Title: motor driver for roboduino
Post by: Adityav95 on September 14, 2011, 02:55:32 AM
I wanted to make use of a old RC car chassis which already has 2 motors. I searched for a motor driver and found a couple of 'em.
1) http://probots.co.in/index.php?main_page=product_info&cPath=54&products_id=361 (http://probots.co.in/index.php?main_page=product_info&cPath=54&products_id=361)
2) http://probots.co.in/index.php?main_page=product_info&cPath=54&products_id=197 (http://probots.co.in/index.php?main_page=product_info&cPath=54&products_id=197)

Some questions: (I'm not the best electronics guy out there so please bear with me!)
1.Is there any thing i should keep in mind for compatibility with roboduino or are all motor drivers compatible?
2.Could you also tell me how to use one and connect it to the roboduino? Like which thing to be connected to which pin in the roboduino etc..

(I guess direction control is more than enough. Speed control is not necessary at least at this moment.)

Thnx a lot.

The roboduino is Arduino compatible so a google search like........

may help you.

It might be good to know the current drawn by your RC car's motors: the faster ones can easily draw 30+A, and that would require a rather hefty motor driver.

Two more questions;
1. Whats the difference.between a serial based motor driver and a one based on 4 digital inputs?
2. how many uart ports does a roboduino have? (the schematic shows 2 but the features page on curious inventor shows only 1 dedicated uart)

Thnx
