I saw one of these at my makespace (i know your jealous) but forgot to take a irl pic, found it online tho

i think this is good, i might change later tho
This can be pushed forward, back, and pressed down, so its great for selecting stuff

After that i just worked on connecting the display - i followed the tutorial at https://www.instructables.com/Arduino-and-the-SSD1306-OLED-I2C-128x64-Display/,
but the Arduino IDE was being a bish, and the I2C scanner wasn’t working - there were 2 reasons :

  • First, I had the wrong I2C scanning program twice (it wasn’t compatible with ESP32, it was only meant for arduino)
  • Second, there is a tiny difference in some displays - most use 0x3C with SA0 pin pulled low, but some use 0x3D with SA0 pin pulled high, whatever the hell that means.
  • Third, and i saved the best for last, i was giving it 3.3V which should have worked, but again, it was a should. So i switched to +5V VDD, and it started up !

I just wanted to test the display was working, but it turned into a real marathon.

Anyway, i wasn’t sure if i had space for Hello World, so heres just a hello :

Also, im realizing now, i definetely have space for that, since there are two rows for text. lmao.

Anyway, im signing off today, and i’ll be back tmrw, because first its late now, and also i forgot to take the lil switch with me, so tomorrow i gotta go pick
it up from xHain (my makespace even has a cool name :P)
