This one indeed sounds like the video you would make after spending an afternoon troubleshooting a project...

[@carlost856]

I spend a lot of time on this on one of my first projects.

[@Gameplayer55055]

One time i was raging very badly, so i just soldered a thing directly (temporarily) Flashing raw esp8266 via uart to be exact

[@safiqsheikh4774]

I was looking for something exactly like this and it was on the front page

[@rjs076]

I’ve made the mistake of forgetting to bridge and spending 30 minutes troubleshooting before noticing

[@ImaginationToForm]

Not all though. I've had breadboards with broken paint lines and still had power down the whole rail. I forget who it was but they suggested to test all new breadboards so I do.

[@spidermancereal]

same here

[@paulfrost8952]

I think I better check my breadboard for that. Sounds like best practice.

[@elnino530]

Yooooo, that explains why my current almost never worked when I used those, and no one saw it necessary to put that little detail on the box the board came in 😭

[@JM_Tushe]

I learned this the hard way at University. 😂 I wouldn't change it, it got us a good laugh.

[@Zwettekop]

More important question: Why do breadboards with continuous red and blue lines still have a gap in the power line holes? So often I need to move my entire project by one hole because it doesn't line up properly. (See 0:07 for what I mean)

[@matambale]

not only are there gaps every five holes, the power lines are offset by 1/2 a gap width.

[@StephenErmann]

@@matambale My theory is that is done to visually remind us that these are different from the main section, but this is just a guess...

[@matambale]

@@StephenErmann I think you're right.

[@JosephDavies]

@@StephenErmann That's my (entirely unsupported) assumption, too.

[@Gameplayer55055]

These split rails really helped me when i was building circuits with op amp and +12v -12v

[@NiceEyeballs]

I spent like 2 hours. Then I realised that. I wasn't even mad. I was able to run 3.3V 5V 12V and 9V. Ingenius. But yeah these breadboards could've been better if supplied with those bridges

[@the_real_sublicious]

I actually had this problem while using my new breadboards and I didn’t knew that this was a thing

[@velho6298]

This is the noob pitfall for sure. I am not saying that I ever fell for it but you know...

[@promultigamer1997]

Ive got some cheap breadboards that have the gaps, but arent split...

[@RobindenHertog]

I tend to use staples as short jumpers, anyone else do that?

[@Unoxfan2000]

How do i know how many ohm my resistor has to be?

[@dinnerchief]

i like stereo bipa n bops in music

[@VictorFNV]

Is there a way to electrically bridge the gap? I have an arduino uno and i have an air valve. I need the valve to open and close on a timer. But it needs 5V and when i try using the digital pins to send electricity over. Its not enough. I know it works as i tested LED's on it. But i guess the digital pins give out 3v and not 5v. Any way to make them 5v?

[@jameswise9171]

The example of 12V and 5V is bad because there's already 2 rails I'd've added 3.3V

[@pluggedfinn-bj3hn]

Good thing I got my big breadboard from dad and it had all the gaps already bridged 😅 Probably would've made the mistake at some point otherwise

[@dcf476]

This fact done me in for over an hour one day! For the life of me I could not get the circuit to work, redid the entire circuit again and still nothing! Grabbed the multimeter checked a couple of points......DOH!!

[@two0ort]

cool thing with the different voltages, but cant you just use another power rail by connecting it to the other rail or taking two from a small one and repacing the loong one with the small ones?

[@tauruschorus]

Nice

[@Bapate-rh9be]

I thought all of the 5 hole elements areseparated and implemented jumpers to connect them all together over the entire length of the board befor even trying to use it the first time. I will separate a few of them and check wether there is still contact.

[@scythascytha2849]

Do all breadboards do this? I thought the power rails were all connected..

[@SmithyScotland]

Been there, done that.

[@gtaviper]

Hmm just checked mine as the bottom foam came off so I fixed it with tape and I cam confirm this Is not always true. Or I have a very cheap one xD

[@davidfree007]

Had exactly the same issue the other day! Grrrr

[@azimalif266]

I didn’t know this when I used these for the first time.😂

[@wilurbean]

So you can turn that bus into a big voltage divider

[@tonysicily2687]

What is the rating of the capacitor please?

[@arceusthegod2612]

This one has 104 written on it so it is 0.01uF

[@tonysicily2687]

@@arceusthegod2612 thank you, much appreciated, I will order a few 104’s to help clean up the power.

[@glucosesyrup3427]

Thanks. I am stupid

[@tim_allen_jr]

Food for my brain 🧠

[@james77011]

do u have a longer video on this topic?

[@xanri7673]

Why do you put a capacitor between ground and 5V at 0:03

[@cpu_1292]

Capacitors help reduce noise

[@donniesmidway]

Thank you for this
