2010年6月30日 · I purchased a few 74192 counters and a few 4511 BCD decoders. My intent is to have the 74192 driven by a 555 timer in monostable mode, that can be switched between the Up and Down inputs (a switch between Ground and Pin 2 would send a pulse to to input of either the Up or Down input of the 74192).

2015年11月27日 · 2. The first 74192 chip is preset to 9 and the 1 minute pulse is sent into the Up clock pin 3. While the 74192 chip is counting up it sends the data to 7447 and seven segment display 4. When the 74192 chip hits reset after 9 it sends a carry pulse to the second 74192 chip 5. The second 74192 chip starts at zero and counts up to 5 then resets to ...

2017年8月24日 · Good day! I'm making an up/down counter using 74192, 555 timer, 7447 and 7-segment LED. However, my counter starts at 1 but it should be in zero.

2016年1月27日 · Hi. I'm working on a project. A 24-Hour Digital Clock using 74192/74ls192 IC.There should be three buttons. 1.) Hour Increment Button 2.) Minute Increment Button 3.) Reset Button. The schematic diagram is fine but I don't know how to connect the RESET button so that it will reset all 7 segment LEDs to 00 00 00.

2019年11月29日 · I am using a 555 timer, six 74192 up/down counter chips, six 7447 displays, three AND gates, and six 7 segment displays to function as a 24 hour clock. I followed the data sheets and diagrams that my professor gave us but the seconds start counting from 60 and when it reaches 70 it restarts back to 60 and I can’t seem to figure out the problem.

2018年5月3日 · Hi, I'm working on a project to build a synchronous counter that counts up 00-99 and starts over using 74192 BCD decade counter, 7447 BCD to 7 segment and 7 segment ics. It is also supposed to have an asynchronous reset using a momentary switch. I have only used JK flip flops to build counters...
