### FSR - Conductive foam readings

Hello! I am making a prototype of a force sensitive resistor, and i am using, to old 97%kobber coins, metal sheet and a tiny piece of conductive foam that i got from a tv-repair shop. The setup is not very good, but its a start, and i am planning the next move for better results... Now... I want some decent understanding of how the readings work, and why I get these results.. First test, are written with black, and and as you can see it, has the same amount of space between 0-1kg and 1-2kg, but 2-3 and 3-4 changes to a very small space? Why is that? Second question is, that i have used the x10, to read larger forces. 0-2,5kg and 2,5-5kg has same amount of space. Will the space decrease too, when getting further up the scale too?  - I know the conductive foam has its limits too, but just to be clear of my readings. Thanks in advance! I hope you can see the readings on the picture..!

### Force sensitive resistor plus LED plus battery. Will pressure on the FSR be able fade the LED brightness in and out?

I am trying to achieve a handheld firefly effect by using an LED that is controlled by the FSR in order to get the "firefly" light to fade in and out. Can someone give me an idea of how to set this up? Thanks!

### how do you measure the weight of pushing on every pedal of a bicycle?

It's for a school project.. I thought the FSR sensor and arduino. I would like to measure the weight of a person for example 100kg.Maximum value of the FSR sensor is 10kg. I would like something more in detail if you could help me.

### Does anyone know how i can connect a FSR force sensor to a digital alarm clock ?

I would like to trigger the alarm when it is under 80 ohm (Maybe).  about the FSR force sensor -- > http://www.ladyada.net/learn/sensors/fsr.html

### Arduino Game Coding - FSR (Pressure Sensor) Based Shooting Game

I'm making a shooting style arcade game in which you shoot a projectile at four different force sensitive resistors trying to rack up as many points as possible before the timer runs out. When a ball hits one of the fsr I want to have the arduino keep score and show it on a 16x2 lcd. Each one of the fsr have a different point value.              Ex:  A ball hits fsr _1 giving the player 5pts, another hits fsr_3 giving the player another 15pts. The 60 second timer then runs out and  the game shows you your score on the lcd... 20pts. I've been trying to wrap my head around how to code something like this but I am just making myself more confused. Any help would be appreciated! Thanks!

### Anyone Have experience with Adafruit Square FSR?

I am hoping to create a circuit that will variably control the speed of a motor through pressure. If I were to wire up one of these http://www.adafruit.com/products/1075 , simply as the switch between a small motor and a power source around 5v, would it work to simply turn the motor off at rest and vary the speed with pressure? Is there a way to use this resistor as a "switch" without using an Arduino or  other micro controller? Any help is appreciated. Thanks!

### Is there a way to change the value of a variable and keep it afterwards? Arduino Answered

Hello everyone, I don't really know if this is possible, I am using processing, arduino and a force sensitive resistor to control a servo and I want to change the value of a variable and then if I reset the arduino, it will kept the new value. Is there anyway to do this? This is the part of my code I want to change. void fsrMovement(){         int maxforce= 1023;  // THIS IS THE VARIABLE         if(Serial.available()){  // SERIAL AVAILABLE TO USE WITH PROCESSING         maxforce = Serial.read();         }         force = analogRead(FSR);  // Reads the FSR               Serial.print("Force sensor reading = ");         Serial.println(force); // This will print the raw force value         int pos = map(force, 0, maxforce, 0, 175); // Scales the force reading to degrees for servo control         Serial.print("servomotor degrees = ");         Serial.println(pos); // This will print the adjusted servo reading (an angle)         myservo1.write(pos); // Write the new angle to the servo         delay(10); // Delay 10 milliseconds before taking another reading

### Reporting plagarism: Arduino Hydroponics

Hello, It has recently come to my attention that an instructable here was blatently plagiarized from one of my previous projects, and in fact actually won an award. The instructable in question is: https://www.instructables.com/id/Hyduino-Automated-Hydroponics-with-an-Arduino/ Proof that it ripped off my project can be found here; my original forum post here goes back to 2012, the instructable in question here was posted November 2014: http://forum.arduino.cc/index.php?topic=130344.180  My repository containing my code on github: https://github.com/BillieBricks/Billie-s-Hydroponic-Controller/blob/master/HydroponicControllerV1.1.0 The code from the instructable in question: https://www.instructables.com/files/orig/FSR/83MH/I2G1F678/FSR83MHI2G1F678.ino The code is mine, line for line, with the exception that the plagiarizing author in question removed my comment at the top with my name as the author. I tried to contact the author, but my messages went ignored and the comments on his instructable page were flagged and deleted.  The author in his instructable says "Big thanks to BillieBricks for working out a lot of the code," but in fact the entirety of the code is simply ripped straight off from my project, along with the ideas and implimentation. My desired outcome would be to either see this instructable removed, or to have the author include that the entire project be credited to me, rather than stealing credit for something they didn't do.  Thank you, Billie
