Make: Robotic Arms

STEP 4

#include <Servo.h>

Servo servoOne;

int pos;

void setup() {

Serial.begin(9600);

servoOne.attach(3);

}

void loop() {

pos = analogRead(A0);

pos = map(pos, 0, 1023, 0, 180);

servoOne.write(pos);

Serial.print("Servo Position: ");

Serial.println(pos);

delay(100);

}

OK—we have added the code for our servo back in, and if all goes as

planned, once you upload the latest version of the code, as you turn the knob

on your potentiometer, your servo should move accordingly. With that, we

now have a few servo control examples under our belt, and we’re ready to

build our first robotic arm.
