Thread: Reg:java and robotics

Hai all

I don t know that question is correct or not,but also am asking

can i make a small dc motor to run through java programming language

if any, what are the requirements to do so?

how to do it?

pls explain me, i would be thank full for who help me.

Yes you can use java to control things like small dc motors. Java can be used to control just about anything around you.

I think "how to do it" exceeds the scope of a forum. I think the first thing you need is a problem to solve.
For example, my problem may be like the following:

I want to make my dc motor run when I press r on my keyboard.
Now there are questions like how will the computer communicate with the motor? Where will the motor get power from?.... this list gets very long very fast, so many options to consider...

So if you have an idea of what you want, explain exactly what you are trying to do and what you are stuck on.

Very very thanks for your replay

Actually i don't have any idea,my mind is blank about that.

(this is the scenario)
Assume that i have one dc motor,one laptop,connecting wires.
am gonna use head phone port to connect dc motor.
i would have JButton's to control the dc motor.
when i click start button the motor shud run and when i click stop button it shud stop.

is that any thing i need to learn more in java or any to achieve this.
if any please advice that all.can you?

Please explain more about:
"use head phone port to connect to dc motor."
I am not sure I fully understand your intentions yet.

I mean ,the port where we usually connect ear phone to computer.

is it possible to do?

I'm not saying an audio signal can't make a motor turn, but there is great risk of damaging the computer.
The audio circuitry was not designed to run a motor. The output is very limited.
What are you trying to do exactly? Why are you wanting to connect to the audio for this? Why not use the USB where there is power and data?(also limited and not designed to run a motor, but a greater chance than the audio)

Sure,i agree to use USB port to run the motor.but how? and which part in java need to learn for this?

I think the first step would be to get a clear definition of what is to be done.
Computers have many options in terms of output and those outputs can be interpreted in various ways.
Perhaps you should research first, things like what types of power is available from a computer, and what components can respond to the output you choose to work with.
Just for the record neither I nor this forum is suggesting that anyone plug anything into a computer for testing. There is a risk to the computer and people nearby.
Having dodged the legal department, I have a USB powered fan I made. Also you can look around, there are laptop cooling fans that run off USB. This line of thinking may provide you some answers
Don't give up... And if you break your computer, well it is just a computer right? I have probably broken one in the past at some point.

Thank you , i will try my level best
