Creepy Simple Animatronic Skull Gardener

This is the Animatronic Skull Gardener for the Halloween 2017.
This year for Halloween, I have finally build the first operational prototype of my animatronic ! That's take me many time to build it and make instruction.

So, I will show you how to build this simple and cool animatronic.

What do you need ?

Tools:

-Electric drill

-Reciprocating saw (or a simple wood saw)

-Manual drill

-Screwdriver

Step 1: The Arms

Build the 2 arms

Step 2: The Legs

Build the 2 legs.

Step 3: The Body (part 1)

Start to build the body.

Step 4: The Body (part 2)

Finish to build the body.

Step 5: First Assembly

Assemble the arms on the body.

Step 6: Second Assembly

Assemble the legs on the body.

Step 7: The Legs Padding

Add the padding of the legs.

Step 8: The Arms Padding

Add the padding of the arms.

Step 9: The Head

Add the 2 red leds to the head

Step 10: The Neck

Build the neck.

Step 11: Third Assembly

Assemble the head on the neck.

Step 12: Thourth Assembly

Assemble the head on the body.

Step 13: The Relay Module

Step 14: The Arduino Nano

The arduino software:

#include Servo servo1;

const int movedsensor = A4;

const int relay1 = 6;

const int relay2 = 8;

const int eyes = 4;

void setup() {

Serial.begin(9600);

pinMode(relay1, OUTPUT);

pinMode(relys2, OUTPUT); pinMode(eyes, OUTPUT);

pinMode(movedsensor, INPUT);

servo1.attach(12);

servo1.write(90);

digitalWrite(relay1, HIGH);

digitalWrite(relay2, HIGH);

delay(500);

}

void loop() {

int a = analogRead(movedsensor);

Serial.println(a);

if(a >= 400){

servo1.write(180);

digitalWrite(relay1, LOW);

digitalWrite(relay2, LOW);

digitalWrite(eyes, HIGH);

delay(3000);

servo1.write(90);

digitalWrite(relay1, HIGH);

digitalWrite(relay2, HIGH);

digitalWrite(eyes, LOW);

delay(5500);

}

}

Step 15: Final Assembly

Step 16: Well Done !

Well... it's finnaly done !
