Hello everyone, ive been reading some threads over the forum and i tought this was the perfect place to learn more about eletronics and to help with some doubts i have.
It was proposed to make a frequency meter using the following components:
74ls47
74ls273
74ls193
ampop - zero detector
ne555 - monostable
some inverters to delay the clock over the 193 and 273
So far i got this done:
I got in to the following problems, from the right to left the display counts but it apears the hex code after the 9 digit and adding the ampop with the 555 to detect the frequency and show on the display it only shows me trash over the display and not the frequency i added on the signal generator.
I would apreciate if anyone could help me with this since ive been going around this for a while and i need it done by the end of the year. NOTE: im new to the eletronics but im willing to learn and absorb any knowlege you guys could have.
See you soon.
