Hi..I have created a clock with thermometer with arduino mega 2560 and this led matrix https://www.adafruit.com/product/2276
..temp is send to home server..i use <Adafruit_GFX.h> and <RGBmatrixPanel.h> library... can you help me if it's possible make a simple code only to switch off/on the panel (by the button) ,but the main program is still running and sending the temp to server..I used before this panel MAX 7219 matrix..to switch on/ff i´ve used a "shutdown(true) or shutdown(false)..Thanks Peter
Boy, have you ever set yourself a difficult problem!
That matrix is seriously complex to operate.
