Hello, I'm fairly new here. I have this little trouble. i need to do a timer that sends an impuls every 30sec from that I need it to go to a counter which counts from 0 to 9 and then resets back to 0. I can deal with the timer i just need the calculations for resistors and capacitors. The thing is that the only counter I know Is 74LS193D (multisim) and it counts to 15 and i only need to 9 and then it to reset back to 0 and go on agian. So i would like to know if any of you know a counter in multisim that counts to 9? Maybe the same 74LS193D does that but neads to load differently?
And there is one more catch i need to deal with is that I need the coounter to start at 0 when I give the impuls from Timer.
Because I need to make this project like it counts how much you need to pay and the first 30sec are free. So i need it to start at 0 then go to 1 and etc. But for me it starts at 1... So if anyone could help me with these questions I would be verry glad.
To sum up I need a counter that counts from 0 to 9 and resets back to 0 (the one I have done starts at 1 and counts to 15)
Please help me anyone ;/
