To Short or not to Short- that is the question

[SparkyCal]

Can someone help me interpret this schematic below

My question relates to Pins 2, 3 and 4 on the 555 Timer.

Does this schematic require that Pin2 be shorted to Pin 3 and pin 3 be shorted to Pin 4?

I am thinking not but I am not sure.

Thank-you

No, if connected together there is a round dot joining them.

No, if connected together there is a round dot joining them.

In this style of diagram, only dotted crossovers are connections.

BTW: the unlabeled input on the flipflop [from 55 pin 3, to "tact" momentary pressbutton] is probably labeled "CLK" or clock on the data, pin-out.

Thanks guys. Just learning about flip flops. I breadboarded this tonight but it failed. Likley because it is not well labeled in certain spots. I'll try what you suggested Naren888

I breadboarded this tonight but it failed.

Which type of JK-FF did you use? Which pins did you connect? Show us an annotated complete schematic diagram.

I need to re-do this. I did it while tired and rushed and that probably accounts for thre failure. if it fails again, when i re-do it, i will post it

Thank-you

Hello,

You will encounter different types of schematics.
These pictures show the difference between the old method and the new method for drawing a schematic crossing:



This can be confusing, so take a good look wich method is used.
