hello everyone, am starting to venture into the specific topic sections after dabbling mainly in the "General Electronics" and "Programming Questions" ones.
i have an Arduino Uno with a Motor Shield (1A, based on L293B chip); http://www.dfrobot.com/wiki/index.php/Arduino_Motor_Shield_(L293)_(SKU:_DRI0001)
i'm using a pair of old DC motors lying around which are rated at 9V and Max.consumption of 0.65A.
that current setup should be quite safe (workable) to use with a 9V battery to the Uno DC jack, right ?
my question is, the product wiki says; "The Motor shield is powered directly from Arduino." - does that mean that the shield takes the 9V for the motors from the DC jack, or that it takes only 5V which comes through that DC jack.
this is the schematic if it helps at all (for one who can actually read it !) http://www.dfrobot.com/wiki/images/3/31/Arduino_Motor_SCH.png
if it's not the 9V that is taken, what i understand is that connecting to the L293 chip directly, one can connect the external power supply to the Vin pin for that chip - how would one do that with the shield ?
