Recently I've been working on an RC car controlled by a Raspberry pi mounted on an RC car and connected to 2 motors via l298n dual h-bridge and im using a 12V battery to power the l298N However it only outputs between 2v-1v to the motors and that s not enough to move the car. So my question is how to controll the voltage output of This Driver ?

they are talking about other drivers not the one i mentioned. but i can tell that voltage drop is a common problem as i see. and another thing i need to mention i think that the problem has a relation with the Pins Highlited in the image link i posted – 19999999 views Jan 30 '18 at 17:33

1No, the L298 is clearly and unambiguously covered. I wrote it so I should know this! – Andy aka Jan 30 '18 at 17:35

my bad i thought the L298N is diffrent then L298 (without N) but that doesnt solve the problem does that mean there is no way to fix the voltage output ? it s a huge drop from 12V to 2V ... – 19999999 views Jan 30 '18 at 18:48

Motor coils have a DCR value . WHat is it? You can measure with an ohm meter. Yours better be >= 3 Ohms otherwise wrong bridge. What is voltage on both sides of motor coils – Tony Stewart EE75 Jan 30 '18 at 20:05

yess it s higher than 3ohms. i have a 12V battery input to the Driver and it ouputs aroud 2-1v. in the morning i made some digging and i think the problem has to be with PWM signals if increase it maybe the output voltage will be higher ? i wanted to ask before tring because i dont study electronics it s just a hobby – 19999999 views Jan 31 '18 at 10:13
