Morse Code tau tsim los ntawm Samuel Morse xyoo 1836, yog tus neeg Asmeskas tsim thiab pleev xim. Cov xov tooj sib tham uas Samuel Morse tsim tau tso cai rau tib neeg xa xov hluav taws xob hla cov xov hlau. Lub sijhawm no, tsis muaj xov tooj cua lossis xov tooj yog li txoj hauv kev ntawm kev sib txuas lus tau txais sai sai thoob plaws Tebchaws Meskas. Nov yog qhov hloov pauv hauv keeb kwm ntawm kev sib txuas lus.

Cov teeb liab hluav taws xob uas xa thiab tau txais tuaj yeem sib txawv los ntawm cov cim luv thiab ntev. Cov cim luv raug xa mus rau "dits", qhov twg ntev cov cim qhia tau hu ua "dahs". Dits yog sawv cev nrog cov dots thiab dahs yog sawv cev nrog cov dashes.

Morse code yog ua raws lub sijhawm sib nrug ntawm cov ntawv, dahs, ntawv thiab lus. Nov yog qhov koj tuaj yeem qhia lawv sib nrug thaum txiav txim siab:

- Tus lej yog 1 chav nyob ntawm lub sijhawm

-A dah yog 3 chav nyob ntawm lub sijhawm

-Qhov ncua ntawm cov ntawv yog 3 units ntawm lub sijhawm

-Ib ncua ntawm cov lus yog 7 chav nyob ntawm lub sijhawm

-1 chav nyob ntawm lub sijhawm ntawm dits thiab dahs

Qhov nrawm uas Morse Code tau xa mus yog feem ntau hu ua WPM, lossis lus ib feeb. Tom qab ua qee qhov kev tshawb fawb, peb pom tias lo lus "Paris" tau siv ua tus qauv rau qhov ntev ntawm ib lo lus. Qhov laj thawj yog vim tias "Paris" xav tau sijhawm 50 chav nyob kom xa mus. Piv txwv li, yog tias koj yuav xa lo lus "Paris" 10 zaug, koj tab tom kis ntawm 10 WPM.

Kauj Ruam 1: Yam Koj Yuav Tsum Tau Pib

Nov yog cov khoom koj yuav xav tau kom rov ua dua peb cov kev sim:

- Ib Arduino

- Ib daim ntawv qhia zaub mov

- Tus Hais Lus

- LED (peb xaiv xiav)

-220 ohm resistor

Cov kauj ruam tom ntej ntawm Cov Lus Qhia no yuav qhia koj yuav tsim peb li Arduino Morse Code System li cas.

Kauj ruam 2: Tsim

Txuas tus tiv thaiv rau GND thiab rau cathode ntawm LED.

Txuas lub anode rau Arduino tus pin 12.

Arduino tus pin 9 rau tus hais lus zoo.

Hais lus tsis zoo rau GND

Arduino tus pin 7 rau khawm.

Khawm rau hauv av.

Kauj Ruam 3: Daim duab Circuit Court

Kauj ruam 4: Daim ntawv thov

Rau peb txoj haujlwm hauv chav kawm, peb yuav tsum tsim phiaj xwm rau cov tub ntxhais kawm uas yuav ua tiav Cov Qauv Txuj Ci Txuj Ci, hauv qhov no peb muaj tus qauv 17 (E, F, thiab G):

Tus Qauv 17-E: Cov ntaub ntawv tuaj yeem tau txais thiab xa los ntawm ntau yam khoom siv thev naus laus zis, suav nrog cov ntawv luam tawm thiab hluav taws xob.

Benchmark 17-F:

Kev sib txuas lus thev naus laus zis yog kev xa xov ntawm cov tib neeg thiab/lossis cov tshuab hla kev deb los ntawm kev siv thev naus laus zis.

Benchmark 17-G:

Cov ntawv, cim, cim, thiab cov cim yog cov cim uas sawv cev rau cov tswv yim, qhov ntau, cov ntsiab lus, thiab kev ua haujlwm.

Morse Code tso cai rau ib tus neeg xa thiab tau txais cov lus siv cov lej yooj yim kawm-muaj peev xwm. Txoj haujlwm no tso cai rau cov tub ntxhais kawm ua lub tswv yim nyuaj, thiab hloov nws mus rau hauv cov txheej txheem ua haujlwm yooj yim. Peb ntseeg tias txoj haujlwm no yuav koom nrog hauv chav kawm vim tias tib neeg feem coob tau hnov txog Morse Code tab sis tsis nkag siab tias nws ua haujlwm li cas thiab ua haujlwm li cas.

Kev qhia qhov no rau cov tub ntxhais kawm muab lawv cov txuj ci tshwj xeeb rau lawv uas lawv tuaj yeem khaws mus tas ib sim neej. Leej twg paub, tej zaum lawv qhov kev paub ntawm Morse Code yuav los ua ke nyob rau ib hnub.
