What did you personally accomplish this week on the project? Give files or photos that demonstrate your progress. Prove to the reader that you put sufficient effort into the project over the course of the week (12+ hours).
I personally accomplished creating a function that can take in a 2D array of motor pins, 2D array of motor powers, array of timings, and array of pauses. This function can then drive the motors in the given pattern set by the inputs. This is all in the team GitHub under mutlipl_wave.io. It’s print statements are not cleaned up because I’m still probably going to use those with testing further on. I also started to make a Response class which will hold all the motor info so you can just tell the class to “run_response” and have the response you want happen. I started setting up the .cpp and .h files in “BasicDesign” but it’s not functional yet. Lastly, I did some math for what I would need for a PCB to take in 3-wire PWM and make it 2-wire PWM, but I forgot to take a picture of it and don’t have it on hand. Lastly, I also worked on the project report this week.
Is your progress on schedule or behind? If you are behind, what actions will be taken to catch up to the project schedule?
I am on schedule for what I had planned. However, I had assumed the motors would run properly so that’s a parallel task I’m working on in addition to what I have on the schedule for myself.
I have decided to exchange the Adafruit PWM servo driver for a Sparkfun I/O expander. The expander can do digital, analog, and PWM writes. The one thing I’m unsure of is if it can supply 5V. The device is rated for working up to 5.5V but it has 3.6V operating power. Anyways, it only costs $7, $15 with shipping. I figure I can pick it up when I get back from vacation on Friday, try it out, and then see if I need to come up with the PCB that I talked about last week. And I’ll still be on schedule because I didn’t plan anything for this week.
What deliverables do you hope to complete in the next week?
Absolutely nothing. This is the last thing I am doing before I’m fully on vacation. Once I’m done, I’m checked out. Anything productive will happen when I’m on a beach, soaking up sun and possibly thinking about what I may want to do when I get back.
But the week after, I plan to test the Sparkfun I/O expander. If it worked better than the Adafruit device, I will edit my current code to include it. I also plan to continue to turn the functions to run the motors into a class.
