Thanks a lot bro❤. But I have two question. 1/What if I don't use the preset? Isn't it just speed up? 2/Why you didn't use any logic gates?(i.e. AND, OR)

@its015 4 ай бұрын

If you don't want to use Preset then you will use approx 4.7 Kilo Ohm resistor instead of Preset.

I used logic AND gate in this video. In this circuit, three 1n4007 diodes and one 100K Resistor work as AND gates.

@@its015 ok. So if I use a 3-input AND gate instead of 3 diodes and a 100K resistor then the display will show 1 to 99. Am I right?

@its015 4 ай бұрын

@@picachuface no, If you want to Count 00 to 99 then no ned to use any AND Gate.

i have question sir why my circuit not counting? what part of component use to counting the number automatically?

@its015 4 ай бұрын

Check Circuit Diagram. Link is in the description box.

Another question is, if I make 1 to 99 instead of 1 to 60 seconds then the circuit would be less complex?

@its015 4 ай бұрын

Then these diodes cannot be used.

If I want to add at least one logic gate then where should I put it? Thanks you again.

@its015 4 ай бұрын

3 input AND gate should be used instead of three diodes.

What is the use of self lock switch kindly answer what if we use a push switch will. It become a counter?

@its015 4 ай бұрын

yes, If you use a push switch, it will act like a counter.

Hello bro. What if I don't use any resistance(connect it with just a wire) for common cathode connection? Will it damage the 7-segment?

@its015 3 ай бұрын

Yes, the possibility of 7 Segment Display damage remains.

@@its015another question. It might sound silly but is there have specific pin diagram for the 50K preset? I mean which side is 1,2,3?

@its015 3 ай бұрын

No, there is no specific Pin Diagram. Middle pin of Preset is Adjustable pin.

Bro i have used a simple switch so it becomes a counter if i use a self lock switch will it run automatically Plus it is going to 99 instead of 60 but the number of 1 7 segment cathode is not displaying properly How can i set this and restrict it. To 90 Plz answe

@its015 4 ай бұрын

Check your self lock switch with the continuity mode of the multimeter. And check the seat of 1n4007 diode

Bro I have applied as you have applied on breadboard just one switch is used I will remove it with self control switch then let see
