imagine I build this this device that takes in impulses... 0 and 1

but I need an interface with buttons to decide when to throw a 0 or a 1...

would java be a good language to control this?


I'm having difficulty to make this path...

interface to circuit...

if somoene can enlight me, i'd really apreciate it.


Jaime, thanks

It is possible to access devices e.g. via USB or other serial connectors. But Java is not a common choice if you want low-level access which may be a strong hint that it is not the best choice (for an arbitrary definition of "best"). At least the service to access the device would typically be written in C (or maybe ... C). Often, especially for simple interfaces, it doesn't make much sense to pull Java into the dependencies then.

so C would be a good choice to create an interface that some how

by clicking his button I will send an impulse to a certain part of my circuit?


where in my circuit would the program be stored?

let's say I got an interface with

Button A
Button B
Button C

each button has a different function in my circuit,

where would the program be stored? in some chip right?

does this matter have a name so I can see it on internet aswell?!

thanks

I am not sure I understand how you access your "circuit". Is it some basic electronic (even self burned) connected to your desktop or laptop via a serial port? Or is it something more capable like an Arduino?

Hauke, I dont have a circuit yet,

i'm trying to find a way to control a circuit trough a screen interface,

im a Java student, looking for an application of Java programing beside data treatment,

im not an informatic student, im an eletronic student(fresh one) , to give you a clue of my point.

for eg. I want to make some automatic courtains, and I want to close em by cliking the close button on my computer...
so if I could create that java program I would feel a little more realized with all I'm learning.


i've heard about arduino, although I dont know how it works.

can you control a circuit through your computer with arduino?






thanks for reply

Arduino is a microcontroller capable of running C programs on board and controlling actuators itself. It would replace any custom made controller (or circuit), at least for prototyping purposes. If you are an electronics student you probably will learn to build specialized controllers yourself. But for building working devices in quite short time Arduino is a nice tool. You could run a web interface directly on the board itself, no desktop needed at runtime. You would control the device via browser then.

But Java would not be involved in this specific scenario.

sweet! thanks for leading me to arduino, i've got some friends learning C,

and they say so far it's pretty simmiliar to Java on the basics at least.

for now, I will still try to get the most return of java programing ;)



thanks a lot for your time, I really appreciate that,
