Hi.. thanks for watching. Do subscribe and share. Stop! Interesting one.. try to implement the following and let me know. At present the reset logic is made up of logic gates I.e. combinational logic. You can use a D flip flop, connect out of FF to the MR of counter IC. Make sure that the logic circuit trigger FF and changes the state which resets count continously. Or You can also think of some circuit to stop clock signal, as a result of removing clock will freeze the counter.
I'll leave the answer in case somebody will stumble on this and they are in need of an answer: To make the counter stop at any number or letter and reset you'll have to use a logic gate accordingly that will output into a MOSFET(quick description: a button that gets triggered if it receives current). The mosfet will replace the button. The logic gate will need to match the outputs of Q(0-3) ( example: if you want to reset at 0 just add a 4 input AND gate)
BCD counter that produces a four-bit output representing the BCD code for the number of pulses that have been applied to the counter input. For example, after four pulses have occurred, the counter outputs are DCBA = 01002 = 410. The counter resets to 0000 on the tenth pulse and starts counting over again. In other words, the DCBA outputs will never represent a number greater than 10012 = 910. Design the logic circuit that produces a HIGH output whenever the count is 2, 3, or 9. Use K mapping and take advantage of the don’t-care conditions.
Hi.. I'm sorry. I can't help you out. But, I can suggest you to learn about Microcontroller such as arduino or msp430, then use appropriate sensors and actuators to complete the task. Wish u all the best.
Hi.. do subscribe and share. good question.. both 7 and 4 are wrong. 1. Actually 7 segment hardware has ten pins. 8 leds I.e. 7 segments and 1 point plus 2 positive or negative. If common anode you have to connect common pin to positive supply. Remember you have to use a resistor on each segment led pin. 2. What you said 7 is theory model 3. What I used is ready-made model available in simulation. This can be considered as 7segment display plus 7447 ic connected together. For all electronics components do refer to the datasheet.
@@amnanawaz815 74193 --> 7447 --> 7-segment display. Note, the clock has to be triggered for counting purposes. You may use a clock source available in the lab. If not, you need to generate a clock signal with the required frequency.
It's called as pull up resistor. Basically 4.7k to 10k range resistor is recommended. When the switch is not pressed, input to the ic is floating, hence we need to keep it logically high. The resistor does that job.
is it possible to make it stop at 0 and not reset?

Hi..thanks for watching.
You may not get direct solutions for your assignments.
Thanks Thambi
implementation of 12 Hour clock (Hours Display only) using flip flop. can you do it?
Yes. You can do that by cascading multiple counters with reset logic. If you want me do it... sorry sorry
Sir can you help me ı have an assigment
I have to do automatic air conditioner
What should i use?

It counts only till 4 and again starts from 9
Sir 7 segment display has 7 pins.
How is the 7 segment display in video having 4 pins?

Sir so what to do while working on hardware?
Do I have to connect 7447 ic to the 7 segment and then with the 74193 counter ?

Which software did you use sir?

What is the use of resistor here ?
It's called as pull up resistor.
Basically 4.7k to 10k range resistor is recommended.
When the switch is not pressed, input to the ic is floating, hence we need to keep it logically high. The resistor does that job.
How to connect IC 4017 to Led 7 Seg , please
Check the datasheet of cd4017, I believe it is not going to serve the purpose.
please show us how to cascade them with up and down count.
