I can't help you with all your questions, but I can explain the difference between rgba bgra. I don't exactly know why they use different types, but both of them represent a color. RGBA stands for red, green, blue and alpha. Where as in BGRA only the order got switched. Here we have blue, green, red and alpha.
For the color "FFFF00FF" that would mean:
RGBA:
Red: FF
Green: FF
Blue: 00
Alpha: FF
->yellow
BGRA:
Blue: FF
Green: FF
Red: 00
Alpha: FF
->cyan
So the difference between RGBA and BGRA is just the order the bytes are stored in.

@AbsShek I used the method @moars42 described. And for the lower module I modified the picture a bit to increase the contrast and the I could see most of the part number that combined with a bit of background knowledge lead to my conclusion.

@kurtr I edited the picture a bit so I can read the writing on the lower module and this one can be found by googling the datasheet for the "A3144" also a hall sensor but for operation in high temperature environments.

@kurtr The first one is a linear hall effect sensor. You can find the datasheet if you google for "SS49E". The second one I can't properly identify because I can't read what's written on it in this picture.

@DjSall @Krokoklemme no the return ends the function. After a nice child the function ends with the return and skip the naughty part.

@Codex404 No here in Germany we have qwertz

Because of the distance between y and z on the German keyboard layout definitely [ CTRL + SHIFT + Z ]

@SirWindfield ok I haven't thought about that. There you may be right.

Thats not a bug. It's a feature. So you can reply to multiple people without having to type their name.

@ScribeOfGoD no I don't have a problem that he wrote a rant about reposting. But I think everyone can write, especially here, what he wants and even repost. I just don't like it when people just try to find mistakes made by others.

That's not very nice. Is it that big of a problem for you if two people have written the same or posted the same picture. Just let them do what they want.

I also have to use BlueJ at school. I don't like it but especially for beginners it's way easier to understand the structure of the Programm by looking at every object with the inspect Funktion than to you own debugging code.

Our computers at school don't allow us to switch to the dark theme.😒😒 But at home always dark

But I always hate it when I don't scroll perfectly straight and it switches tabs.

Mobile:
Looks great, but I wouldn't use the changing color as default. That's a little bit distracting. And after you have written something in a text box and close the keyboard, the site scrolls up so you can't see what you have written. As already the 'What we have done in the past' section looks great, but I think it doesn't really fit in there.

That's right but it's way more efficient to change a tire with airtools than by hand. Both do the same job but with the right tool you are way faster.

Maybe with a batch file?

@aram but actually they created a lot more problems than they solved.
