Okay, I'm going to go ahead and change them to switches. So you right-click on here, in order to get a normally open switch. (clicking) And I don't really need the first one, so I'll just replace it back to push button. So hypothetically, when the robot arm moves, the sensors associated with each angle turn on or off. And they are presented by the switches we have here. I'm going to go ahead and go online, download the program, and then click on run. Then, I'll go to the binary table, over here, and I want you to see what happens once I press on the record push button. Remember, we will start loading from this bit. So now, I don't have any of the sensors moving. So I'll go ahead and I'll turn on the first sensor, and maybe…
