I am using a Uno for a little project, but i have run out of dynamic memory, i have tried moving my array using PROGMEM however it doesn't seem to have moved my array as it still says
Build options changed, rebuilding all
Sketch uses 6,466 bytes (20%) of program storage space. Maximum is 32,256 bytes.
Global variables use 2,745 bytes (134%) of dynamic memory, leaving -697 bytes for local variables. Maximum is 2,048 bytes.
i would be grateful if someone could tell me how to rework my sketch to make it fit on the Uno.
/*
NOTES
Speed control knob is A0
Intensity knob is A1
Switch is digital pin 2 via a 10k resistor
