1 00:00:04,640 --> 00:00:13,250 ‫Welcome to the tilt sensor interface demonstration with the ardy the seven I have the tilt sensor setup 2 00:00:13,340 --> 00:00:19,790 ‫on the breadboard where I have a slide switch that used use to indicate whether you want to enable or 3 00:00:19,790 --> 00:00:21,860 ‫disable the tilt sensor. 4 00:00:21,860 --> 00:00:31,940 ‫We have the actual tilt sensor itself as well as to 10 ohm resistors and the P.W. am enabled buzzer 5 00:00:32,710 --> 00:00:38,510 ‫on our already bored Arty's the seven board we have the interface running on there which is actually 6 00:00:38,570 --> 00:00:46,340 ‫utilizes a P.W. and module that we're feeding the enable signal which comes from this switch which we 7 00:00:46,340 --> 00:00:52,910 ‫can select whether we want it to be pulled up to high through the 10:2 resistor or have it connected 8 00:00:53,180 --> 00:00:57,620 ‫to where it's pulled up to high through the tilt sensor. 9 00:00:57,620 --> 00:01:02,240 ‫Now if we output at zero we're going to enable the tilt sensor. 10 00:01:02,390 --> 00:01:07,760 ‫And if we output a one we're going to disable the tilt sensor and then we also have coming out of the 11 00:01:07,760 --> 00:01:09,580 ‫jayvee port. 12 00:01:09,680 --> 00:01:15,400 ‫We have our enable signal coming in as well as our P.W. and output coming out. 13 00:01:15,770 --> 00:01:22,970 ‫And we also are feeding our power from this JTP port the zero and three point three volts into the breadboard. 14 00:01:22,970 --> 00:01:28,940 ‫So right now if we have the switch turn to disabled where we have it to the Pentium resistor pulled 15 00:01:28,940 --> 00:01:29,670 ‫the high. 16 00:01:29,780 --> 00:01:31,800 ‫We're going to constantly be putting a one. 17 00:01:31,870 --> 00:01:37,950 ‫So no matter if I tilt or not you won't hear anything. 18 00:01:38,120 --> 00:01:42,720 ‫The buzzer will not buzz and that is because we have it constantly set too high. 19 00:01:42,740 --> 00:01:47,430 ‫So whether the tilt sensor engages or not it's not going to activate. 20 00:01:47,600 --> 00:01:53,840 ‫And when you tilt that you can hear the actual the two metal balls inside the tilt sensor can you'll 21 00:01:53,840 --> 00:02:00,020 ‫hear them roll to show that you're going to make contact and disconnect where you won't have contact. 22 00:02:00,260 --> 00:02:02,600 ‫But your buzzer won't do anything. 23 00:02:02,600 --> 00:02:10,420 ‫So now go ahead and enable the we're going to be able to tilt sensor by sliding a slide switch and right 24 00:02:10,420 --> 00:02:15,540 ‫way we should note that we're not hearing a buzz and that's because we haven't tilted just yet. 25 00:02:15,560 --> 00:02:21,800 ‫So when we tilt will reach a certain point where the two metal balls inside the can will no longer make 26 00:02:21,800 --> 00:02:29,360 ‫contact and we'll point to zero through the 10 tailed resistor and that will enable our P.W. signal 27 00:02:29,420 --> 00:02:31,700 ‫which will then sound the buzzer. 28 00:02:31,910 --> 00:02:40,410 ‫So go ahead and I'm going to tilt the tilt sensor and you should hear that. 29 00:02:41,000 --> 00:02:46,120 ‫After a certain point it'll output a buzz sound and you kind of tell this based on. 30 00:02:46,120 --> 00:02:53,180 ‫It won't go off won't go off and then all of sudden you reach a certain point where the buzzer goes 31 00:02:53,180 --> 00:02:53,600 ‫off. 32 00:02:53,630 --> 00:02:56,100 ‫And that means your tilt switch has engaged. 33 00:02:56,180 --> 00:03:00,080 ‫And so this can be used in different types of applications a security application you want to make sure 34 00:03:00,080 --> 00:03:01,510 ‫a device doesn't move. 35 00:03:01,520 --> 00:03:06,270 ‫Now instead of sounding a buzzer you could do other things such as send yourself an alert. 36 00:03:06,380 --> 00:03:13,510 ‫But this is a demonstration of how that tells us the interface is running on the the seven board.
