THANK YOU SO MUCH !!! ....... please continue to make videos like this ! the way you get directly to the subject, and step through things from paper, to hands-on ....... it's just the way it should be. .......there are a lot of other video hosts who do not have your talent for making clear and practical statements. even the most professional videos i have seen -all start with 20 minutes of "how a transistor works" or some other curriculum-based word parade.... .....shucks, in less than ten minutes, you had already taught me what they never did. Thank You, very much. FIVE STARS !

Ive been second guessing myself all day whether my D flip flop is working the way it should. Thats a good idea using a momentary switch with a light, and an indicator light for input D1.

Your diagram doesn't have a ground on the switch. Is this correct?

it didn't work for me because of this, my LOW input on the clock wouldn't drop below 1.7V

I need to get a few of these chips on the breadboard and have a play around. Flip flops are often already incorporated in other chips so their function is kind of taken for granted I suppose. That's the reason I keep harping on about getting back to basics!
@learnelectronics7 жыл бұрын
+gartmorn The entirety of simple logic is found in modern microcontrollers. When we write an Arduino sketch that takes an input from an LDR and uses logic to determine whether or not to switch on an output, we take that for granted. In reality there are many logic gates that are in the MCU to allow this simplicity. I like to know how and why they work.

A little confusion is there,two green LED on pin 2&3 should not glow because their cathods are positive biased as seen in your note sheet drawing.on pressing push button pin 3 &LED anode are at positive potential and LED cathode is also at positive potential.please clear this confusion..
@LostInLeiden2 жыл бұрын
I agree, this doesn't make sense, the LEDs on pins 2 and 3 should surely be attached to ground?

Could I use one to control 2 SSR relays with a 555 timer. I already have a 555 circuit that I want to use. I want one relay on when the output of the 555 is high and the other when it's low. I want to charge and discharge a large capacitor. Each relay only draws 9ma or Less at 5v. Can you wire the flip flop to switch high and low with the output of one 555? Or could I just cascade two 555 timers? Watch your videos all the time. Very helpful! 👍 Just wanted to add. I know I can do it with just the 555,. but I have the 555 set to have adjustable pulse width.

A bit more complicated. Could be used to set an alarm if the clock signal was literally from a 'clock'? Then in accepting the alarm you could re-arm it?

@learnelectronics7 жыл бұрын
+Michael Padovani any circuit that "processes" data is full of flip-flops. Like I said in the video a flip-flop is a one bit memory. What makes it useful is it is tightly synchronized to the system clock. This allows the flip-flip to wait for other logic elements to stabilize their results, then on the next clock cycle, the results are stored in the flip-flop. Processor speed is highly related to flip-flops.

hello! i don't expect you to reply to what i am about to say, but i'll give it a shot. So, the clip is very helpful, and i like the way you explained how a Digital Logic: D type Flip Flop works. The thing is that i need this chip, the 74HC74, to implement something for a project for school...And i don't see how i can do it...I have, by connecting the board to an Arduino board, to make two leds do these things: at 1 second, the first led should be high(brightened), and the second low. At 2 seconds, the first led should pe high, and the second high as well. At 3 seconds, bouth of them should be low. And then this actions should be repeted in a loop. I have to do this by using only one port from the ARDUINO board, like you did in this clip with the 2pin(the D input), but i don't see how i can keep the bouth leds high at the same time. Sorry for my bad english...if you could help me...that would be amazing!
@LostInLeiden2 жыл бұрын
I'm afraid I'm finding the results unrepeatable, can you help? Firstly the LEDs on pins 2 & 3 should be attached to GND and not Vcc (this is incorrect in your diagram but correct on your breadboard), so I have followed this right. When I press my button at pin 3, it goes momentarily HIGH (to 5V, lighting the LED) but when I release it, it should be LOW (it needs to drop
@LostInLeiden2 жыл бұрын
Turns out my pin 3 always floats at 1.7V (enough to trigger it HIGH). So I reworked my circuit so that my push button takes pin 3 to ground and when released it triggers the positive edge. So good news that my version of your circuit works, but I still don't know why my pin 3 floats at 1.7V, any ideas?

Can anyone help me do it so that the state changes everytime a clock pulse is made. the data pin would be set low and everytime a button is pushed the Q would toggle. Basically how do we do it with a T flip flop..... thanks in advance
@FreddieTheRobot2 жыл бұрын
Connect the !Q output to the data pin, and make sure pre and clr are always high. Following the logic table on a d type flip flop datasheet, with this configuration, !Q (and D) would always be the inverse of Q, so any time there is a clk pulse Q's state would change.
