Hello all I am new here and new to electronics. I have done basic and I mean very basic wiring. Battery to a mini lamp and toggle switch. I make dioramas and miniatures and want to start using led lighting. I have an ornament from Hallmark that you plug into one of the mini light sockets of a Christmas light string (3.5v). The ornament has movement and light.
I have cut and wired it to run on a battery without the light. I want to add an led. How do I go about calculating for the resistor. My common sense tells me I would have to figure in the amount of voltage the mechanical part is using. Am I right on this? I want to use a 9 volt battery. Thanks in advance for any advice you can give a newbie.
