The objective of this project was to make a case for an Arduino (MEGA).

This box need to open and close with a button and the other objective of this project was my developing 3D design.

Step 1: Design

For the design of this arduino box I used the trinkerCAD

Step 2: The Box

Step 3: Problems

I went through many problems since making the hinge to where and how to place the button.

Step 4: Attempts Servos Arm

Step 5: Servo´s Arm

Step 6: Programming

//Button Toggle Servo


Servo servo; // create servo object to control a servo

// twelve servo objects can be created on most boards

const int buttonPin = 2;

boolean lastState = LOW;//storage for last button state

boolean pos = true;

void setup()


servo.attach(9); // attaches the servo on pin 9 to the servo object

pinMode(buttonPin, INPUT_PULLUP);//this time we will set the pin as INPUT

Serial.begin(9600);//initialize Serial connection


void loop()


boolean currentState = digitalRead(buttonPin);

if (currentState == LOW && lastState == HIGH)


Serial.println(pos ? "up" : "down");

servo.write(pos ? 90 : 0);


pos = !pos;


lastState = currentState;

<p>Very nice work; I am sure you will be able to customize this to suit many creations.</p><p>Thank you for sharing.</p><p>Build_it_Bob</p>
<p>Quite interesting. Thanks.</p>
<p>Cool Arduino case</p>
<p>Thank you ! </p>
