Mary and Bertha (2010) point out that âCommunication is the transmission of information and meaning from one individual or group to another.â (Page 5) The term communication means that the sender has an idea and the sender encodes the message which will be decodes by the receiver.
Playback Controls. Playback controls came into existence due to the popularity of cell phones. Originally, the controls were located on the headset cable and included a small microphone and buttons to control the call, such as the ability to hang up.
Servo control. Servo control is achieved by sending a servo a PWM (pulse-width modulation) signal, a series of repeating pulses of variable width where either the width of the pulse (most common modern hobby servos) or the duty cycle of a pulse train (less common today) determines the position to be achieved by the servo.
