How would you guys do this?

I’m attempting to make a simple prop for a music video.

I want a very thin LED light strip (30 cm long) to light up when pressure is applied to a force sensing resistor.

How would you guys do this?

You could have a lot of fun with this. It could either be very simple on/off, or possibly vary brightness.

On/off is very simple and can be done with a FET/bipolar transistor switch.

Perhaps give some more information about the requirements and constraints (cost, size, time, skill) of this project?

Yes it only needs to be a simple On/off so I will take a look at these FET/bipolar transistor switches you speak of!

Thanks stevech I will take a look at that board also.

I’d need the size of the pressure switch to be no more than 2cm x 2cm and although my skill level is basically nill, I am willing to learn!Initially I have no cost limitation but ultimately I want to find the cheapest solution as I perfect the device. So, to start with I just need to build one that works and then refine it from there as my understanding grows.

I know this is probably a very simply project for many of you guys so please bare with me and accept my general nativity!

Now it depends on how fancy you want this to be. If you’re just looking to turn it on and off, you wouldn’t need anything as overkill as a microcontroller. Even something like combination of voltage divider, comparator and FET might be more than you need.
