Hi, I am a Mechanical engineer graduated in Bari (Italy). I am passionate about 3D printing, 3D modelling and mechatronics.

I love working on different projects that I found online involving Arduino and 3D printing during my free time.

On this site you will find my latest as well as my future projects.

Step 1 : I 3D printed all the parts I needed for this project using the slicer software Ultimaker Cura. All the parts were designed by daGHIZmo .

Talking about the material of the filament I chose PLA because is less thermally contractive than other types of filaments which means it hardly ever warps and is very dimensionally stable, making it much easier to print big parts.

Step 2 : I assembled the base and the arm.

Step 3: I included the servo's library in the sketch (sketch-->#include library-->Servo).

I downloaded the code from this tutorials

https://www.italiantechproject.it/tutorial-arduino/servomotore

and I sended it to Arduino UNO.

#include <Servo.h>

#define PIN_SERVO 9

#define PIN_POTENZIOMETRO A0

Servo servo;

void setup(){

servo.attach(PIN_SERVO);

}

void loop(){

int input = analogRead(PIN_POTENZIOMETRO);

int angolo = map(input, 0, 1023, 0, 179);

servo.write(angolo);

delay(20);

}

Step 4: I connected the robotic arm with Arduino UNO in order to move it using a potentiometer.
