    Just started a massive IOT company without a programmer salary in the budget. I do hope watching a couple more of videos with Julian working like this, I'll manage to take this on programing role. 😉 Thanks mate. (Sorry, all BS💩BTW) I really do like his style.

    the adafruit oled library is much easier to use

    Current project is using a b-280 pressure sensor and a weird little areuino called a pro mini I believe. Its supposed to take in 5v on the "raw" pin, as the two serial pins as inner rather than edge pins, just basically wierd. I'm also going to need to use a serial to TTL converter. Things I haven't done. But, made the mistake of ordering this a while ago, and I want to put it to use. Huge learning curve but might be useful some day.

    Julian, Any particular reason for static char and static float…??

    Watching the Ben Eater breadboard PC videos revolutionised my approach to breadboard wiring.

    Thank u for zooming in to your code, keep it up!

    thanks julian for the code in doing the milisec the adafruit library didn't work i just got square blocks and no numbers so used the U8x8 libraryand it works

    It's a method not a function. Pedantic semantics, but in general a function is passed all the data it needs as parameters. A method uses stuff from the object it resides in. So in this case the .begin() method is using things like the address, port, etc from the object oleg, which aren't passed to it, so it's a method.
    Gets a bit complicated with static methods/functions, but who cares lol

    glad to see you back into arduino

    Hi Julian, why did you choose to use the Si7021 over the BME/BMP280 sensor? Was it because your old project (using the BME/BMP280??) failed to work with the latest Arduino IDE etc?
    Keep up the great videos and cheers from Down Under.

    Isn't this sensor able to measure atmospheric pressure?

    What is the black board in the background? Some sort of small format mega?
