuit used to connect the Arduino board

While on the topic of the head, it should be noted that three of the eight parts required to assemble the head have been printed using the H400 3D printer. The goal is to have all eight parts printed and adhered to each other by the end of the Week 8 Lab session.

When the part on the left is adhered to the part in the middle, a hole will exist between the parts, which will be where the spoke of the part on the right will be inserted. The part with the spoke is one side of Jack's jaw.
