Nick Williams 1, 3 11 I wonder if this can accomplish this for us Although it will be difficult for you initially; your professor is doing you a favor by forcing you to read the datasheets.
The original description page was here. Author Swtpc at English Wikipedia. As echad said look at the datasheets and have a go at a schematic of a and 74LS connected id. I’ve tidied the formatting a bit but one reason homework question often “end badly” is when they don’t show any attempt to solve it yourself.

The parts would be: Retrieved from ” https: From Wikimedia Commons, the free media repository. So we have some knowledge about that chip; what about the timer? However, since you are probably not accustomed I admit, I’m not ideal at reading them to going through datasheets, I’ll try to guide you through some logic:.

A google search for 741192 Timer datasheet” once again proves reliable: We do require a clock for the 74LS Swtpc grants anyone the right to use this work for any purposewithout any conditions, unless such conditions are required by law. It appears, that there is a count up mode.

In some countries this may not be legally possible; if so: Once you get a job, you’re going to need to learn how to do this on your own.
The 9 LEDs will blink counting in seconds particularly 9 seconds then it’s going to loop from the beginning to start the counting again. Interesting, it’s a decade counter; but what is a decade counter?

Even if you get a few things wrong it’s likely to come across better and at least show you’ve made an effort.
Have you tried reading the data sheet? Well it sure seems as though this chip is pretty useful!
