Accomplishment: This week I populated the PCB with all components except for the N-MOS transistors which haven’t arrived yet. I also flashed the Jetson’s microSD card with the developer kit SD card image and began setting up the Jetson.
Progress: I had planned to finish populating the PCB this week, but was set back since the transistors were not available in the campus lab rooms and I had to place an order for them. This put me behind schedule, but since the transistor is only used for interfacing the vibration motor with the Jetson, I am still able to test the buttons and ultrasonic sensor using the PCB.
Projected Deliverables: This week I plan to test the buttons and ultrasonic sensor using the PCB, and will solder the transistors and test the vibration motor once the transistors are delivered. To test the PCB, now that the Jetson has been set up, I will also write the GPIO setup code using the RPi.GPIO Python library. Lastly, I will place an order for the USB audio converter so that we can integrate audio output with the Jetson.
