i'm using atmega 8 for creating a pwm for a 12v motor
the pwm goes to input of a l298n and the corresponding output goes to motor
atmega works with a 5v,and i use a 7805 which its input is 12v
for the logic supply of l298n i use the same with atmega
and when i use a seperate 12v supply for the ,main supply of l298n everything works fine
but if i use the same 12v which supplys the 7805, it just stops working
i just want to use one power supply for the whole circuit
any help would be appreciated
