Meadow’s Status Report for 4/12/2025

Since the last status report I’ve worked extensively trying to get calibration to save on the sensor, but due to the lack of documentation it has been difficult to make work. I’ve found a couple resources of claims to have done so, but even running these examples explicitly doesn’t result in a saved calibration. But I will continue to try methods in the coming week in case I can fix the issue. Aside from that, I’ve discussed the physical build of the hardware portion with Jason and we’ve come to a general consensus on it. We’re currently waiting for a key part for that, but after arrival we should be able to go to TechSpark and assemble holdings for the parts on our barbell clip. Finally I started exploring how to transmit our hardware data to the user in a presentable and easy to understand manner. Although we’re using Jamshed’s app for this, I wanted to be able to test ways to display things like balance before integrating it into the app. We were never going to use a full Arduino for the final build and our new ESP32 models arrived (what we will be using), so I got started on the setup between the new ESP32 and the BNO055 sensor using our existing Arduino script in the IDE. In short, I added the ESP32 as a board in Arduino so we can run our script in the same way, just with the right components. There’s an Arduino IO site that I also began setting up so I can try experimenting with sending the data that comes from my script into visual feedback, similarly to how it should be in our app. I think I’m a bit behind on having the sensor features working well enough to be sent directly to the app, but hopefully I can close some of those gaps in the coming week and a half before the final presentation. So, next week I hope to figure out the best way to display balance to users and make sure that Jamshed is able to read the values output by the BNO into his app in the same way we see them printed from my IDE.
