Hi

I am a postgraduate student and a beginner in micro controller

I need to design a PC interfaced electronic circuit to control relays. I feel switch design is straight forward. I got struck in interfacing the switch with PC.

Is it possible to do with micro controller ?. If it is yes could you please let me know the cheap Micro controller with basic capabilities ?.

I prefer USB interface

Regards

Faisal

Maybe a stamp module or arduino is what your looking for, google those two (They are both usb).

I don't know about the ardunio but the Stamps are RS-232 [DB9] serial...

Hi

Many Thanks for your response.

I will explain my requirement more clearly. I have done Intel 8085 programming during undergraduate course. It was 10 years back.

Now I need to control relays via PC which means PC will send a command to an electronic circuit to energize relay coil and PC will send other command to deenergize the relay coil. Electronic circuit and relay is straight forward. I can do that.

My problem is how to communicate electronic circuit using PC.?

I guess micro controller together with PC can do that. Is there any alternate solution ?

If it can be done with Micro controller , I need to get familiar with Micro controller first. Can you suggest me where to start with micro controller?

Regards

Faisal

Try here if you like the Microchip PICs.

A vote for Arduino. Communications with PC is very easy even for beginners. PIC has great flexibility that you probably do not need.

If parallel port is available, you can directly control relay from that port without using microcontroller.
