00:00:06,678 --> 00:00:08,800
[Powered by Google Translate] Christopher BARTHOLOMEW: Hivyo wewe ve pengine nikisikia

2
00:00:08,800 --> 00:00:11,610
mengi kuhusu Arduino, na njia zote kipaji inaweza kuwa

3
00:00:11,610 --> 00:00:15,270
iliyowekwa kwa kutumia C kupokea maoni kutoka kwa vifaa pembeni

4
00:00:15,270 --> 00:00:17,760
kama vifungo, sensorer na knobs.

5
00:00:17,760 --> 00:00:20,970
Au kuonyesha na kudhibiti pato kupitia vipengele kimwili

6
00:00:20,970 --> 00:00:24,130
kama taa, wasemaji, servos na motors.

7
00:00:24,130 --> 00:00:27,510
Lakini ni nini Arduino, kweli?

8
00:00:27,510 --> 00:00:30,640
Arduino ni aina ya microcontroller, na

9
00:00:30,640 --> 00:00:33,920
microcontroller unaweza kufikiriwa kama scaled chini sana

10
00:00:33,920 --> 00:00:36,530
kompyuta ambayo ina vipengele kama vile

11
00:00:36,530 --> 00:00:39,550
processor, kiasi kidogo cha kumbukumbu kwa ajili ya kuhifadhi rahisi

12
00:00:39,550 --> 00:00:42,720
programu, na mbalimbali pini pembejeo / pato kwamba kuzalisha

13
00:00:42,720 --> 00:00:45,090
sasa umeme kama matokeo ya

14
00:00:45,090 --> 00:00:47,330
maelekezo katika programu yako.

15
00:00:47,330 --> 00:00:50,790
pini kwenye Arduino ni hapa interface na

16
00:00:50,790 --> 00:00:54,210
kimwili vipengele kama LEDs, wasemaji, sensorer,

17
00:00:54,210 --> 00:00:56,860
motors, na hivyo zaidi.

18
00:00:56,860 --> 00:01:00,660
Hii ni Arduino Uno R3 ambayo tutaweza kutumia

19
00:01:00,660 --> 00:01:02,210
katika shaka.

20
00:01:02,210 --> 00:01:04,660
Katika video hii, mimi itakuwa kwenda juu ya baadhi tu ya kuu

21
00:01:04,660 --> 00:01:06,110
vipengele wa bodi hii.

22
00:01:06,110 --> 00:01:09,540
Hata hivyo, kama Ningependa habari zaidi, ambayo mimi kupendekeza

23
00:01:09,540 --> 00:01:12,390
kusoma, kutembelea kiungo kwa Arduino wa Uno kamili

24
00:01:12,390 --> 00:01:13,800
vipimo.

25
00:01:13,800 --> 00:01:19,060
Nguvu kwa ajili ya bodi inaweza kuwa alipokea kutoka USB, nje AC

26
00:01:19,060 --> 00:01:24,860
kwa DC nguvu vifaa, au kwa betri viungio.

27
00:01:24,860 --> 00:01:29,620
Kwa mazoezi haya ya video, tutaweza kutumia USB kwa nguvu.

28
00:01:29,620 --> 00:01:32,390
Kama wewe ni nia katika njia nyingine ya kutoa uwezo wa yako

29
00:01:32,390 --> 00:01:35,940
Arduino bodi au unataka kujua zaidi kuhusu pini nguvu,

30
00:01:35,940 --> 00:01:38,830
tafadhali rejea sehemu ya nguvu ya vipimo

31
00:01:38,830 --> 00:01:40,530
kiungo zinazotolewa.

32
00:01:40,530 --> 00:01:44,350
Next, kuna kuu mbili sehemu ya siri juu ya Arduino kwamba sisi

33
00:01:44,350 --> 00:01:48,870
watatumia kutoa voltage kwa sehemu yetu -

34
00:01:48,870 --> 00:01:53,070
digital pini na pini Analog pembejeo.

35
00:01:53,070 --> 00:01:54,840
Kabla ya sisi kwenda yoyote zaidi, hebu

36
00:01:54,840 --> 00:01:57,380
kuelewa sheria hizi mbili.

37
00:01:57,380 --> 00:02:00,450
Analog pembejeo pini ni kwa ajili ya vipengele kama vile knobs,

38
00:02:00,450 --> 00:02:03,150
ambayo kujenga ishara Analog.

39
00:02:03,150 --> 00:02:05,320
Knob inaweza kutoa kiasi tofauti ya upinzani dhidi ya

40
00:02:05,320 --> 00:02:09,000
voltage kati ya pini mbili ambazo ni kushikamana na.

41
00:02:09,000 --> 00:02:11,295
Chukua, kwa mfano, dimmer mwanga.

42
00:02:11,295 --> 00:02:13,960
Kama Knob ni inaendelea katika mwelekeo mmoja, mwanga mapenzi

43
00:02:13,960 --> 00:02:17,340
kuwa mkali kwa sababu lessens upinzani.

44
00:02:17,340 --> 00:02:20,400
Hii hutoa nguvu za umeme sasa

45
00:02:20,400 --> 00:02:23,830
sehemu, ambayo matokeo ya mwanga mkali.

46
00:02:23,830 --> 00:02:27,130
Sasa pini digital ni tofauti kidogo katika

47
00:02:27,130 --> 00:02:29,910
wao kuzalisha signal digital kwamba ni tegemezi kwa

48
00:02:29,910 --> 00:02:32,650
kiasi cha voltage hela pini.

49
00:02:32,650 --> 00:02:35,950
Ishara digital kwa Arduino ni ama juu ya saa 5

50
00:02:35,950 --> 00:02:40,300
Volts, au msingi maana mbali, au Volts sifuri.

51
00:02:40,300 --> 00:02:42,570
Chukua kwa mfano kubadili mwanga.

52
00:02:42,570 --> 00:02:44,320
swichi mwanga ina maadili mbili -

53
00:02:44,320 --> 00:02:45,870
na mbali.

54
00:02:45,870 --> 00:02:48,120
Wakati kurejea mwanga juu ya kutumia kubadili, wewe ni

55
00:02:48,120 --> 00:02:51,270
kutoa nguvu kamili ya mwanga.

56
00:02:51,270 --> 00:02:54,540
Naam, juu ya somo ya digital na Analog, mimi nina uhakika

57
00:02:54,540 --> 00:02:58,940
ve niliona kwa sasa kifupi PWM chini ya digital

58
00:02:58,940 --> 00:03:00,520
siri sehemu.

59
00:03:00,520 --> 00:03:03,750
Hii anasimama kwa Pulse modulering upana.

60
00:03:03,750 --> 00:03:07,260
PWM kuyaharibu voltage zaidi ya muda wa kuzalisha

61
00:03:07,260 --> 00:03:09,730
modulering madhara ambayo ni sawa na wale

62
00:03:09,730 --> 00:03:11,570
pini ya Analog.

63
00:03:11,570 --> 00:03:14,630
Kwa mfano, na kugeuka ya mwanga na mbali kwa haraka kwa

64
00:03:14,630 --> 00:03:17,640
tofauti za urefu wa muda, inaweza kudhibiti wa mwanga

65
00:03:17,640 --> 00:03:18,680
mwangaza.

66
00:03:18,680 --> 00:03:21,380
Basi unaweza kuwa na kuuliza wewe mwenyewe, ikiwa wote una

67
00:03:21,380 --> 00:03:24,470
kufanya ni kutoa baadhi ya voltage kwa sehemu fulani kwa ajili yake kufanya kazi,

68
00:03:24,470 --> 00:03:27,040
nini hata kuwa microcontroller?

69
00:03:27,040 --> 00:03:30,100
Naam, hebu kuchukua kuangalia ngazi ya juu katika microcontroller kwamba

70
00:03:30,100 --> 00:03:32,140
sisi zinaweza kuingiliana na kila siku -

71
00:03:32,140 --> 00:03:33,790
saa ya kengele.

72
00:03:33,790 --> 00:03:36,620
alarm clock ina pembejeo nyingi, kwa mfano vifungo,

73
00:03:36,620 --> 00:03:40,260
ambayo hutumiwa na kuingiliana na programu ya saa ya kengele.

74
00:03:40,260 --> 00:03:43,770
Pia ina matokeo ambayo ni mwanga kutotoa moshi nyaya kuitwa

75
00:03:43,770 --> 00:03:47,620
saba sehemu maonyesho kuonyesha kuwa wakati.

76
00:03:47,620 --> 00:03:50,540
Hii yote ni kudhibitiwa na mpango kwamba ni zilizomo katika

77
00:03:50,540 --> 00:03:52,740
microcontroller wa kumbukumbu.

78
00:03:52,740 --> 00:03:55,570
Sasa, hebu tuangalie mazingira na kuona kama tunaweza

79
00:03:55,570 --> 00:03:58,970
kuiga alarm clock na Arduino hii.

80
00:03:58,970 --> 00:04:01,240
Uko tayari kwenda kulala, lakini itabidi kuweka yako

81
00:04:01,240 --> 00:04:03,010
alarm kuamka.

82
00:04:03,010 --> 00:04:06,100
Tunajua kwamba kwa kutumia kifungo baadhi tunaweza kuweka baadhi

83
00:04:06,100 --> 00:04:08,730
variable, wakati, kwamba anatoa mpango

84
00:04:08,730 --> 00:04:10,040
hali ni lazima kukutana.

85
00:04:10,040 --> 00:04:13,860
Kama vile, wakati hii ni kweli, mpango unapaswa kupeleka

86
00:04:13,860 --> 00:04:17,130
ishara ya mwingine siri kwamba ni kushikamana na msemaji.

87
00:04:17,130 --> 00:04:19,860
Na wakati ishara hii ni kupokea na msemaji, ni

88
00:04:19,860 --> 00:04:22,130
wanapaswa kucheza sauti kubwa.

89
00:04:22,130 --> 00:04:25,300
Hebu kutumia mzunguko rahisi kukupa baadhi ya muktadha na kile

90
00:04:25,300 --> 00:04:26,860
Mimi kuzungumza juu.

91
00:04:26,860 --> 00:04:29,760
Hivyo sasa kwamba alarm yako ni kuweka, hali yako sasa kuhifadhiwa

92
00:04:29,760 --> 00:04:31,170
katika kumbukumbu programu hiyo.

93
00:04:31,170 --> 00:04:34,840
Na baada ya sekunde tu tisa wa usingizi, wewe kusikia kutisha

94
00:04:34,840 --> 00:04:36,836
alarm sounding mbali.

95
00:04:36,836 --> 00:04:38,820
Mimi nina kwenda mbele na kuziba-katika alarm yetu hapa.

96
00:04:47,410 --> 00:04:51,330
Sasa, hatutaki kuamka kabisa bado, hivyo sisi kuhisi kwa

97
00:04:51,330 --> 00:04:52,650
snooze button.

98
00:04:52,650 --> 00:04:56,280
Sisi basi kulala mwanafunzi mguu, au kupinga hii kubwa

99
00:04:56,280 --> 00:04:59,470
alarm sauti kwa kupiga tu kwamba kifungo.

100
00:04:59,470 --> 00:05:02,620
Lakini kweli kile kinachotokea wakati microcontroller mpango

101
00:05:02,620 --> 00:05:05,420
inapokea signal kutoka kifungo snooze?

102
00:05:05,420 --> 00:05:07,630
Naam, wakati button snooze ni taabu, signal ni

103
00:05:07,630 --> 00:05:09,830
kupokea juu ya siri tofauti.

104
00:05:09,830 --> 00:05:12,740
Kwa ujumla, wakati mpango anayempokea pembejeo kutoka

105
00:05:12,740 --> 00:05:16,480
siri humenyuka kwa kupiga baadhi ya kazi kuchelewesha, au kulala,

106
00:05:16,480 --> 00:05:19,600
ishara kwamba alitumwa msemaji siri yetu.

107
00:05:19,600 --> 00:05:23,540
Hii kuchelewa au kulala ni kwa muda mara kwa mara ambayo

108
00:05:23,540 --> 00:05:28,760
kawaida ni dakika tisa, au katika suala Arduino, 540,000

109
00:05:28,760 --> 00:05:30,340
milliseconds.

110
00:05:30,340 --> 00:05:33,380
Kama saa ya kengele si ikizimwa kabla snooze

111
00:05:33,380 --> 00:05:36,540
timer depletes, hali ya mpango wa kutuma mwingine

112
00:05:36,540 --> 00:05:39,560
kuashiria kwa siri ya msemaji, hivyo kugeuka

113
00:05:39,560 --> 00:05:42,350
alarm tena.

114
00:05:42,350 --> 00:05:46,610
Sasa, nini hufanya Arduino maalum kwa cs50 ni yake

115
00:05:46,610 --> 00:05:50,370
maendeleo ya mazingira inatumia lugha C, kutoa

116
00:05:50,370 --> 00:05:53,970
nguvu ya kuomba maarifa yaliyopatikana katika zaidi ya moja kwa moja

117
00:05:53,970 --> 00:05:56,000
mikono juu ya njia.

118
00:05:56,000 --> 00:05:58,750
Ingawa hatukuwa kugusa juu ya pini nyingine maalum

119
00:05:58,750 --> 00:06:01,310
wanaohusika na Arduino, mimi kupendekeza kwamba ziara

120
00:06:01,310 --> 00:06:05,090
vipimo na kusoma juu ya uwezo wao zaidi.

121
00:06:05,090 --> 00:06:07,340
Katika video mwingine, sisi kuchunguza Arduino

122
00:06:07,340 --> 00:06:10,420
maendeleo ya mazingira juu ya appliance cs50 na kuandika wetu

123
00:06:10,420 --> 00:06:13,200
kwanza microcontroller maombi.

124
00:06:13,200 --> 00:06:16,700
Jina langu ni Christopher Bartholomayo, hii ni cs50.
