Hello, we are Sara and Paula from the ISAC Albany, and we are going to present our STEM project that is a stick for blind people.

2
00:00:10,699 --> 00:00:22,359
To create this, to make this blind people stick, we had to use several codes, and this is one of the codes that we used at the very beginning,

3
00:00:22,359 --> 00:00:26,839
which controls the distance.

4
00:00:27,300 --> 00:00:33,259
So within a certain amount of distance, the stick beeped faster or slower

5
00:00:33,259 --> 00:00:40,079
to tell the blind person at what distance the object is at.

6
00:00:40,619 --> 00:00:44,780
Here is our code that we used to make this stick.

7
00:00:44,780 --> 00:00:54,399
um here you can see here you can see uh there's different time uh intervals for the different

8
00:00:54,399 --> 00:01:00,719
distances for example if the object is um closer than five meters distance it beeps at one

9
00:01:00,719 --> 00:01:07,459
millisecond and then depending on the distance the the time goes up because it's further away

10
00:01:07,459 --> 00:01:14,340
and this is the code because our our control board doesn't support auto

11
00:01:14,340 --> 00:01:24,260
blockly so we had to turn it into Arduino to make it work okay and so this

12
00:01:24,260 --> 00:01:36,019
This is the control board that is used for sending information.

13
00:01:36,019 --> 00:01:45,019
This is the ultrasonic sound that detects the distance between the objects.

14
00:01:45,019 --> 00:01:55,019
This is the actuator that is a buzzer that beeps when it is near to an object.

15
00:01:55,019 --> 00:02:02,219
and this is the battery to be an autonomic and now we are going to do the demonstration

16
00:02:18,169 --> 00:02:21,370
and that's it thank you and bye
