permission to ask. i have a problem in the project, when i upload my code to arduino uno it turns out that my code requires a larger memory. is there a trick so that it can increase its memory capacity?, if i connect with an SD card can it be?
Code can only be stored in the Uno's flash memory, which cannot be expanded.
Post your code. Perhaps the forum can suggest ways to shrink it.
Please read the forum guide in the sticky post before posting your code.
Please post the memory statistics that the IDE gives you after a compile.
You can not increase the program memory of an Uno and you can not execute code from external memory. You also can not increase the RAM but you can store variables elsewhere, read them back, modify them and write them.
If you are out of RAM, SD will not help as it uses a buffer of 512 bytes so you probably will make matters worse.
If you are out of RAM and you have not made use of the F() macro for fixed text, start by using the F() macro. E.g. replace Serial.println("Hello world") by Serial.println(F("Hello world")); do this for all fixed text.
You will get the best advice if you post your sketch; please do not forget to use code tags as described in How to get the best out of this forum.
