  • Please look over my Arduino code and tell me what's wrong with it!?

    So, I'm using arduino uno r3 and this is the code that seems perfect for me but it's not working.

    #include <Servo.h>

    Servo myservo;

    int swt = 2;

    int psbf = A0;

    int psbb = A1;

    const int threshold = 400;

    int val;

    int f;

    int b;

    void setup()

    {

    myservo.attach(10);

    pinMode(swt, INPUT);

    }

    void loop()

    {

    val = digitalRead(swt);

    if (val == LOW){

    myservo.write(135);

    backwards();

    }

    if (val== HIGH){

    myservo.write(45);

    forward();

    }

    }

    void backwards() {

    b = analogRead(psbb);

    if (b > threshold){

    myservo.write(90);

    }

    }

    void forward() {

    f = analogRead(psbf);

    if (f > threshold){

    myservo.write(90);

    }

    The switch works perfect, but the pushbuttons won't stop the servo. Oh btw, I'm using a continuous rotation servo. Thanks in advance :)

  • How to make a bounceless circuit?

    Hello, I am a beginner on electronics. I'm making a project for school and I just realized that I need a bounceless circuit. I'm using the name"bounceless" because i saw it once at school. Basically, this is just a circuit with a push button, led, and other components that when you push the push button and release it the led will light up and stay lit; and when you push it and release it again it will go off. It will be great if someone could help me out with a schematic circuit that helps me on this. Thanks!
