hi...

i need to control three servo motors using a 8051.....can i put the control input to the servo directly from the port pins of 8051?? does the control pin of servo draw much more current than that available from 8051? can it damage the micro...??

i guess..all the current required will be drawn from the power supply...right?? control pin just needs proper PWM signal(with proper amplitude) to rotate the motor...right??

in case not....what kind of interface should i use for servo with 8051??

plz help...

Yes you are right. No problems in interfacing the 8051 directly to the servo motors.
