Hey,
I am really sorry about this but the components to which i have made arrows towards i am not familiar with since they are not the same in my program of Circuit Wizard.
Do you mind just quickly stating which they are??
Im really sorry about this.
Sorry for the late reply.
I haven't had access to the internet.
This is my circuit, redesigned as per your attachment.
As you can see, it still is dysfunctional.
In fact, it has become worse than my problem before.
Is there anything that can be done??
Thanks

Hey,
Thanks for all your help so far.
I just got a couple of questions, mostly about the theory im guessing, along with some general problems.
First, the number on the 7 segment always starts at either 99 or 11, but never 00. Granted, i can press the reset, but is there a way to make it default on 00?
Add the cap across the RESET switch
Second, instead of two SPDT switches, is there a way to make it just one push to make on both end on the left??
The drawing shows two single pole normally OPEN push buttons.
Third, if one switch is on the 'top', not connected, only then does the other one work. If it is at the bottom, it doesn't. Why??
You have got it wired incorrectly!
Thanks a lot

hi,Hey,
You mate are amazing.
I just got one problem persisting.
When i start the circuit, the 7 segment displays 99 or 11. Any way to start at 00?
Hey,
See attachment
Hey,
Also, while your helping,
Is there a way to make an opto-isolator and a PTM switch both count up?
Perhaps with the use of PICs??
Thanks a lot
Hey,
Let me see if i can explain what i am doing.
I am building this project that is an electronic piggy bank.
It would detect a coin when an opto-isolator IR connection is broken.
I want it to input the output of this into a PIC which can generate pulses to count up a certain number.
For example, if a 5p coin is inserted, 5 pulses should make the 7 segment count up 5 times.
However, i also want 4 push to make switches:
Two for counting up (one for up in pence, the other in pounds)
Two for counting down (one for down in pence, the other in pounds)
This is why i have been asking you these questions.
What do you think??
Thanks

EDIT:
I had tried a PIC but found it difficult to count up and down. I use a GENIE PIC, the default microcontroller on circuit wizard.
Hey,
The PICs they have to offer are seen below in the attachment.
What you must know is that the top row are microcontrollers, and the bottom are DILs.
How these PICs work are on a flowchart basis, which may be what you have downloaded.
The micro PCB thing you were talking about may be the software Circuit Wizard. However, this program is not free to download unfortunately.
Is there any other way to detect coins?
Or go back on my original idea, which was to use 8 opto-isolators to detect a coin through special sized slots, which give an input into the PICs and then make a flowchart to output a certain amount of pulses depending on the input?
Note: There is no point uploading my [Circuit Wizard] circuit file as you do not have it. If you are able to come across it somehow, please state so and i shall upload it.
Hey,
I am sorry but the names of E18, E28 are what they are called.
They are special GENIE chips, as mentioned before.
Also, do you mind to explain what your idea was of using only one slot to detect all the coins?
Thanks
