i'm trying to connect my arduino to 3 7-segment displays using a max7221 and the ledcontrol library, but now i've ran into a problem.
i want to display an value that comes from the A/D converter ( a number from 0 to 1023) the value isn't going to go any higher than 999.
with ledcontrol you can only send a number from 0 to 9 to a display, so i need to "separate" numbers in individual numbers to send them to each corresponding display. analogRead gives me the number 587 , this has to be separated into the numbers 5 , 8 and 7.
how can i do this?
