Arduino relay timer code9/12/2023 While timer is active (running or paused) the relay output is switched on. Second press resumes and long press ends the timer. Timer can be paused with a press of switch. Rotary encoder switch used to start the timer Rotary encoder allows setting the required timer value Arduino manages the display as a multiplexed POV refresh using direct I/O Relay output or relay module (commonly available on eBay and other suppliers) Rotary encoder with built in selection switch 7 segment 4 Digit LED display (similar to ) Implementation 2 - Arduino outputs directly runs LED segments State = S_IDLE // in case we get into trouble!
