2. in the scout course, for send of secret
information usually using codes are secret like as
semaphore code and morse code, where it’s just know
by the group having in interest.
at the scout usually semaphore code doing by
human as information of sender, but with applied of
technology, sending code of information able to change
by semaphore robot as model for learning of students.
3. Making model of instrument semaphore code
in the form of semaphore robot for learning
the scout students.
4. - Distance maximal given input are 100 cm from the mic.
- Design just implementation code from A-Z.
- Making mechanic consist at the arm robot for simulation model semaphore
code.
- Using 4 servo as movement arm for make semaphore code.

11. System able to discriminate the voice whistle

identification one by one voice value that saved
And can to showing to output shaped movement
semaphore robot.
Voltage output microphone depend on amplifier
that voice and have value between 0-50mV.
For Getting the best amplifier, microphone
output must be use pre-amp first before use op-amp.
Because output microphone was to small
and can damaged voice signal.
total tolerantion error average subsystem up to
8%.
Success level this robot up to 98%.
