So I am pretty new to arduino and have spent no more than about 2 weeks working with it, I have a basic understanding on the components, with that being said I am trying out relays but can not find a data sheet for a TIANBO HJR-4102E-L-05V relay does anyone know where i can find one, and sorry if this is not in the right section.
