So helpful 🙄

❤❤❤❤❤❤❤

Hello, are you a seller of Arduino electronic components? I would like to contact you. Do you have the contact information for your company's procurement department? I urgently need to contact you. Thank you very much. I have something to talk to you about

so it is possible to power through vin and use 3.3 for sensor. Thanks alot

Is it a 90 degree turn servo

Hi Koen Verbeeck. Is there any solution for uploading code using Python?

or you could just power it straight to the 3v3 pin with a single one, as everybody who's not a monster would do.

code pls and diagram or at least the code we can identify the pins from the code, but it would have been nice if you could upload the code.

Hi Koen, love the video. I am trying to build a similar mechanism for a can. I’m wondering if you could tell me where I could purchase the hinge. Thanks so much.

bro show the circuit

Im so thakful to have found this, ur awsome

Could u upload the code?

How do I make it louder than this? Can I change teh size of the transistors or resistor? When I hook up my buzzer directly to a 12V power source, it's way louder so I know it's capable of more.

do you have the code? i'm trying to white the code with serial.read and serial.print but it is in auto, or sure, it isnt reading my comand in the COM SERIAL

Sort of a late comment. I have this same issue And accidently discovered there is a capacitor on the back of the board, if touched by your finger, the display will come on and continue working until reset.

Hey I’m working a project maybe u can help me With it

i also ordered three of them via ali express. two of them had the 'skipped every odd lines' problem. if you have this issue: inspect the glas of the oled. the problem occurs when the edges of the glass are bent/broken. i think, it is an design flaw with the display having space between the board and the glass. i secured the working one with hot .glue

Hi pls can you share more details of pinout and sketch? Cheers Stefano

same problem: ordered three from ali express, two of them have 'broken' display (skipping every odd line). just waiting for my refund now.

Leuk geschenk voor kerstmis :) job well done!

what version of irremote library were you using?

I tried this, but it didn't work. any suggestion ??

Hello! Did you manage to solve this issue? I just received my order of 4 boards and one of them has the same issue as yours. On top of that, another has some dead pixels rows probably caused by bad soldering.

geweldige muziek

Wow excellent work sir. Is it possible to get code ?

Nice work sir

hahahaaaaa....ook naar Paul gekeken.......

there is no programmers displaying in the programmer option to select

Test with deffault firmware

Amazing video!!

Awesome content bro :) by the way I'm also making DIY & Arduino projects , please take a look :)

WOW BRO, ITS A GOOD CONTENT :) BY THE WAY I'M ALSO MAKING DIY &ARDUINO PROJECTS , PLEASE TAKE A LOOK :)

Can i use addressable Led and stepper motor both using same arduino nano?

Can i get the code for this project?
