Here is the circuit click here: There are lots of ICs you can use as a counter. And also, you can improve this circuit depending on your needs. This entry was posted on May 9, at You can follow any responses to this entry through the RSS 2.


You can leave a responseor trackback from your own site. If I want to use 3 7-segment what is the circuit or connection now?

But the confusing part is, where should i place my clock using function generator to supply frequency?? I am unable to get the circuit to work properly. How exactly do you wire up the 7 segment display, the current limiting resistor to the 7 segment display, and power to the 7 segment display?

Also, can I use a 74ls counter with the 74ls47 decoder?

If you have an opportunity to provide the full wiring diagram that would be great. Make sure that you use 5volts supply. Test first your using a switch.

If it does work, then your is not yet damage. I would like to 74os190n the circuit of the second video, do you have the complete schematic diagram?!

I am using a 74LS IC. My timer circuit already is working, i just wan to stop it when it reach 9 coz it will repeat counting from Pls give some advice sir, thx. You are commenting using your WordPress.
