- It may work, it may not. Just having fun with it, let the trial and mostly error commence!
These are 4 Digit, 14 Segment Alphanumeric display modules based on the HT16K33.
You can grab similar ones from these places:
- shop.pimoroni....
- www.adafruit.c...
- ebay.us/AVhpZq
- coolcomponents...
- Or the wider internet, who knew?!
I am using the Adafruit LED Backpack library but there are lots of other available, or bare code if you have the time - github.com/ada...

I don't have a Patreon or a regular donate thingy, I get by fine. That said, if you are mega rich and fancy buying me a coffee, breadboards or CMOS ICs - paypal.me/Davi...
or if you fancy donating something I would find useful then feel free to check out my Amazon wishlist (No pressure) - www.amazon.co.u...
I put lots of my favourite products and stuff that helps me make video up on this Amazon page - www.amazon.com... It is one of those affiliate things.

Bloody hell.... a David Watts video!!! YES!!!!
Nice to see you back ! ...cheers.
Hahaha, Great bloopers!
Thanks! 😁
I remember this guy!
Good to see you're doing well.
Nice to see you in action again! I think there is a quick fix for the color difference, as that board is designed to run off 5V. Just move the VCC jumper to the 5V output of the module. Make sure the VI2C line is still connected to 3.3V though, your suspicion was right - it does set the IO line voltage.
I tried it on 5v, I think they are just different displays.
Yeah, that is the problem with chinesium products. You never know what you actually get.
I bought 5 of those displays on EBay. The LED segments were a greenish blue. You could actually use just one HT16K33 to drive all 8 alphanumeric characters if you have spare 14-segment LEDs, and thus the ESP32 only needs to talk to one I2C address
teach me please
Thanks David. Nice to see you. I like the display, too bad about the mixed colours. Take care.
Woo! He's back! Hope things are going well Mr Dave!
Yay David Watts is back 👍🏻
Don't have a clue what the content is about, but I like this man!
Please... use search/replace for things like that ;) I might be a freak that uses a regular expression to change 2 characters on a single line but this certainly would benefit from search/replace
14 segments displays are quite neat, you just can't display a lot of offensive words on only 7 segments :P
-really wondering why they use 2x2 segments and one half is a different colour :(- I think they forgot to sort the panels and the assembled boards with mixed colours got sold cheaper on Ali
Welcome back.
Breadboard with 6 pin columns exists? Oh well, one more item added to the never ending shopping list....
They are pretty great www.rapidonline.com/k-h-ad-100-advanced-solderless-breadboard-360-tie-points-34-0666
I got one of these from eBay and I was also surprised that two digits were red and two were orange! There must be a story behind this, do you think they are a manufacturing mistake?
He's back! 😀
welcome back !
Who manufactured that wide protoboard with the faint writing on it? Thanks
Those two displays have quite a brightness difference between the two digits..
IRL they a closer but the orange is a little brighter.
Damn $15 for a 4 char display
Your little time is funny ... to hear
I widh I could be like him.
A david Watts video what ever next:-)
