WORK ACCOMPLISHED:
This week I continued working on the wristband subsystem.
I wrote code to the sensor script so it can send a signal to the HC-05 when an object is detected within a certain range, but I haven’t been able to test it due to a road block with configuring the HC-05 bluetooth modules. I’m struggling to establish connection between to the two HC-05 modules because I have been unable to get a response from them individually using AT Commands on the Micro Arduino. The AT Commands are needed to sync the modules and dictate which one is the “master”. I’ve tried various solutions I’ve seen online but will now pivot to trying to configure the HC-05 with the RPi4 instead because this seems to be a common issue with the micro Arduino.
PROGRESS:
I’m pretty behind on tasks right now, but if I’m able to establish how to send data I will make a significant leap. I wanted to have a functioning blindspot detection system for the interim demo by now. I will continue to work on establishing connection between HC-05s throughout the weekend. I also noticed theres a really good radar sensor in the ECE inventory so I will put in a request for that.
NEXT WEEK’S DELIVERABLES:
Next week, I aim to have basic functionality of the blindspot detection subsystem and make any tweaks based on feedback from the interim demo. Also, I will get a new radar sensor from ECE inventory.
