language reference-memsic servo

Projects Programming
1

I have a Memsic accelerometer hooked up to my Uno which controls the movement of 1 servo. Thats working pretty good. What I would like to know is the following: I want to be able to use three push buttons. For each button I want it to use different paramters. For instance one push button would use an if/else to move the servo. The second pushbutton would just move the servo to a certain position and the third would do whatever. So whatever button I use would trump the rest and the program would only follow whats in that specific buttons code.

What is the setup/or structure called so I can do this? or if you know of an example that has already been dont that would be great.

and the third would do whatever

Specification. Yeah!
You need to post the code you already have.

Will do tonight when I get home from work.

In the mean time can you tell me the name of the statement that could possibly work for this?

No, there is no single "statement" - we need to see how you have your buttons set up.

Thats the problem. I dont have a button setup. I was hopping i could get an idea from here, add it to my code,and then if it didnt work post it.

Tonight when i get home i will attempt it again and then post it

Thanks

Below is the code I have to control a servo with a memsic 2125. The code works fine as is.

What I want is two buttons which causes the servo to work differently depending on the button pressed.

So for example if I pressed button 1 it would read the if else assigned to button 1 and if I pressed button 2 it would read another if else.

How would I go about doing this? What statement would I use?

#include <Servo.h> 
 
const int xPin = 2;   // X output of the accelerometer

const int yPin = 3;   // Y output of the accelerometer
 
Servo myservo;

int val;
void setup() {

  Serial.begin(9600);

  pinMode(xPin, INPUT);

  pinMode(yPin, INPUT);

  myservo.attach(9);

}
 
void loop() {
 
  int pulseX, pulseY;

  int accelerationX, accelerationY;
  
  pulseX = pulseIn(xPin,HIGH);  
 
  pulseY = pulseIn(yPin,HIGH);
  
  accelerationX = ((pulseX / 10) - 500) * 8;
  accelerationY = ((pulseY / 10) - 500) * 8;
 
 val = (accelerationX);
 
val = map(val, 0,1000,0,90);


if (accelerationX >0)
{
  myservo.write(val);
}
else
{
  myservo.write(-val);
}

  Serial.print(accelerationX);

  Serial.print("\t");

  Serial.print(accelerationY);

  Serial.println();

  delay(100);
}

So for example if I pressed button 1 it would read the if else assigned to button 1

I don't understand what you mean by this - you don't "read" an if/else, you execute one or the other.

Thanks for the correction. So all I want is when I press a momentary push button for one command to continuously loop until I press another button.
