Hello
(sg90 , arduino nano, switch)
the idea is a switch with 3 positions to control a servo to 3 set position on wich they stand still and move fast to.
the servo has it's own power
I did try to make a good working code that does work but nothing worked : read a 3-way switch with (on /of /on1 ) to set ,this one don't work
:
#include<Servo.h>
Servo myservo;
int button_1 = 2;
int button_2 = 3;
int val=0;
void setup() {
pinMode(button_1, INPUT);
pinMode(button_2, INPUT);
myservo.attach(9);
}
void loop()
{
val = digitalRead(button_1);
if (val == HIGH)
{
myservo.write(60);
}
val = digitalRead(button_2);
if (val == HIGH)
{
myservo.write(100);
}
}
and this one don't work :
Servo myservo;
int button_1 = 2;
int button_2 = 3;
int buttonstate1 = 0;
int buttonstate2 = 0;
void setup() {
pinMode(button_1, INPUT);
pinMode(button_2, INPUT);
myservo.attach(9);
}
void loop(){
digitalRead(button_1);
if (buttonstate1 == HIGH);
{
myservo.write(60);
}
if (buttonstate2 == HIGH);
{
myservo.write(80);
}
}
I have build this with a normal switch for on/off read write servo and it works good for 2 positions. the servo act strange like its burning the motor etc. and does not respond to the button1 and little to button 2 but continuously makes noise and moves.
can some one explain why (and i do not always use resistors but i have them all sort, i don't experience the benefit (some experiment? and in digitalread the arduino don't need a resistor ''digital'')
the code that works good, of the on/off switch 2 way servo
#include <Servo.h>
int button1 = 4; //button pin, connect to ground to move servo
int press1 = 0;
Servo servo1;
void setup()
{
pinMode(button1, INPUT);
servo1.attach(7);
digitalWrite(4, HIGH); //enable pullups to make pin high
}
void loop()
{
press1 = digitalRead(button1);
if (press1 == LOW)
{
servo1.write(155);
}
else {
servo1.write(60);
}
}
question 2 how to remove the jitter/ noise from servos standing still ?(the servo's& arduino's power +- are from 1 source split up to 9 servo's .1 arduino to 1 servo and switch)
It seems i have many cable close crossing etc lenghts off 2 meters. from buton to arduino to servo is 3or 4 meters totall. the project is not @my home so the time is limited. I'm planing to do the cables nicely and shorten them and solder. could be off influence??..
i noticed that `1 arduino nano and 4 servo don't work and it need be on for hours and not jitter or make sound, therefore every servo apart works better in reality.
it is a short code please help me with the whole code because off time but i want to understand what i'm missing ,thanks !
