Conducting Foam Controlled Servo's





Introduction: Conducting Foam Controlled Servo's

This video shows the use of conducting foam as an input for the Arduino Duemilanove. The output consists of 2 servo's which, eventually, will control a robotic hand.
The conducting foam was taken from a pcb-case (originally to prevent static build up).
The Arduino scetch is found in extended->servo->knob and doubled (or tripled etc.) for control of more than 1 servo.

    Thanks very much for the code, I'll try it later, no time this week. Anyway I'll let you know how it works !

    nice idea , but u might wanna smooth out the shakiness in the servos
    witch can easily be done with an if statement and some math .
    lemme know if u want to know the code , even though idk if it is arduino compatable ( c++ code like)

    I'm an electronics man myself so any code to improve the electronics is welcome !

    heres an example for a single servo and input

    i did a little research on how arduino works  so it may actualy work right away , but its compleatly untested

    #include <Servo.h>

    Servo myservo;

    void setup() 
      myservo.write(90);  // set servo to mid-point
    void loop() {

    int calibrate = [ a number to mess around with ]
    int an0 = map(analogRead(0) , 0,1025 ,0,180)

    If (an0 => (an0 + calibrate )  )
       myservo.write(an0 )
    else if ( an0 =< (an0 - calibrate ) )
       myservo.write(an0 )


    what this does is checks to see if the the analog pin ( after being mapped to work with a servo ) is within [calibrate] range . if its not in that area , it will change the servo's position ... i hope

    lemme know if it works =D

    >< just noticed

    add a semi colon to the end of every statement except the if , and else if

    example :

    void loop() { <--- not here

    int calibrate = 5 ; <---- here

    If (an0 => (an0 + calibrate ) ) <--- not here
    myservo.write(an0 ) ; <--- here too

    !!!! Coincidence : I see you're in Norway, so am I at the moment (well out on the North Sea that is...).

    kools, im in the north XD
