Latest attempt below. The RTC has been set when deployed via rtc.adjust(DateTime(2020, 8, 12, 16, 32, 0)); in the setup & the serial monitor correctly returns the time. However, the two tactile buttons do not alter the time.
Once I have this sorted the next hurdle will be to alter which LED's fire based on the time.
Any comments/advise would be greatly receieved.
Thank you.
