How to Control a Servo With a Single Pushbutton

Spectacular Crift-Hango.png

hi, this is my first instructable it is on how to control a single servo with a single pushbutton. I am using this circuit to animate a spiderman mask so it has moving lens. Please comment if you have any advice or uses for this circuit.

Supplies

Servo

Jumper Wires

Arduino Uno

Arduino IDE

Wiring the Servo

Brown wire from servo to ground

Red to 5v

orange/yellow to digital 2

one wire from the button should go to ground and the other to digital 3

Arduino Code

#include

const int buttonPin = 3;

int servoPin=2; Servo Servo1; i

nt buttonState = 0; int flag=0;

void setup(){

pinMode(buttonPin, INPUT_PULLUP);

Servo1.attach(servoPin); }

void loop(){

buttonState = digitalRead(buttonPin);

if (buttonState == LOW) {

if ( flag == 0)

{ Servo1.write(0);

delay(500); flag=1; //change flag variable }

else if ( flag == 1){

Servo1.write(70);

delay(500);

flag=0; //change flag variable again } } }
