hope you all having nice time.
I'm making a joystick controlled 4WD car(4 motors) using AVR and L298m module. when I power the L298m module with 12 v it works perfectly. but i tried to use 9v battery, it didn't work. the module red LED gets weaker when i'm trying to move the car and no motor rotates (the motor just ticks for once). and I already saw projects using two 18650Li-ion batteries which equal 7.4v.
what I missed? and is the battery type matters in such projects?
