    Finding the Right Weight Sensor for a Color-Changing Coaster Prototype

    Thanks, we had the same idea with aiming for the right sensitivity. We'll start by getting a force sensor that covers the proper range of weights.

    Finding the Right Weight Sensor for a Color-Changing Coaster Prototype

    We have made sure the weight is evenly distributed by placing a square piece of foam on top of the sensor. But I'm really not sure what's causing the problem with step time - our circuit is set up exactly like the one shown here: http://bildr.org/2012/11/force-sensitive-resistor-arduino/ We've...

    Finding the Right Weight Sensor for a Color-Changing Coaster Prototype

    Hi Don, thanks for your response! The FSR we got actually ended up having too low a weight range to be able to handle a full glass of water (output voltage would max out at medium-high weights), but we are having problems beyond that. We practiced using it with smaller weights (some small gears...

    Finding the Right Weight Sensor for a Color-Changing Coaster Prototype

    Hi all, I'm new to the forum so I hope I'm posting this in the right place. I'm currently working on a senior design project which requires my team to create a working prototype of a coaster that changes color based on how full the drink on top of it is. We plan to control the prototype with...
