Many thanks for the help, and where do EEPROMS go to die?

hi, posted thread noob few months project, , given great advice nano job required. , has. i've small 5 axis mill/engraver @ home, have cut casings , pcb'c (should called mcb's (machined not printed lol))


above 2 devices (left) bme280 housing (below left) , main pcb/mcb's. nano goes on larger board after resistors, jumpers (gnd & sda) , rgb led , oled headers soldered. solder nano , place on top board 3 buttons , 20mm speaker


medical grade nylon uncoloured, , led's great in it, red nano's power light!!! did put black enamel on 1 take out. boy likes i'robot lol. green rgb led on it's lowest pwm power setting, bmp goes 0 target glows brighter, turns blue @ correct pressure. red on pressure. lump of plastic parts sat on billet cast nylon.

pins used are...

3,6,9 pwm led
a1 speaker
2,7,11 buttons
a4,a5 i2c oled , bme280
5v buttons
3.3v bme280
both gnds used , connected via top board.

the sketch 2 types of lung physio (button/menu selected), , allows setting changes stored on eeprom settings. know eeprom 'lifed' i'm staying away writes , using put , update instead. i'm using 15 eeprom addresses (i think nano has 1024 dont know sure???) include eeprom register shift user settings addresses if 1 fails? eeproms fail in same way? go high heaven or low hell? can tell? spose bit of code write/read, did written return tell!

anyway, many advice date, i'm off buy mega next project
