@@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.

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.

I am good, working on IoT project.

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.

Yes, why not

Yes, but disconnect from output devices and connect to Rx TX, while program is uploading

Yes you are correct.

@@_Osman_Dag_ Very right

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.

What is a cct?

Yes, sure.

@@prachethire812 how do I get it

Connect wires to the rotary encoder. Rotary encoder is connected to the scroll wheel of the mouse. It is three pin component, solder wire to these three pins.

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!!

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.

@@prachethire812 Ok, thanks

So it displays whatever you type?

Thank you!

Thanks, this is 10*8, next I am going to make 16*31 led display, it has a good market.

@@prachethire812 👍👍👍

Thanks, by the way it's not flip-flop, it's a latch with delayed feedback. There is difference between latch and flip-flop.

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.

You're welcome, Hello from India.

Follow the steps given in the link, keep trying. Maybe it's a problem related to IBM Watson, try creating new account for the device. Also esp32 has to be made compatible with Arduino ide, have you done that?.

@@prachethire812 is there a way to send those graphs to any custom apps to view?

@@amanshaji4436 I don't know whether there is a tool in IBM Watson that allows you to create API But there is a site called "MIT app inventor" where you can create your own app.

It's not free.

@@prachethire812 what price this circuit

@@yashSharma-us8xj usually, you would interface HC-05 with a microcontroller and spent time coding the controller to achieve similar performance. This circuit saves your money and time. You make this circuit, credit me, and if the circuit works, you can donate money.

@@prachethire812 circuit diagram ka kiya price hain muje without microcontroller ultrasonic sensor use kerna hain

Today im happy Because this circuit after long time im complete thanks sir this video is very helpful for me

You're welcome. Feels nice to hear that.

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.

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.
