24 second shot clock - Electronic Circuits Projects Diagrams Free

mitsui58 · 25th February 2008, 07:09 PM

can someone help me in building a 24 second shot clock with buzzer? the digits will start to blink when it reach 5 seconds. we need to use an 8086 trainer like a MTS 88.c to encode the program.

hope somebody can help me.thank

s!

Sounds like a homework assignment from 1986.

somebody help me pls..

Why do you need to use a 8086? How about a PIC, AVR or 8051? What sort of digits?
When's it due?

its a project for microprocessors laboratory..the trainer were using is an 8086..

the deadline of submission is march 12. were gonna use a 7segment LED to display the time..

hope you can help me..

What sort of help do you need? What don't you understand?

im looking for a circuit of the shot clock..i cant find one in the net..

You said it was some sort of 8086 trainer, it should have a schematic. Are you designing the device from scratch? What hardware software experience do you have. Can you find something similar on the net and post a picture?
Here's a shot clock schematic.

yup..from scratch..i needed to built an I/O board for the 8086. Our group choose to make a shot clock..
a schematic diagram of a shot clock..

i dont have any experience designing hardware

Then you're going to need to get some hardware experience before March 12, how do you expect to design a microcontroller from scratch and program it from scratch before then?

Well the 8086 is a microcomputer not a microcontroller. Not really a good choice for such a project.

i know a how to program the 8086 but i dont know how to build the circuit for the shot clock..
