Youtube daily motor May 1 2017

okay so here's what I think it would be

fun to try to do. You know I've got my

program where the button turns the

motor on, and then I touch it again to

turn the motor off. I'm thinking it would

be fun to try to adjust the motor speed

while it's running with the motor is running with the

potentiometer. So that means I need to

be calling startmotor while the

motor's running repeatedly with

different motor speeds. Here's how I'm

going to tackle that. first of all I'm

going to change this untilTouch to be

to be different. I

copied the code that Ineed into my buffer earlier so

I'm going to paste it back in. I'm

basically going to replace this untiltouch(button)

with this while loop which will repeat as long as

sensorvalue[button] is equal to 0. Inside the while loop, the variable j is

set to 0 because the RobotC language won't allow an empty while loop. J is a variable and you

you have to declare your variables.

I'm going to put a comment. if I do

slash star and then end with a slash

star everything in between is a comment.

it's good practice to put comments to

explain what's going on. so I've

got this. let's just see if this program

runs, if I can turn the motor on and off

first. so I'm going to compile and

download, and what I'm hoping is that

this program runs exactly like the

previous program but if it works then

we'll be able to I control the

motor with potentiometer. so let's see.

the programs running so I'm going to

press the switch to start the motor, and press

it again turn it off. first to start it,

press it again to turn it off. so my

program is working. so now I need to stop

and what I'm going to do is inside this

while loop while I'm waiting for the

button to be pressed to stop the motor

I'm going to keep calling

startmotor over and over.

well first I'm going to declare a

variable speed. then

I'm going to come down and here I'm

going say speed is equal to sensor value[potentiometer]

to a number between

0 and 4095

I need to know what 4095 / 127 is so

4095/127 is a little over 32

so if I do

4,095 divided by 33 I get 124 that'll

be good. I don't want to tell it to go

more than 127 and then I'm going to say

startmotor(testmotor,speed) using the speed that I

just calculated. think I can delete

this and so by continually calling startmotor, it's not really restarting the

motor every time, it's just adjusting the

speed. I think this might do it so

let's give it a whirl. so if I do

I've got a variable int j that I'm not

using anymore so I'm going to get rid of

it since the compiler didn't like that. and I'm

going to download it

and I click start now. notice how

potentiometer is at 4095, so when I press

the button 4095 divided by 33 which is about

124 so I think this motor is going to be

running close to full speed. so I'm going

to press it and it's running now. if it

works I should be able to turn it down

by adjusting the potentiometer. look at

that. it's working, so I'm turning the

potentiometer and the speed is getting

really slow. hopefully you can hear that

I can probably almost stop it and it is

stopped. now I can dial it back up.

alright that's cool.

so it works. that's it so I want you to

see if you can get this program to work

yourself so I'm going to stop the video

General Motors Lordstown plant shutting down for 2 weeks in July - Duration: 0:38.

Production of the Chevy Cruze at

the Lordstown plant will be put

on hold for

another two weeks in July.

That's on top of a two week

shutdown

planned for June. According to

UAW Local 1714 President

Robert Morales, the layoff weeks

are being used to align

production with market

demand. He said some people may

be working at that

time, but didn't know how many

would stay on the job.

Production of the Chevy Cruze is

scheduled to resume July 17th.

GM eliminated the third shift at

the Lordstown facility ni

January and said it would

continue to build fewer at the

cars as the demand for trucks

and crossover
