Hi guys, im currently building robotic arm with dc motor control, i dont need it to be servo because its just an assignment. is it ok if directly plug in dc motor to pic and run it.
or use a H-bridge driver. Why dc motor needs a driver? other than H-bridge driver, what are other types of drivers that could be used?
So far i found out L297D is mostly used as H-bridge driver.

Hi guys, i have fixed the entire robotic arm with DC motor and L293B H bridge driver and its working very very well. its fantastic. but the problem is, i need use a power supply, power supply in sense those huge power regulators which you can adjust the voltage you need, because if i use normal power cord which supplies 9V and i pull it down to 5V via voltage regulator, the current is not enough to run the robotic arm, then i used 9V battery and yet its not enough.
the whole robotic arm only functions if i supply them with huge power supplies. the dc motor im using doesnt have a datasheet and i simply supply them with 5V across H-bridge. its those small DC motor for those toy cars. i dont really get the problem
