The output should show the value of the weight being put on the pressure sensors and display the axes of the board using the MPU6050. The output will ideally look something like the attached where the blue rectangles are showing the angle of the board as it is moved, and the pressure sensors are each displaying their independent values. If this output can be done via the bluetooth connection to a phone, that would be great. If not, an output to the Arduino IDE is fine too.
