DEATH

This project consists of a terrifying skull created from scratch with an Arduino Uno, some components (leds, a servo and a sensor), plastic, wood and pieces of clothing.

The terrifying skull represents the fictional character we know as DEATH. It is in the context of a cemetery, with skeletons of dead people on the floor. For a moment it seems that the character is dead, but once you approach him "Death" comes back to life and starts moving from side to side looking at you with his scary red eyes.

On the photos upload, we can observe how the circuit has been connected and its schematic view. Moreover, there is a video to show how it looks like finished.

Here you can find the flow diagram of the project to understand how the code works.

In order to make the death come alive and move, we must recreate the circuit of the Tinkercad image, in this way, along with the programmed code can be achieved.

First we have to take several cables to be able to connect the circuit in a protoboard. We will connect the motion sensors, the leds, we must apply the necessary jumpers and connections to have all the required GND and 5V inputs. 

1. Get the Arduino app in your laptop.
2. Download the code you see down below.
3. Open this link and download the ultrasonic sensor library. Install it on the program.
4. Store the two files in the same folder and open the Halloween one.
5. Connect the Arduino UNO to your computer and upload the code to it.
6. You can close the program, turn off your laptop and leave the Arduino aside for later.

First of all, we've bought a plastic skull with tissues.

Since the eyes of our "Death" will turn red, we prepared the skull so that we can insert the LEDs into each eye. With a cutter we made two small holes in the position of each eye, then we joined these LEDs with cables that will cross the skull in order to connect it to the base.

To make the skull move from side to side, we attached a PVC pipe to the chin of the skull previously cut with a cutter, this way we fit the skull to the base.

As the servo offers a small turning radius, before reaching the base, we designed a longer radius with a thin sheet of wood. With the help of a trocha we made a hole in the wood to attach the shaft to size (PVC tube), which will fix the tube and cause the movement of the turn to 140º.

This same tube is also used to run all the wiring from the skull LED lights connected to the base protoboard. In this way it helps us to have both the LEDs and the servo motor connected.

We got our box and slowly started to bring in our electronics. To achieve our goal, we drilled the necessary holes in our box to implement our electronics inside.

In order to put our servo properly, we made a hole in the lid of the box of its exact size where it was glued with silicone, but with the help of adhesive tape we fixed it so that it does not move or fall.

To insert the LEDs into the skull and connect them to our protoboard, we used some male-female wires and at the same time some wires joined by soldering, since the extension of the wire was about 45 centimeters.

To make our DEATH more real, we painted the base black and decorated it to simulate a graveyard.

First, we bought some small skeletons and separated the bones of each of them and glued them to the base with silicone in order to simulate the remains of dead people and create a more terrifying feeling.

Second, to simulate a real tombstone, we created a sheet of wood cut with a saw, giving it the familiar shape of a tombstone. We stuck this to the base, representing the grave of the dead, where we wrote with a black marker "RIP", to decorate it in a more original way.

With all the material we have come to achieve our project, which was to create a dead body that wakes up by moving and emitting light when someone is near.

Once again, we have seen that it is more fun to learn new things if you do it in an interactive way and taking them to real life.

This project has allowed us to put into practice everything we have learned about programming with Arduino and the purpose of each of the electronic components we have used.

We have managed to create our own Halloween decoration, implementing programming.
