00:00:00,270 --> 00:00:05,460
Hello and good morning

2
00:00:06,510 --> 00:00:07,890
today I am going to show you

3
00:00:07,890 --> 00:00:11,130
how a real arduino board works. Until

4
00:00:11,130 --> 00:00:13,770
now you've just been programming using a

5
00:00:13,770 --> 00:00:14,670
simulation

6
00:00:16,800 --> 00:00:18,840
but you can see I now have

7
00:00:18,840 --> 00:00:20,970
a real arduino board on the right

8
00:00:20,970 --> 00:00:22,230
side of your screen

9
00:00:24,690 --> 00:00:26,160
it looks similar to the one in

10
00:00:26,160 --> 00:00:27,060
the simulation

11
00:00:29,790 --> 00:00:31,740
here in the upper part we have

12
00:00:31,740 --> 00:00:33,750
the digital connections the same way you've

13
00:00:33,750 --> 00:00:36,930
been using and here we have a

14
00:00:36,930 --> 00:00:39,840
protoboard with three LED already connected

15
00:00:40,230 --> 00:00:41,640
yellow green and red

16
00:00:43,230 --> 00:00:45,090
each one is connected to its own

17
00:00:45,090 --> 00:00:46,950
wire and down here

18
00:00:48,300 --> 00:00:49,890
I have the ground connector

19
00:00:56,340 --> 00:00:58,680
and they are all connected to the

20
00:00:58,680 --> 00:00:59,490
arduino board

21
00:01:02,460 --> 00:01:05,220
so I can connect these three to

22
00:01:05,220 --> 00:01:10,350
connector numbers thirteen twelve and eleven and

23
00:01:10,350 --> 00:01:12,000
then the ground will close the circuit

24
00:01:12,780 --> 00:01:15,120
and the three other connectors will give

25
00:01:15,120 --> 00:01:17,400
or not energy to the protoboard

26
00:01:18,930 --> 00:01:20,610
so now we have everything we need

27
00:01:20,610 --> 00:01:21,630
for the real one

28
00:01:25,470 --> 00:01:27,690
now for the simulation we can connect

29
00:01:27,720 --> 00:01:30,450
everything the same way and I'm going

30
00:01:30,450 --> 00:01:31,410
to do it like this

31
00:01:34,590 --> 00:01:36,270
now I'm going to connect the three

32
00:01:36,270 --> 00:01:38,940
LED these from the library

33
00:01:42,030 --> 00:01:43,230
so click and drag

34
00:01:51,390 --> 00:01:53,190
and we can change the colors to

35
00:01:53,190 --> 00:01:53,700
yellow

36
00:01:56,820 --> 00:01:57,660
and green

37
00:01:59,280 --> 00:02:01,560
and then read and now we need

38
00:02:01,560 --> 00:02:04,440
the three resistors as well all with

39
00:02:04,440 --> 00:02:06,090
two hundred and twenty ohms

40
00:02:09,539 --> 00:02:11,460
and remember that these just get connected

41
00:02:11,460 --> 00:02:13,680
to the cathode or the straight side

42
00:02:13,680 --> 00:02:14,370
of the LED

43
00:02:26,280 --> 00:02:28,410
so now I'm going to connect the

44
00:02:28,410 --> 00:02:31,500
LED the first two thirteen is

45
00:02:31,500 --> 00:02:32,580
going to be the red one

46
00:02:35,460 --> 00:02:37,620
and the next will be the green

47
00:02:37,620 --> 00:02:38,760
one to twelve

48
00:02:39,870 --> 00:02:41,370
and then this one will be yellow

49
00:02:42,960 --> 00:02:44,280
it doesn't matter if they cross each

50
00:02:44,280 --> 00:02:46,380
other they're still connected with each one

51
00:02:46,380 --> 00:02:47,910
crossing above the previous one

52
00:02:49,500 --> 00:02:52,500
and also we will add the ground

53
00:02:52,530 --> 00:02:55,650
to this horizontal line black as always

54
00:03:00,690 --> 00:03:01,590
and then one here

55
00:03:06,330 --> 00:03:07,890
how about if i connect it in

56
00:03:07,890 --> 00:03:09,990
a different way just to see it

57
00:03:10,080 --> 00:03:13,740
more clearly so yellow is actually going

58
00:03:13,740 --> 00:03:14,550
to move here

59
00:03:16,380 --> 00:03:18,930
and then read here so the colors

60
00:03:18,930 --> 00:03:21,810
will change to correspond as well just

61
00:03:21,810 --> 00:03:22,740
so you can see it better

62
00:03:28,680 --> 00:03:30,690
okay now we have all three resistors

63
00:03:30,690 --> 00:03:33,930
connected to ground and the LED are

64
00:03:33,930 --> 00:03:35,100
connected to the wires

65
00:03:43,380 --> 00:03:45,330
now I have the same exact circuit

66
00:03:45,330 --> 00:03:47,340
on the real bored with the same

67
00:03:47,340 --> 00:03:49,920
connections so now we are going to

68
00:03:49,920 --> 00:03:53,760
program the simulation first and we're going

69
00:03:53,760 --> 00:03:55,050
to do it the same way that

70
00:03:55,050 --> 00:03:57,180
we programmed the LED sequence

71
00:03:59,580 --> 00:04:00,750
so we go up to the code

72
00:04:01,440 --> 00:04:05,040
and first we need a thirteen to

73
00:04:05,040 --> 00:04:08,220
be defined as high or on

74
00:04:14,280 --> 00:04:15,750
and then it will wait or continue

75
00:04:15,750 --> 00:04:17,070
shining for one second

76
00:04:20,160 --> 00:04:22,079
and then off or low

77
00:04:25,560 --> 00:04:27,598
and we will duplicate and repeat this

78
00:04:27,598 --> 00:04:31,020
same sequence with twelve and eleven

79
00:04:32,340 --> 00:04:33,930
so just remember you can right click

80
00:04:33,930 --> 00:04:36,240
to duplicate and then change the numbers

81
00:04:45,840 --> 00:04:47,130
eleven and

82
00:04:48,240 --> 00:04:48,660
eleven

83
00:04:49,830 --> 00:04:52,590
ok everything has been programmed properly

84
00:04:53,760 --> 00:04:55,740
we can close this a code box

85
00:04:55,740 --> 00:04:58,020
just to see it better and check

86
00:04:58,020 --> 00:05:00,450
the simulation and it works perfectly

87
00:05:01,860 --> 00:05:04,650
now the idea of simulations is that

88
00:05:05,340 --> 00:05:07,230
they're really useful to check if everything

89
00:05:07,230 --> 00:05:10,260
has been designed properly because sometimes we

90
00:05:10,260 --> 00:05:13,050
make mistakes when we're designing and doing

91
00:05:13,050 --> 00:05:15,690
the simulation before making the real circuit

92
00:05:15,960 --> 00:05:17,340
is always a good idea

93
00:05:18,990 --> 00:05:20,940
now that we know that the simulation

94
00:05:20,970 --> 00:05:23,850
will work how can we program the

95
00:05:23,850 --> 00:05:25,890
real circuit the one we have here

96
00:05:26,100 --> 00:05:28,380
if we want to program it directly

97
00:05:31,860 --> 00:05:34,230
will you need the code which we

98
00:05:34,230 --> 00:05:35,700
know is over here so if you

99
00:05:35,700 --> 00:05:36,870
pull it back up

100
00:05:37,980 --> 00:05:39,810
we don't want the blocks though we

101
00:05:39,810 --> 00:05:41,730
need something else so if you go

102
00:05:41,730 --> 00:05:44,430
to this drop down and we want

103
00:05:44,430 --> 00:05:46,920
to see the text so this text

104
00:05:46,920 --> 00:05:49,470
is the actual code for the program

105
00:05:49,500 --> 00:05:50,520
and this is what we are going

106
00:05:50,520 --> 00:05:52,500
to upload to the real arduino board

107
00:05:52,770 --> 00:05:55,470
so you right click and copy and

108
00:05:55,470 --> 00:05:57,150
we're going to open a new program

109
00:05:57,150 --> 00:05:58,080
called arduino

110
00:05:58,080 --> 00:06:00,420
IDE this is the

111
00:06:00,420 --> 00:06:02,310
software that we use to program the

112
00:06:02,310 --> 00:06:02,970
real board

113
00:06:04,937 --> 00:06:07,050
now I'm going to just delete the

114
00:06:07,050 --> 00:06:09,570
code that appears by default and I

115
00:06:09,570 --> 00:06:11,790
will paste the code that we generated

116
00:06:11,790 --> 00:06:12,780
from the simulator

117
00:06:14,400 --> 00:06:15,720
okay let me repeat that

118
00:06:17,340 --> 00:06:19,440
so here where we code the blocks

119
00:06:19,440 --> 00:06:22,500
are translated into text and this text

120
00:06:22,500 --> 00:06:24,660
is what I have copied and pasted

121
00:06:25,440 --> 00:06:27,900
over here to the arduino IDE

122
00:06:27,900 --> 00:06:29,040
program

123
00:06:30,780 --> 00:06:32,310
so now that I have this program

124
00:06:32,310 --> 00:06:33,810
this is the code I'm going to

125
00:06:33,840 --> 00:06:36,600
upload directly to the real arduino board

126
00:06:38,790 --> 00:06:41,220
so first we need to connect the

127
00:06:41,220 --> 00:06:44,880
arduino board to the computer with this

128
00:06:44,880 --> 00:06:46,380
usb wire can you see it

129
00:06:48,780 --> 00:06:50,400
now I'm going to connect it directly

130
00:06:50,400 --> 00:06:51,330
to the computer

131
00:06:53,910 --> 00:06:55,440
and now you can see the arduino

132
00:06:55,440 --> 00:06:58,680
board has some shining green lights here

133
00:06:59,610 --> 00:07:00,900
and over here so we know it's

134
00:07:00,900 --> 00:07:01,260
on

135
00:07:03,150 --> 00:07:04,590
so now the board is connected to

136
00:07:04,590 --> 00:07:08,069
the computer and I've opened the application

137
00:07:08,100 --> 00:07:10,350
arduino IDE and I'm going to

138
00:07:10,350 --> 00:07:13,500
upload the code to the first thing

139
00:07:13,560 --> 00:07:15,180
is to check that the program is

140
00:07:15,180 --> 00:07:17,760
correct so I click this checkmark and

141
00:07:17,760 --> 00:07:20,370
save it and down here it says

142
00:07:20,370 --> 00:07:22,560
there's no mistakes so it will work

143
00:07:23,250 --> 00:07:25,260
and now i can upload using this

144
00:07:25,320 --> 00:07:25,830
arrow

145
00:07:27,870 --> 00:07:29,910
and now the arduino board will have

146
00:07:29,910 --> 00:07:30,360
the code

147
00:07:32,070 --> 00:07:33,870
and if we look at the board

148
00:07:34,110 --> 00:07:35,850
we can see that the allergies are

149
00:07:35,850 --> 00:07:37,920
shining it looks exactly the same way

150
00:07:37,920 --> 00:07:39,210
that the simulation looks

151
00:07:40,860 --> 00:07:43,560
so to repeat I have programmed the

152
00:07:43,560 --> 00:07:46,380
arduino board using this usb connector to

153
00:07:46,380 --> 00:07:49,800
the computer and using the program arduino

154
00:07:49,800 --> 00:07:50,520
IDE

155
00:07:52,200 --> 00:07:54,270
then I pasted the code

156
00:07:55,710 --> 00:07:57,810
that was generated from the blocks

157
00:07:59,520 --> 00:08:01,500
and they are translated into code and

158
00:08:01,500 --> 00:08:03,390
this is what the program needs to

159
00:08:03,390 --> 00:08:06,330
have so now the real arduino board

160
00:08:06,330 --> 00:08:08,220
works the same way that the simulation

161
00:08:08,220 --> 00:08:08,640
does

162
00:08:11,730 --> 00:08:13,560
now maybe some of you are wondering

163
00:08:13,560 --> 00:08:15,870
or thinking that the computer is controlling

164
00:08:15,870 --> 00:08:17,730
the LED that are shining but

165
00:08:17,730 --> 00:08:20,160
it's not now how can I prove

166
00:08:20,160 --> 00:08:20,400
it

167
00:08:22,980 --> 00:08:27,750
because if we unplug the usb wire

168
00:08:30,600 --> 00:08:34,350
the arduino board would be off because

169
00:08:34,350 --> 00:08:36,390
the computer is providing energy to the

170
00:08:36,390 --> 00:08:39,780
board but what happens if i unplug

171
00:08:39,870 --> 00:08:40,590
this wire

172
00:08:50,940 --> 00:08:52,830
okay so here we can see now

173
00:08:52,830 --> 00:08:54,840
that the board has no energy and

174
00:08:54,840 --> 00:08:55,890
it won't work anymore

175
00:08:56,430 --> 00:08:59,400
but I can provide energy from somewhere

176
00:08:59,400 --> 00:09:00,960
else from a different source

177
00:09:02,250 --> 00:09:03,900
this wire here is coming from a

178
00:09:03,900 --> 00:09:06,180
different source of energy and we can

179
00:09:06,180 --> 00:09:08,760
connect it here and now the arduino

180
00:09:08,760 --> 00:09:10,560
is not connected to the computer any

181
00:09:10,560 --> 00:09:12,240
more but it has it's own source

182
00:09:12,240 --> 00:09:15,060
of energy and again the elegies are

183
00:09:15,060 --> 00:09:16,920
changing so it means that the program

184
00:09:16,920 --> 00:09:18,900
has been uploaded directly to the board

185
00:09:18,900 --> 00:09:21,900
and is stored in its memory okay

186
00:09:22,950 --> 00:09:25,500
so an arduino board is a device

187
00:09:25,500 --> 00:09:27,630
that can be programmed and it can

188
00:09:27,630 --> 00:09:29,160
run any program that you want by

189
00:09:29,160 --> 00:09:31,140
itself the only thing that it needs

190
00:09:31,140 --> 00:09:33,600
is a source of energy now and

191
00:09:33,600 --> 00:09:35,280
