Dual 6 digit led display clock......is there a design somewhere?


hello group.
     i'm in wrong section, heck.   for time now, i've been looking dual display led clock design.   i can't ham wants one.  needs show 1 display using 24 hour format , other using am/pm 12 hour format. need display seconds on both displays.  i'm looking use 6 digit displays @ least .75", 1.00" better. guess time base battery backed rtc board of flavor. doesn't matter arduino used either. function helpful 9.5 minute timer recycles , beeps and/or flashes indicator long switch on.     i don't have wherewithal design , program right because of medical issues, appreciated. know of guys incredible @ design , programming arduino , in debt.

hi ken sorry hear medical issues. i'm sure here wishes speedy recovery. in section of forum love keen learn , willing try hard. not free design , code service. there section of forum called "gigs , collaborations" can offer pay that.

anyways, want sound do-able ordinary arduino. larger displays fine if colour red/yellow/green, large blue or white displays require higher voltage, making design little more complex. couple of max7219 chips seem suitable, or perhaps ht16k33 module. rtc go ds3231 module rather ds1307.

#1 tip: don't buy until have checked suitability you.
