• Lab Meetings (4 hrs):
  • met with the Professor and TA to discuss the design review presentation
• Indiviudual Work (8 hrs):
  • wrote the testing, validation section, architecture of operations, and bill of materials
  • Wrote initial Arduino script and constructed basic circuit with PWM

Progress:

Behind Schedule – This week I implemented the Arduino script to send PWM inputs to the H-Bridge. The script periodically would switch the direction of the current. We set up a circuit with a miniature propeller as the motor connected to the H-Bridge. With the periodic propeller switch in the script the direction the propeller spins would switch. We are behind schedule in that we still need to design a new CAD track and carrier that addresses our stability issues. Next week, I plan to figure out and research how the ultrasonic and Hall Effect output information and how to read it properly.

Next Week Deliverables:

1. redesign track and carrier with connection grooves for increased stability
2. Write the initial script for the hall effect and ultrasonic sensors. The main goal is to figure out how the output of the sensor and how to interface with them with the Arduino.
