FSR to unlock

Projects General Guidance
1

I apologize if this has been posted before but I have looked everywhere I know to and can't find anything specific. I am new to the system and specifically I would like to use an FSR that when an item within a particular weight range is placed on it, it triggers an output. I haven't tried writing the code yet because I was hoping there was already a sketch out there that is close.

Does anyone know of or have a sketch that simply checks the range and delivers 1/0? Thanks in advance for your help.

I haven't tried writing the code yet because I was hoping there was already a sketch out there that is close.

How difficult do you imagine it will be?

   int analogVal = analogRead(analogPin);
   if(analogVal >= lowerLimit && analogVal <= upperLimit)
   {
      // By jove, the weight is within range
   }

Wow. I guess I had assumed it would be more difficult for some reason. I really appreciate the help.
