How does a L293 make a stearing wheel turn? :~
I have a feeling that the OP is trying to control some largish gearmotor of dubious specs using an L293 to actuate the steering on a Barbie Powerwheels (or similar) Jeep; given that the OP is using 12 volts, its likely not the smaller 6 volt Jeep, but the larger "full size" one...
If this is the case, then the motor used is likely needing waaaay more than the 1 amp the L293 can provide (if the L293 hasn't had its magic smoke liberated)...
