Hi there, i could use some help with an Electronic dice. I have built an A-stable, got the counter (4517) and the decoder (4511) wired up correctly, however there seems to be some interfacing problems, as it dose not work .
I know it is a simple circuit, but i just cant get it to work! If you could help, here is what i wanted it to do;
Count from 1 - 6 (hence 4517 - for the preset to 1 reset)
Count at 1000 times a second (i have already worked out how to do this with a 555 astable)
Be able to freeze the number it is on at any time by pressing a button (whenever i try to use a button, it randomly changes the numbers on the 7 segment display, usualy not even to number patterns :roll:
Oh, and how could i get the counter to stop at 6? i tryed having some and gates make the reset high when it go to 7 in binary, but it didnt work
