LED Slider Indicator

I don't know very much when it comes to electronics. All I know is how to make a simple circuit. Conect bulb to battery, battery to swich, swich to bulb. I need some help making a circuit bord with an on off swich, 5 LED's & a sliding potentiometer. What I like this curuit to do is, turn on swich, the first led lights up. I push the slide potentiometer up or down & the four other LED's light up or down with the slider.

It sounds like this is what you want to do. so look at the TL490C will do what you want.

This simple circuit should work.

The colours are as follows:

Yellow/Gold = Negative Wiring.

Blue = Positive wiring.

Pink = Wires cross here and I couldn't think of another colour.

Red = Red LED.

Green = Green LED.

Black = Sliding switch.

Grey = Case outline.

Hope this helps!

I don't think this will work. I've played around with a potentiometer connected to a motor & it wasn't a smooth speed up or down. I had to turn it all the way to turn it on, then mess the dial gently as the speed was all over the place. On off, fast slow, nothing accurate. I don't want to fade in & out all the LED's a once. I'm looking for a turn on or off one light at a time as I slide up & down.

Yeah, I get what you want but I have never messed around with electronics so I wouldn't know what works 100% and what doesn't.

Hope you get it sorted though!

Without going the microcontroller method of using an arduino or attiny, etc, you might want to look into some battery level indicator circuits that use one chip or transistors to check the voltage the potentiometer is allowing through and light up the corresponding LEDs. Good luck.
