This week I attended the ethics lecture and confirmed backup parts orders. Last week I was concerned about how the voltage divider on the flex sensors would interact with the input impedance to the ADC, so I tested a TL072 op amp as buffer. It turned out this wasn’t necessary after I worked with Katherine to get the flex sensor calibration working on the build in Pico ADC pins. We also connected IMU to Pico with I2C and were able to read out data. Confirmed that the connections worked for battery power and microusb power. My part in this was measuring voltage, connecting the test setup, and referencing suggested designs in spec sheets. Tomorrow (Sunday 3/22) we’re going to assemble the glove and try to get preliminary data readings.
