thats my code tbh all i want it to do is literally power pin 3 up and make all the common cathodes of all digits except 1 so they dont light up powering pin 3 goes through my binary decoder and translates it to wire 8 which is supposed to power the . in the last digit. when i directly short pin 3 to VCC of arduino the . lights up without issue but when i use "1" and power it with code the chips go broken oh that yeah it probably just kept re-writing the same thing and lagged it out. so i am asking, why do the chips get broken only when powered with code. direct circuit short works fine. remixing :P possibly. its misbehaving. so i either have to switch to real hardware or just use another sim? why do you think i do not know what i am doing? i am pretty new to multiplexing, if i am being honest. but im pretty sure i know what i'll do, considering i have built clocks before. what i am doing this time is just adding ms digits to it and multiplexing in an effort to manage to use an arduino UNO when i build it physically, even with more pins to manage from the segment displays. well, maybe. but this thing is just something really unoptimized i am using to test out my wiring. though, you really helped. thank you for it.

Sorry, I was out for a work. What's the update? @myzstral https://discord.com/channels/420594746990526466/451155251580633089/1391361219276967936 I got your response, but I don't understand the usage of 3 AND Gate ICs

myzstralOP•3mo ago

its used for my multiplexer iirc i gave u a link to the multiplexer i took insipration from https://discord.com/channels/420594746990526466/451155251580633089/1391362186101653548

DarwinWasWrong•3mo ago

Do we have a link to diagram or emulation?

myzstralOP•3mo ago

^^^ check that link and you'll see what the AND gates are for i forgot to add it, sorry adding it rn

i cant pin it :/

Coder_DO_As_Impossible•3mo ago

Ok, I got it, but I don't understand then the usage of HEX decoder.

myzstralOP•3mo ago

its used as NOT gates

DarwinWasWrong•3mo ago

Have you tested one digit by itself ? Without multiplex

Coder_DO_As_Impossible•3mo ago

Hmm...

myzstralOP•3mo ago

wdym one digit itself it does work like as i said even with multiplex direct short circuit through a resistor to arduino's 5v works but when i send the signal from the arduino through code, even with the resistors, the chips break its probably the sim just misbihaving

DarwinWasWrong•3mo ago

In real life ? nope ok That is on VERY hard cirduit to trace....

myzstralOP•3mo ago

either because of my horrible wiring or the multiplexer that has a few million wires connected to it yes

myzstralOP•3mo ago

i mean it does work even though it shows the chips "broken"

myzstralOP•3mo ago

i mean i tried making it as easy as possible by using as much colours for wires as possible

Coder_DO_As_Impossible•3mo ago

@myzstral Redo the wiring work, neatly and send the updates here. If I am not, then Darwin will surely help

myzstralOP•3mo ago

it probably has no wiring issues other than some wires going on top of eachother and hiding the ones underneath i tried to make it as clean as possible. i dont even know how to make it cleaner anymore tho i will try

Coder_DO_As_Impossible•3mo ago

Send each and every update so that you are supervised and all of us will get to know the output.

myzstralOP•3mo ago

okay

Coder_DO_As_Impossible•3mo ago

Both are almost similar

myzstralOP•3mo ago

this is what i mean by overlaid wires

myzstralOP•3mo ago

at first you're like... "yep thats defo a single gray wire" then you pull it up and go "it was 2... wires?" then you pull it up once more and go "3 WIRES!?"

Coder_DO_As_Impossible•3mo ago

Well, I wont be available for 2hrs straight from now, if I can then I'll keep checking. Either Darwin or nis will help. So Good Luck with it.

myzstralOP•3mo ago

not sure if i'll be on for 2 hours ben here for a few hours already eh

DarwinWasWrong•3mo ago

@myzstral why - really why - do you have a resistor on the 5v rail from the ardiono

myzstralOP•3mo ago

basically it was burning the ICs at one point

DarwinWasWrong•3mo ago

take it off...

myzstralOP•3mo ago

and tinkercad was showing "ICs need 833mV" then i calculated a resistance to drop 5v to 833mV and it stopped for a while sure that resistor was the culprit wow amazing. a single resistor making me suffer for hours. thanks darwin

DarwinWasWrong•3mo ago

When you are running and it show the blown up thing - hover over it It tells you what is causing it

myzstralOP•3mo ago

i did hover it yes at one point it said the ICs were overloaded

DarwinWasWrong•3mo ago

And it said 5v is over the 2.33 VCC

myzstralOP•3mo ago

( prolly an input ) but i messed it up and changed the input to the chip it did fix it not for long tho it says diff stuff at diff times lol

DarwinWasWrong•3mo ago

You are also overloading the arduino pins I read the message.

DarwinWasWrong•3mo ago

Which is where one ponders - why is VCC 2.42 V The next step is the inclusion of resistors on the common pins of the display

DarwinWasWrong•3mo ago

The rest of the rats nest - I am unsure of Well the code aint much

myzstralOP•3mo ago

uh i updated my circuit a bit did this and also i updated the code a bit to send all 8 binary values to see if the segments work properly in all digits

myzstralOP•3mo ago

i'll do that it didnt light the segments up

DarwinWasWrong•3mo ago

It is just the pin mode - it wold not affect any other code IS this an exercise ? like test or something - I am unsure why you are not just using a controller chip

myzstralOP•3mo ago

sorry my internet crashed while i was explaining so i put leds to test my binary output code it did work but the segments arent lighting up well i like understanding how things work and doing them myself :P
