Hello, this is my first time to post here. I really need some help. How can I drive servos and DC tamiya motor at the same time?
Is there any products in here that would fit to my needs? I am building a Table Tennis Trainer(bot) for my final project in my course. :)

Who don need help and post here? :lol: Besides the few active members that always contribute.

You can try Arduino with Motor shield, just add in Servo library to control sensor while motor shield can drive the tamiya motor.

Uhmmm, it has been arranged that we do it in PIC, so i really need some help, a little help is helpfull enough. So please, suggest a product here that would fit my needs in driving both the tamiya motor and the servo at the same time without adding too much capacitors? :D

your motor need to rotate 2 way? CW and CCW?
u can control your servo with PIC. u are using RC servo?

No, Im just using plain servo coupled with a DC motor. The sevo acts as an arm that would push the ball to feed to the ball. Now, My problem is my project requires 3 launchers with an XY rotation. So, its gonna be at least 9 servos and at least 3 DC motors. My problem is how can I control them. :D.. Is there any product here that would fit or support such requirements? Plss. Help me.

im controlling at least 9 servos, my motor could draw at at max 5A(a Tamiya Dash Motor), and lastly what should be my power supply?

If you have money, get switching power supply with the correct voltage and current rating, else you can use lipo or SLA and design a high current voltage regulator.
