Control ScreenThe manual control system is mainly designed for debugging purposes. The benefit of thissystem comes with event processing. In figure 5, the event list is shown. This allows the systemto respond to events triggered by inputs connected to the GPIM(s).The list contains a name and description of each event to aid the user as the event list willprobably have many events for an average size home. Adding and editing an event is verysimple using the built-in event editor. The system also has safeguards to prevent edit entrymistakes.The security tab, shown in figure 6, displays configuration parameters for the security system.Modeled after standard security systems, the security interface features multiple user codes withlogging

Students learned to do the conversion by canceling units as in the example shownin Figure 3. We put a speed of 30 for 10 seconds to move forward. Speed of 30 in Scratch is 0.3 m/s.Figure 3. Example of How students learned Conversion for Speed.The procedure start Camp 12 Extensions and the student’s first assignment with the Drone is given inAppendix A.The first Scratch program using the drone and a condition statement had as a goal is to have the dronemove up and down based on the output of altitude sensors.

Linearity is ameasure of how well the transducer output increase linearly with increasing pressure.Linearity eliminates the need for a complicated set of algorithms to calculate the dynamicpressure from the pressure recorded by the sensor.Pressure range In order to pick the right sensor, it was first necessary to calculate the range ofpressures the sensor will be deployed in. The initial bench test was done in a still watertank with a depth of 3 feet. The calculation of the pressure range was as follows:  kg  mP = ρgh = 1000  9.81 2 (0.9144m ) = 8.96 x103 Pa = 1.30 psi  m  s  At 3 feet (0.9144m) of water, the pressure

. The physical properties of the accelerometer included sensitivity of102 mv/(m/s^2), a frequency range of 0 to 100 Hz, and a 10 Hz phase response of under 3°1.The accelerometer contains a voltage regulator integrated within its structure. This allows forexternal power to be supplied by any source within the 10 to 30 VDC excitation range. Thechange is capacitance is detected by a capacitance bridge where each arm of the bridge functionsas a capacitance divider. The outputs of the bridge are then amplitude modulated signals that aredirectly proportional to the changes in capacitance. A series of diodes and capacitors within theaccelerometer are used to demodulate the signals which are then summed, amplified, and filteredto provide a voltage
