Each of these monolithic counters contains four master- slave flip-flops and additional gating to provide a divide-by- two counter and a three-stage binary.

Jan 4, 3 0. But when i open the key resetting key while the first 7segment runs properly the others instantly jumps from 0 to 1.
Its all on the data sheet. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Interpreting Current-Voltage Curves of Different Materials This article discusses the ideas involved in measuring and interpreting the current-voltage curves of solar cells, batteries, and unknown materials. Mar 31, 23, 7, Jan 4, 3.
I did it by myself the first part from 0 to Potentiometer Questions Started by norbss Yesterday at Jan 2, 3. Fine but i want to 1- Make it 0 to 5 for the parts of 60 minutes and 60 seconds.
Have you downloaded and read the data sheet? Another thing you might look at is just using a single counter and having your buttons either increment or decrement it.
Actually im a new starter in digital, trying to learn n do all by myself. Here is what i have now: It also looks like both counter’s will increment on a button press. If used, you can preset the counter to any valueand it will count-up from there.
Then you can add the AND gates to get things to roll over as minutes: This work need to completed by tomorrow. Jan 4, 7. Can you help me with this? Your name or email address: And there is no problem when i do not use and gate in 2nd counter and it counts from 00 to 99; which means voltage of the carryout of the second counter is allways positiv escept drops to 0 at 9 and rises again at 0 which sends the triggering to the 3rd counter So how can i owercome this problem?
EfeVural New Member Jan 13, One think i thought to sychronize is to give voltage to reset input of Jan 3, I want to create a clock in multisim i created the circuit attached.
This will provide a nice clock signal for the next counter.
I would like to know how to connect inputs of LS and how this counter works, because i dont understand anything from datasheet: Yes, my password is: But i am not being able to create a Pause nor Reset Function. Now the question is how to make to count from 0 to 10 datsheet 2 indicators?
The AND gates is keeping the timer in control and the min: EfeVural New Member Jan 28, Get it working just counting normally 1 to Hello, ONE thread is enough: The output of that can be used to drive the display for the number of spaces taken and then you can use an adder to subtract that value from the total number of spaces to get the value for the other display.
How to use a LS as a counter with button | All About Circuits
Jan 3, 9. Hello, I have reduced your picture from 5. Jan 3, 5. The carry out ‘CO’ to clock helps the ics to interoperate and keep the track of time stay in order. Welcome to our site!
Feb 19, 4, If i dont use and gate then the seconds go to 99 and after that minutes becomes 1 and seconds I used reset also for sychronizing the first “Zero”s 00 in order not the mix two resetting ideas i used or gate i connected a key to reset both oh the 7segments when i open the key the circuit starts from How to use a LS as a counter with button Reply to Thread. No, create an account now.
Then i push first button, green indicator should count up by one, and red indicator should count down dafasheet one. Started by fastline Yesterday at 8: There were some solutions suggested with preset inputs; however as i understood, the function of the presets is that they decide the beginning number of the count. I mean of sychronizing as i attached. Apr 11, 3, 1,
