i need some help .
I made this montage but instead of TIP120 i used tip121 and instead of 1n4004 i used 1n4007.
With the diode i think is not a problem
The problem is that that the motor powers everytime i connect the battery.
I want to stay stood at first and depending on the program to start rotate . (pin from arduino in As OUTPUT).
I thought the resistor was supposed to keep the motor stopped at first .
My main concern is : i should change the TIP121 with 120 , and then all will work just fine ?
I haven't found any TIP120 transistor that's why i used this one .
P.S. : the battery is a 9V one
