Hello Arduino forums!
I consider myself to have intermediate experience with Ardunio. I have a project that I'm trying to accomplish and would like some guidance:
- I plan to control a simple RC car
(something like this http://www.hobbytron.com/ChubCityLincolnNavigatorElectricRTRRCCar.html#)
I plan to strip the body and add a claw & arm.
The claw will be controlled by two of these (https://www.servocity.com/html/hs-5065mg_servo.html#.VjakMLerS-Z)
The Arm will use a small micro servo that will function as a linear actuator to raise/lower the arm.
The car has 2 small DC motors. I connected a AA battery one of the DC motors on the car and heard the motor move; thus can I conclude that each motor runs on ~3v? (Car has slots for 2 AA batteries)
I plan to use a bluetooth module to control my RC remotely from my bluetooth-enabled laptop (http://www.mouser.com/ProductDetail/Adafruit/1588/?qs=GURawfaeGuCAp6XFsR2m0Q%3D%3D&gclid=CjwKEAjw8NaxBRDhiafR-uvkpywSJAAxcl6fjO0KTFsxCAOSrD6k6F7mCh3SEqykEZfC7YUSzMRlWhoCtKHw_wcB)
I plan to use a 9V battery (maybe 2, scroll down to questions) to power the Arduino
So here are my questions: - Since I'm looking to power 2 relatively weak DC motors, can I skimp out on grabbing the Arduino motor shield and just use a servo shield instead? I'm concerned about power if I have to stack the motor shield and servo shield. I just feel like the motor shield is overkill.
- I've seen so many guides that have DC motors connected directly to the arduino (Or to a breadboard with an RC circuit), and I've also seen so many guides that say you NEED the motor shield if you want to drive a DC motor. Can anyone clear up the ambiguity on this given my context?
Here's a super rough schematic of what I want to have done: https://i.imgur.com/Ea4nn6p.png
Can anyone shed some light on this? Maybe some suggestions/tips?
