hydrv:
Hi,
Currently I am working on a project which has 2 DC motors, 1 Servo, Pololu sensors, Ultrasonic and Sharp IR sensor. Firstly, 2DC motors are supplied by 9V battery and Arduino is also supplied by seperate 9V battery. We have realised that the general use 9V batteries are not enugh and draining quickly. We have purchased rechargable 11.1V 1450 mAh C 25 Li-Po battery and will use this. We want to power both Arduino Mega 2560 and DC motors by this batterry together. Some friends told voltage regulatory circuit is needed.
I have searched online on this but could not find valuable information.
- Do we need voltage regulator for DC batterry really?
Not if the motors are rated at 12vdc. The arduino external power connector does not require a regulated voltage as it is regulated down to +5vdc by an on-board regulator.- Can you suggest links or etc. so that we can built this circuitry?
