I need some help for my senior design project. The general idea of the design is I am using the Arduino UNO combined with the VRbot voice recognition module to control two linear servos/actuators.
Firgelli L12 -R Linear Servos:http://store.firgelli.com/l12-r-linear-ser12.html
I used an H-bridge IC L293D and followed the tutorial here to forward and reverse the actuators:http://luckylarry.co.uk/arduino-projects/control-a-dc-motor-with-arduino-and-l293d-chip/
I have everything working correctly but I need some help on making it portable. I'm using a 7.4V 2200mAh rechargeable lithium ion battery to power everything found below:
Li-Ion 18650 7.4V 2200 mAh Rechargeable Battery module with PCB:http://www.all-battery.com/li-ion1865074v2200mahrechargeablebatterymodulewithpcb.aspx
How can I safely and correctly power both the servos and Arduino board using just one battery. Can I connect the battery directly to both the servos and Vin of the Arduino? Any help would be great!
