Once it was determined which subsystems were being focused on for this prototype, all the parts were ordered and assembled together. The team had to wire the circuitry together for the sensors as well as attach tubing from the pump to the sensor. Through a few iterations, the team arrived at their second iteration alpha prototype pictured below. As described above, the four main subsystems in this prototype were the pump, pressure sensor, cup, and data acquisition. This prototype was controlled through the Arduino and needed software to be developed in order to record sensor values which is discussed in the software debugging section below. The team was extremely happy with the outcome of the assembled second iteration prototype.
