I was given the control board schematic of an old vending machine with motors arranged in a matrix array fashion as shown in the schematic below. I was told to use a UDN 2987 to control the rows and TLE 6225 to control the columns. I have read the datasheets and don't really understand what the function of these two ICs are. If someone can help me with reading and explaining the concept behind these two ICs and how they can be used to control the rows and columns of the motors, I'd be extremely, truly, madly, deeply, grateful! Thanks!
