Hi, I have been trying to power DC motors, via the L293 using an Arduino BT but I seem to be having some power issues. Is it because the BT can't take in more than 5V power? Any help would be really great at this point, I am quite stuck.

4 H-Bridges: L293D chipset provides 0.6A per bridge (1.2A peak) with thermal shutdown protection
It looks like you are limited by the L293 itself and the voltage regulator on the Arduino if I'm not mistaken
So you need to make sure your motors require less than that or provide regulated external power using the 2pin EXT PWR terminal strip on the motor shield itself
In that case you are limited to what your regulated power supply can provide and the capabilities of the L293 chip
