|
| Bluetooth:
technology that makes possible to transmit signals over short distances between telephones, computers and other devices, like household appliances, without the use of wires. |
|
| Controller:
it is a control circuit for a servo. In the simples case it is a remote control unit that has one or more joysticks, knobs or levers. Direct digital control (i.e. not remote control) of a servo is relatively simple if a stable, accurate timebase is available. A microprocessor or microcontroller with a quartz crystal driven clock will do fine. |

| Sensor:
a device that responds to a stimulus, such as heat, light, or pressure, and generates a signal that can be measured or interpreted. |
| Servo (servo motor):
is any kind of electric motor whose speed or position is controlled by a closed loop feedback circuit. An example is the drive motor in a floppy disk drive, which must maintain an exact rotational speed. The speed of the motor is measured by a tachometer that is physically coupled to the output shaft of the motor. The tachometer produces a voltage that is proportional to the speed. This voltage is compared to a reference point and the difference, or error, is used to adjust the speed of the motor, either up or down. |
