How to add memory to arduino
Nettet12. feb. 2024 · You're not adding memory to the Uno there - you're adding an external peripheral that happens to have memory. Adding memory to the Uno would entail including it in the memory map so you can use it for variables, etc - something the AVR doesn't support. Nettet9. mar. 2024 · The microcontroller on the Arduino boards have 512 bytes of EEPROM: memory whose values are kept when the board is turned off (like a tiny hard drive). Functions in the EEPROM class is automatically included with the platform for your board, meaning you do not need to install any external libraries. Hardware Required
