[pic]When you press the numbers on your phone to make a call‚ the tones you hear are called Dual Tone Multi Frequency tones (DTMF)‚ and they represent one of 16 possible numbers on the keypad. The DTMF tones are made up of frequency pairs ranging from 697 Hertz to 1633 Hertz. There are actually eight frequencies that form a 4x4 matrix of 16 possible tones by mixing the pairs together. DTMF signaling has proven to be a very robust method of sending data over the telephone system‚ and it has become

over an interval or period of time‚ where the period is the inverse of the frequency of the waveform. Similarly‚ the PWM changes the pulse width‚ resulting to changes in the duty cycle and therefore averaging the output power signal [31]. Six of Arduino 14 I/O pins can be implemented for PWM purpose (8 bits decimal integer with 0-255 range) using analogWrite whereas all the pins can be performed with digitalWrite method [24]. For this research‚ pin 10 will be used with the aid of analogWrite method

1+R2/R1 for a non-inverting amplifier‚ R2 = 14.4 R1. Maximum precision in the R2/R1 resistance ratio is achieved using a potentiometer instead so it can be adjusted exactly to the desired output. This signal will be read from Arduino with a full scale of 5V and then‚ Arduino decides which output pin activate to supply the voltage divider chain. Since the voltage to be read can be higher than 5V‚ the measure is taken divided by two taking advantage of the voltage divider of the following differential

The team also noticed some inconsistencies in the graph that they feel could be fixed by changing their code. One of these issues being that cutting off power completely from the AEV’s resulted in the motors having to do extra work in order to get started again. Possibly changing the code so the amount of power supplied to the motors gradually decreased over time instead of stopping the power completely‚ could make for a more efficient AEV. Theoretically speaking‚ when a plane begins to near its
