Hello, first post, new member and very new to circuit design and creation, so please be gentle
I design and build sci-fi inspired ray gun props and would like to incorporate LED details into my designs.
In researching what I would like to incorporate, I have found that a LM3914 driven circuit would achieve the desired effect, but I have no idea how to design the circuit. I have looked at the data sheets, and scoured the forums already, but I don't know enough to figure out how to modify them to fit what I am looking for.
Essentially, I would like there to be a tri-color, 10 LED bar on the side of the ray gun, that would light 0-10 of the LEDS as a potentiometer knob or slider is turned (in bar mode, not dot mode). I would also like to incorporate an on/off switch into the circuit (to help with battery life), and power the whole thing with a 9v battery (fits best into housing/design). In my head it seem like this is possible and probably pretty easy to achieve, but I can't get my mind around the design of it.
Any help or advice would be greatly appreciated.
Thanks in advance. -N.
