right so let me explain

im a beginner who ONLY and i want to emphasize that ONLY knows python
AND the VERY basics. im trying to make a lil project with a friend and ive been using chatgpt (and for context just in case im 11) and ive been trying to find methods to use micropython (i have experince with it from the BBC micro:bit)
but i cant find ANY so i would love for any assistance.

ive been scouring this forum (through google search so maybe my fault)
but i genuinely dont think any of the methods work (real pythons article dosent exactly fully work).
you can go as technical as you like and even put code snippets, i can understand (i assure you. (please) and i can understand why the "im 11" thing can off-put people but lets be honest, its not exactly great using a junior account. so please help. id love for answers (just to be clear, im using the uno which you get in those lil electronic kits (the cheap ones) so.)
yeah

also i would love for a good png to bitmap converter, the ones above are pretty trashy (most of the code is pulled from chatgpt, and also because i get slaughtered on this forum, i made A LOT. of the code)

to the question

How do i use micropython/python with a UNO

The answer is you don't.

There is just not enough RAM / flash storage on a UNO

see https://docs.arduino.cc/micropython/

Firmware

Arduino has developed MicroPython support for the boards listed below.
ARDUINO GIGA
ARDUINO NANO 33 BLE SENSE
ARDUINO NANO ESP32
ARDUINO NANO RP2040 CONNECT
ARDUINO NICLA VISION
ARDUINO PORTENTA C33
ARDUINO PORTENTA H7
ARDUINO PRIMO

11 is a good age to start learning C++...

rq the flash storage is the microprocessor right,
if it is, can we not upgrade it?

(also yeah i plan to start c++ but i started with python so might asw finish it :))

nope - it depends on the ATMEGA processor you have ➜ 4/8/16/32K Bytes of In-System Self-Programmable Flash progam memory for ATmega48P/88P/168P/328P

the UNO has a 328P so 32K

if you want to play with python on a small MCU, get a RPi

got it. thank you!
