I apologize if this is already a topic, but I could not find any info while searching the forum.
I am using the the sparkfun Muscle Driver V3 (https://www.sparkfun.com/products/13027)
The tutorial provided shows how to hook up this sensor using two 9V batteries. This works well, however my plan is to embed this sensor into a project using a LiPo battery,charger, servo motor and an arduino nano.
I can't seem to figure out how to supply negative AND positive voltage using a single battery. Is this possible using some type of hardware?
Thanks in advance for any help!
