hello، Using a 10 kohm resistor is not a problem, but still, I recommend that you test the circuit with new resistors first if you are going to solder.
100 kohm resistance is related to IC pin pulldown and 27 k resistance is related to transistor bias and changing both to 10 kohm does not cause any problem.
Hello, thank you for watching this video The tachometer can also be connected to this circuit, the output pulse of the tachometer must be connected to the input of the clock IC.
Hello Thank you for watching this video One end of the push button is connected to vcc and the other end is connected to pin 15 of the IC. Also, pin 15 is connected to the ground using a pull down resistor of 100 kilohms
Hello, thank you for watching this video, you should check a few things: First, check the direction of IR LEDs, then make sure the output pulses of the transistor. Make sure the pulldown resistors of the reset pin and pin 1 are connected. Also, the seven segments must be of common cathode type.
You can add an LED to that circuit and another display so that when it reaches twelve, the display you added can add one digit and the LED is so that it opens when it adds, please add to twelve and twelve, please.
Hello, thank you for watching this video It seems that the IC cannot count some of the pulses, maybe the problem can be solved by changing the IC. At the same time, check the IC reset circuit
Hello, dear Shimolyshah You can separate the pulse generator circuit from the ICs and manually give the pulse to the circuit, by doing this you will find out which part of the circuit is the problem.
I've made a circuit using your schematics but my IR seems to not working. Receiver is turned on bright and the seven segment shows improper count and is steady. Can u plz help me with this?

@@xselectroniccircuits6290 Now my IR's are working since I directed them towards each other, but they are not catching signals properly. They work only when they get touched or else.
You place the two IR LEDs at a distance of 0.5 cm from each other. In this circuit, the LEDs do not need to face each other or stick together. I suggest that you first disconnect the circuit from pin 1 of the IC and connect the collector of the transistor to the cathode of a normal LED and connect the anode of the LED to the positive voltage with a 1 kohm resistor. In this case, when you bring an object close to the IR LEDs, the normal LED should turn on, otherwise it is off. If this part works properly, you can remove the LED and connect the IC. I think you have a small fault in the bias circuit of the IR LEDs.

Hi big. May I use the transmitter or tv remote control (led wight) in this réalisation projet. Thanks and I have three digits associated in one block how can I use it if it is seen possible instead of two separate digits as you did in your video.
Yes, you can use the LED of the TV Transmitter. Also, to connect three digit, you must add a 4033 IC and connect pin 5 of the second IC to pin 1 of the third IC.
Hi Rahmano. Yes, A three pins receiver can be used for this, but the circuit of the transmitter and receiver needs to be changed. Please give me your email, I will send you the photo of the circuit.
Hello, thank you for watching this video The element that is rotated by hand is the potentiometer, which changes the frequency of the IC clock pulse and makes the binary counter count faster.
Hello, thank you for watching this video IC 4511 cannot be used instead of IC 4033, 4033 is a counter that works with pulses and adds one to the counter for each pulse and then displays it in the form of seven segments. But 4511 is a binary to seven-segment converter, that is, any binary value you give to the IC will be displayed in seven-segment format and it does not have the ability to count pulses.
Hello, thank you for watching this video You need to check a few things: first check the IR LEDs circuit is not open and the output transistor is generating a pulse, then make sure the pulldown resistors of the reset pin and pin 1 are connected. finally if it still doesn't work, replace the ICs
If i use 10k ohm resistor instead of 27k and 100 k in the circuit will it work?

IR module sensor
I need response asap please 😅
Hello, thank you for watching this video Yes, the IR proximity sensor does the same thing and can be used
Pay attention to this point that the voltage range of the output pulse of the sensor matches the voltage range of IC 4033.
When it reached 10, 20,30 and etc. the 0 will not appear and it directly proceed to 11.
