Mind the Breadboard Gap - Collin’s Lab Notes

2 роки тому

The split power rail is an easily overlooked feature/nuisance of many solderless breadboards. #adafruit #collinslabnotes

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

@carlost856 2 роки тому

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

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

@rjs076 2 роки тому

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

@elnino530 5 місяців тому

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 😭

@Gameplayer55055 4 місяці тому

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

@JM_Tushe 3 місяці тому

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

@ImaginationToForm 2 роки тому

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 8 місяців тому

same here

@paulfrost8952 4 місяці тому

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

@the_real_sublicious 2 роки тому

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

@davidfree007 2 місяці тому

Had exactly the same issue the other day! Grrrr

@jameswise9171 4 місяці тому

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

@Zwettekop 2 роки тому

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 2 роки тому

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

@StephenErmann 2 роки тому

@@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...

@dcf476 2 роки тому

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!!

@NiceEyeballs 3 місяці тому

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

@two0ort 4 місяці тому

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?

@azimalif266 3 місяці тому

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

@donniesmidway 8 місяців тому

Thank you for this

@Bapate-rh9be 4 місяці тому

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.

@pluggedfinn-bj3hn 4 місяці тому

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

@SmithyScotland 2 роки тому

Been there, done that.

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

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

@RobindenHertog 5 місяців тому

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

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

@wilurbean 2 роки тому

So you can turn that bus into a big voltage divider

@PrestonGarveyF4 6 місяців тому

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?
