@@prachethire812 Thank you!!!!
@@prachethire812 Hi! I was wondering if you have something similar to that an easier one? With transistors too.
@@princessbaluca2284 This project was a consequence of experimenting with transistors to make a T-flip flop(aka push-on push-off switch), I didn't intended to make it. If you are interested in making "heads or tails" circuit with then there are many ways with transistors. I don't know which circuit is easier to make, obviously I will say mine is better but you are free to experiment and try other circuits. Thanks for showing interest.
I tried different ways but it doesn't work, neither with this ESP-01 or this ESP-01S I have. The only thing that I get when I reset the board is this set of characters through the Tx's ESP-01: ets Jan 8 2013,rst cause:2, boot mode:(3,6) load 0x4010f000, len 3424, room 16 tail 0 chksum 0x2e load 0x3fff20b8, len 40, room 8 tail 0 chksum 0x2b csum 0x2b v00040d90 ~ld The thing is that I get that when I set the baud rate into 74880 bps. When it is set in 115200 bps I just get garbage. I repeated this uncountable times and I get the same no matter what program I upload to the flash.
1. Don't select board as "nodemcu 0.9(ESP 12)" , instead of that select "Generic esp8266 module". 2. Initiate serial monitor by typing "Serial.begin(115200)" in the setup function. 3. Add a pull up resistor of (1K to 10K) to the reset pin. I hope the above three changes will solve the issue you are facing.
can you share the code?
Whats the formula to calculate the time of the output pulse?
... this used pnp transistors -_- ? And npn . I know how to made this but I don't have pnp transistor's
Phir Sir how are you????
I am good, working on IoT project.
Why we have oscillation of 1GHz ?
I assumed that propagation delay of not gate is in nano seconds, not sure exactly but it's small. If propagation delay is 1ns, on time = 1ns and off time = 1ns, Tp = ton + toff , frequency = 1/Tp , ie 1/2*10^-9 which is 0.5 GHz.
More such films!
very nice!
where i will get this kit?

how did you calculate the distance for detection?
*Promosm* 👌

Thank you very much! By the way we can use the pin 1 and 3 (Rx, tx) as gpio pins also
Yes, but disconnect from output devices and connect to Rx TX, while program is uploading
Buenas, puedes agregar el esquema

Ah, took me a moment to realize what the other chip was doing. It looks like you are using the 556 for debounce.
Yes you are correct.
What is the minimum detection distance ?

Thank you so much. Because of this i can finally continue making my project. And in future i will use this design only. Thank you so so so much
Edge detection can solve many problems in digital electronics like switch debouncing and toggling states. Apart from that you can use this wherever edge detection is required in your project. Thanks for realizing the potential of this circuit.
Sir can you make a cct with ultrasonic sensor and stepper motor using microprocessor? This video was very helpful to me. Very nice vid. Good work sir
What is a cct?
Muy bueno. Like dado
Wht are the components
I believe the output is actually like an h-bridge circuit to power the motor. There should be three output contacts, one +, one -, and one that is common. Get a pair of LEDs and connect them across the three terminals with one leg being common (cathode of one, anode of the other). Each should light up alternately for 1/2 second and so the combined "on time" is one second.
This is an amazing circuit and I want to build it. I need it for a project. Could you post in your credits a more precise schematic? I sure would appreciate it. Thanks!!

This circuit not work
Things won't work in first attempt and it's very common in electronics, don't worry. Pause the video on 7:57 and make the same circuit as shown, don't keep the load(LED's) connected. Use voltmeter instead of load. Use higher value inductor. All the best!!
Can I have the name of integrate?
Wow can I have the ciruit?
Nice! Could you share the code?
The code is specifically written for the circuit. Each character on the 16 segment display has a unique hex code. I haven't used any library. So without the circuit, the code is useless.

So it displays whatever you type?
Good presentation
Thank you!
Good job prachet
Thanks, this is 10*8, next I am going to make 16*31 led display, it has a good market.
@@prachethire812 👍👍👍
Flip flops right ? Very Nice idea😃
Thanks, by the way it's not flip-flop, it's a latch with delayed feedback. There is difference between latch and flip-flop.
You could have used a bi stable multivibrator instead .
A bi-stable multivibrator requires two switches, one for turning on and another for turning off. Now think, how can this be achieved using only one switch ?, such that when you hit it once it turns on and off on next hit.
@@prachethire812 true , not a feasible solution , although relays could do that , turn on one and another 📴. If you are an electronic enthusiast we could connect.
@@DevPatel-nf5mp Yes single button on and off can be achieved using two relays but circuit made by transistors are more better consume less current and less space.

Link dead?
Hello, I am interested in learning how to make this to fully understand how shift registers work. Do you still have the schematics?
That's great, that you want to make shift register and understand how it works. I can give u the schematics but first of all you need to know that shift registers are made by cascading D-flip flops. So first try making a D-ff using transistors. D-ff is nothing but a edge triggered latch. You can easily build a latch using 2 transistors. To make it edge triggered you need to watch my video titled "positive and negative edge detector using 1 transistor". I think it's the most viewed video on my channel, helped a lot of people.
The circuit diagram is not visible properly and also the link given in description is not working😕
What comes when you click on the every circuit link. Does it says " circuit does not exist".
@@prachethire812 yupp
@@paarthrane5229 click on the every circuit link again. Then it will tell you to enable native client. copy and paste this link on chrome address bar:- chrome://flags/#enable-nacl then enable native client. You will get to view the circuit with simulation. try from laptop or desktop computer if the option for native client is not available.
@@prachethire812 Actually my doubt is that... in the main circuit(consisting of transistors) the LEDs are responding to the motion of the scroller also when there are no transistors the LEDs are responding to the motion of scroller in the same way as in the main circuit....so my question is that what is the use of transistors if we can directly encode using just LEDs and the scroll
@@paarthrane5229 well I am glad that you figured it out,unlike the negative edge detector, the positive edge detector can be made just by a capacitor and resistor network. Transistors are just to amplify current and provide isolation in case you want the signals to be fed to some IC or microcontroller.
