This week I have been focusing on the hardware components as well as building the device. Last Sunday, the RPi5 required reflashing due to a corrupted SD card, which MM and I worked to set up again, after which I worked on setting up the Bluetooth to Rpi to servo connection via I2C. I used client/server code, which we have been using as a basis for our Bluetooth connection and I was able to send a signal to move the servos. Then we soldered the PWM driver and connected the 6 servos to test if all of them worked. In order to do this, I added more code to get all 6 servos moving using an I2C module that allows the client to pick which servo to move. When we tested with 1 servo, it moved 180 degrees, but when we tested with all 6, they only moved about 90 so I have been spending some time troubleshooting that. When MM sshed into the RPi from her device, the servos did not move at all, but when I tried from my device they did, so we need to figure out what kind of issues can come from that. With all of the 3D printing components printed and the hardware connection established, I have started to build our device and its housing. The backing that I designed initially is too large to be 3D printed, so I am using other materials to fit the exact specifications of our design.  I will also continue working with MM over the course of next week on using the WebSocket to move our servos via the deployed application and once we get that working we will test the dispensing functionality in our device.
