This week, we began to work in earnest again on our prototype. Thom is working on building a calibration system into the Arduino program. He is working on adding a button to the Arduino that will trigger a calibration process when pressed. Initially, this button seemed to interfere with the output of the IMU. We will investigate the circuits built to try to resolve this issue, so that we will be able to use this button without triggering IMU problems. Thom will also be working to write the code that will allow the IMU to be calibrated for its position on a user’s head.
Emma drew up a plan for the rest of the semester, outlining what tasks have to be completed in what order. She also began working on the headband itself. She obtained fabrics from Joann’s, including felt, swimsuit liner, and elastic, and is working to construct a safe, comfortable headband that will securely hold the IMU in place. She will continue construction of the headband into next week. Katelyn is working with the Raspberry Pi and the haptic motor. She wrote a short Python program that causes the haptic motor to vibrate (with the haptic motor connected to a GPIO pin and to ground). This required Emma to solder the haptic motor to two longer wires that connect well to a breadboard. For next week, she is researching the syntax to use in Python in order to get data from the Arduino that could determine the output from the haptic motor. She will also learn how to write code in Python that will start and stop audio output. Comments are closed.
