Thanks for the reply Jeremy, yes I managed to get the script compiled in the end, I messed up with the adafruit library and used the wrong one! Just waiting for the rest of my LED strips before I can put it all together. Not entirely confident on the wiring of sd module, buttons and rtc but I’m guessing it’s the same as in adafruit tutorials for those modules. I see you have used pins 4/5 for buttons and pin 9 for cs on sd module. Do I need resistors for those or do they use resistors onboard? And do I need specific buttons for this? Sorry for all the questions, relatively new to programming and electronics so apologies if my questions are really simple. Once powered, and with game sketch loaded onto arduino, will the matrix display anything before I push in the loaded sd card. Many thanks for your support, genuinely appreciate it greatly
