Go to lab 7 RC servo RC So it was demonstration.
If you look here at the I've got the breadboarding here.
I've got my three point three Volt to five volt conversion going on.
I've got the two 39-A four transistors in there and I've got my four resistors the two one k on resistors
and I've got 2.2 K on resistors in there as well.
If you look at the circuit diagram I talked about in the video you'll be able to find a reference that
schematic there.
And here we go.
Here's the bases to board with RC servo land completed and running on here.
And what I've got here is you can see the 7:7 display this is displayed what my pulse with modulation
output is in relation to the resolution.
So we've got 8 bits of resolution meaning that this value will go from zero all the way up to that.
And here I've got.
You can see the 5 volts I'm pulling off of the bases is too bored to power the RC circle.
And over here is brown wires the actual pulse with modulation output coming out of here and into the
3.3 Volt to FEIBEL conversion.
And this right here is a ground I'm pulling off here just to keep everything together and this right
here is the actual servo.
And so what I want to do here is I've got my Nabl pen which is low.
So right now my output is enabled.
And this right here is.
So it should add purchase here.
This should add up to five and this is Archie sort of a new push that a five year seniority servo that
just changed position.
So I keep pressing this because this is my nick right here I've got this switch locked into one which
means that's going to add and my value will change on here.
So as I keep pushing this value changes hands as that increases this won't change.
Now I'm going to go ahead and go down down values who's down on the arse's servo.
Now this thing goes all the way up to the RC service is limited in that it only has 150 degrees worth
of rotation.
And so I can't go up any higher.
Like you'll see what happens.
It'll keep falling until right now which is kind of the Maxson where we went down to zero.
So if I go in here it's kind of all in back around and nothing's going to happen here because this artillery
is an x value.
So I have to get back down to lower pulse with modulation values to where it'll start recognizing.
So yeah.
Now now of a second of these guys or I can push this is the one button and I push this year to a smaller
increments is larger increments and this enable although I couldn't put this off to say that this works.
Put that off because it's output.
I can push it.
But Holsworth modulation up it stays locked in.
But I can't press it on anything else.
Now enable again and as you can see switches around and counting down so you see and you'll be able
to tell it's working right away see you push your buttons here and you the hexadecimal map you'll see
the numbers changing.
Let's get down to value go see something wrong.
And also to since you hook your Cicero and you'll see the push button you'll see it kind of change using
his ups and down and once you going on you've successfully completed you.
