1 00:00:05,000 --> 00:00:06,000 Hello, friends. 2 00:00:07,000 --> 00:00:11,000 Today I will tell you how to write. 3 00:00:13,000 --> 00:00:25,000 A signal or how to write through the analog output of any USB DAC 6001 using Python programming for 4 00:00:25,000 --> 00:00:27,000 that purpose, I just open. 5 00:00:30,000 --> 00:00:32,000 Python idle. 6 00:00:32,000 --> 00:00:36,000 And from here, I just open a new file. 7 00:00:36,000 --> 00:00:38,000 And over here, this is my new file. 8 00:00:38,000 --> 00:00:40,000 And over here we have the code. 9 00:00:40,000 --> 00:00:50,000 So first you have to just import deck Max, because already in the previous video I installed this API 10 00:00:50,000 --> 00:00:55,000 to my system with deck max dot task. 11 00:00:55,000 --> 00:01:05,000 You have to start a task and in this case, we have to just write a signal to a pin. 12 00:01:05,000 --> 00:01:07,000 That is my analog output pin. 13 00:01:07,000 --> 00:01:20,000 In this case I am using my device name is DEV1 oblique AO0AO stands for analog output over here and 14 00:01:20,000 --> 00:01:27,000 this is my channel and the maximum and minimum value shown over here that is maximum value is five and 15 00:01:27,000 --> 00:01:28,000 minimum value is zero. 16 00:01:28,000 --> 00:01:38,000 So over here I'm just start the task task dot analog output underscore channels dot add underscore analog 17 00:01:38,000 --> 00:01:41,000 output as a voltage through the channel. 18 00:01:41,000 --> 00:01:42,000 This one okay. 19 00:01:43,000 --> 00:01:51,000 Right now the value of the signal is two that I have to generate through my DAC card. 20 00:01:51,000 --> 00:02:01,000 Then you have to start the task task dot write your value and in this case value is two and task dot 21 00:02:01,000 --> 00:02:01,000 stop. 22 00:02:01,000 --> 00:02:12,000 So right now when you do this, the two volt signal generated at the output port of analog output port 23 00:02:12,000 --> 00:02:13,000 of the DAC card. 24 00:02:13,000 --> 00:02:14,000 Okay. 25 00:02:14,000 --> 00:02:16,000 So you have to just run it. 26 00:02:19,000 --> 00:02:20,000 Module five. 27 00:02:22,000 --> 00:02:27,000 So it will generate a two volt signal through analog output port zero. 28 00:02:28,000 --> 00:02:30,000 So in this case. 29 00:02:31,000 --> 00:02:37,000 So now I just go to my hardware part in the hardware part. 30 00:02:38,000 --> 00:02:44,000 As you see over here, this is my USB DAC card. 31 00:02:44,000 --> 00:02:45,000 6001. 32 00:02:45,000 --> 00:02:50,000 And over here I'm just connecting analog. 33 00:02:51,000 --> 00:02:56,000 One led to the analog zero port and the ground port. 34 00:02:57,000 --> 00:02:58,000 This one is the positive pin. 35 00:02:58,000 --> 00:03:02,000 This one is the negative pin of my LED. 36 00:03:02,000 --> 00:03:09,000 Right now the value is two volt because the threshold value of the LED is above three volt. 37 00:03:09,000 --> 00:03:11,000 So that's why it is not going on. 38 00:03:12,000 --> 00:03:16,000 So now I just change the value. 39 00:03:17,000 --> 00:03:17,000 Of. 40 00:03:19,000 --> 00:03:20,000 From 2 to 3. 41 00:03:20,000 --> 00:03:21,000 Let's check. 42 00:03:23,000 --> 00:03:25,000 It is right now. 43 00:03:25,000 --> 00:03:25,000 Three. 44 00:03:25,000 --> 00:03:27,000 So now just run it. 45 00:03:29,000 --> 00:03:30,000 It will ask me. 46 00:03:30,000 --> 00:03:32,000 You have to save the code. 47 00:03:32,000 --> 00:03:33,000 So I just put. 48 00:03:33,000 --> 00:03:43,000 Okay, So now as you see, the LED goes on in this case, right now, LED goes on. 49 00:03:43,000 --> 00:03:57,000 So if you want to off this led, you just change the value from below to below three let's it is 2.5. 50 00:03:57,000 --> 00:04:01,000 So again hit on run button. 51 00:04:02,000 --> 00:04:02,000 Save it. 52 00:04:04,000 --> 00:04:08,000 As you see it, is going off right now. 53 00:04:08,000 --> 00:04:11,000 My LEDs off in off condition. 54 00:04:12,000 --> 00:04:19,000 So as you see, this is in off condition or you can say it is running with low value. 55 00:04:19,000 --> 00:04:20,000 Okay. 56 00:04:20,000 --> 00:04:22,000 So this is all about today's lecture. 57 00:04:23,000 --> 00:04:23,000 Thank you.
