how do i make a computer control electronic device.?

Question

i want to make a device which attaches to the computer and operates as we command it from the computer. suppose i attach 4 bulbs and two motors to that device and a transformer used only for giving voltage supply to the bulbs and motor. now as i give a command from the com to start 1 bulb and 2 motors or all of them then it should start. technical explanation needed. thanx for helping

Answer 1

Simple. You can use the PLC Controller that interfacing with your bulbs and motors while control via computer using RS232 port. Some hi-tech PLC Controller control through a RJ45 plug.

Well, setup is always easier. But, you need to know the programming of the PLC prior to your success of your work. For motor, it is absolutely harder. If is a simple DC motor which does't more than the Output power rating of a given PLC brand you are choosen, then is no problem. But, for those motor that out of the rating, you may need to install contactors and relay to aids your sequence.

Microprocessors and Microcontrollers can purely administration particular issues without different circuit factors to help it out. for occasion, driving a speaker, maximum micros can't try this via themselves. they want an digital to Analog Converter. This takes the tips it extremely is stored interior the only million's and 0's and adjustments it right into a various voltage (what drives a speaker). some kinds of automobiles could be pushed a similar way, however the main consumer-friendly way of turning a motor with a microcontroller is what's asserted as Pulse Width Modulation. fairly how usually and lots aside the only million's and 0's are can trick the motor into questioning that's seeing an analog voltage, the farther aside the only million's are, the decrease the voltage the motor thinks that's seeing. so a strategies as understanding what device to administration, it extremely is desperate up via the programmer of the microprocessor/microcontroller, and the gadget fashion designer. All pins in a micro are assigned names, via connecting the device you pick for to a undeniable pin, all you're able to desire to do is call that pin call interior the micro's programming. for sure it extremely is an fairly consumer-friendly answer, maximum micros in recent times have particular good factors which you're able to desire to order particular pins to apply them.

Answer 3

You have two areas to consider here. First, the computer software to pass the commands to the interface, and the interface it's self. Consider how you use your computer to operate your printer, for example. Another example is how I use my computer to control the equatorial mount on my telescope. In today's IT world we now even have wireless interface to consider as well. This gives you the ability to remotely use your computer to turn those lights and/or motors on and off with out a wired interface.

Answer 4

Probably the easiest way for you to do this is to get a USB to serial port dongle , read up on RS 232 ( now called TIA 232) protocol and get your PC to control relays that will switch on the bulbs or motors as you wish

Answer 5

Your first sequence of steps should be to learn the basics of electronics and computer interfacing.

If you aren't all that interested, try searching the web for computer interface projects involving lamps, motors, etc.

Answer 6

Controlling devices from ur computer requires the knowledge of socket programming ... that is using languages like C/C++ nd by having knowledge of socket programming u can perform operations on ny peripheral devices attached to it ....!!!!
Socket programming is the programming of the i/o pins of the computer on which all the peripheral devices are attached ...
