sir/ma'am i want to do "Seven segment based digital clock with time set option using 8051 microcontroller (AT89C51)" project. But instant 5v SSD i want to use 12v SSD ( BIG ONE) so how i can connect to the circuit. please help me.
First find the current capacity of 12V seven segment and according to that use driver IC (i.e., L293D or ULN2003). Output of Microcontroller connect with input of driver IC and output of driver IC connect with seven segment display.
