We do quite a lot of LED work however ive never used arduino. Ive got a raspberry pi and a load of different sensors sat in a big box at home but havent had chance to have a play around.
I want to build a small project where i have 4 weight sensing pads. As weight is applied to each pad a corresponding strip of pixels will chsnge colour.
I.e. pad 1 10grams is red 20grams is blue 30grams is green.
Pad 2 is the same
Pad 3 is the same etc.
Cpuld anyone point me in ghe right direction of what equipment i need to buy (recommend weight sensors?) And possibly point me in the right direction?

Any help is much appreciated.
I would start by just using three RGB LEDs and think anbout strips later.
Regarding sensors you need to know the maximum weight they need to measure, the resolution required and the physical characteristics of the weights so that you know they can fit on the sensors. Then use a search engine.
Okay, had a quick google before poating but couldnt find much info on the sensors. I've got an absolute wealth of ws and sk strip and some individual pixels.
I think ive got a lux sensor at home so i will dig out the raspberry pi and try to find a tutorial on controlling a pixel in relation to lux.
If anybody else has any tips or info it would be much appreciated!
Are these weights meant to be accurate and repeatable over long time periods?
A force-sensitive resistor is not accurate or repeatable but it can probably work well enough to detect the examples you gave.
If it is more like a scale in a laboratory then you need to start from a digital scale sensor. There should be many Arduino examples online for scales.
Im just building a sensory toy for my daughter. I want her to be able to pile 10 toy bricks in a basket. And as each brick goes in the light changes colour.
