Subsystem Testing

Subsystem: Electrical

Pressure Sensor

The goal was to test components if they were in working conditions.

Using an Arduino UNO, resistance of 1 M-ohms, wires, SEN-08685 ROHS Flexiforce Pressure Sensor and the code that has been listed below. Each Arduino and each Pressure sensor was tested and the result of the testing is that Arduino Uno's and pressure sensors that were ordered are in working condition.

// int flexiForcePin = A0; //analog pin 0

void setup(){ Serial.begin(9600); }

void loop(){ int flexiForceReading = analogRead(flexiForcePin);

Serial.println(flexiForceReading); delay(250); //just here to slow down the output for easier reading }

Lab View Code

The control system was controlled with manual inputs of position for the dome within 2 degrees of the desired position. Parking of the dome was successfully tested as well as shut down of the system.

During preliminary testing, relays begin to seize up if the desired position was exactly zero degrees but had no issues moving through the zero point. Resetting of the relays required a simple removal and reinsertion of the relay but an observing run will be required to ensure this will not be an issue for the final iteration.
