What makes some shows and some movies are so excited?

The answer is… the effects …. I loved the luminous sword in "star wars" and the fantastic blue suit of " max steel" superhero. when I used some simple LEDs in my project, I discovered that they can color the world and that what they do in the shows. so I decided to get in this lovely fantastic world with something maybe new!. make a simple draw and make it move with my hand by using my phone and very simple components.

Step 1: Components:-

1- LED Matrix(16*32 )

You can find it in local market or on this link

2- Arduino mega

3- 1Sheeld board

4- your smartphone

5- breadboard

6- 14 (male – male) jumper wires

7- 5V 2A (2000mA) power supply ( for very high brightness and more than one LED matrix )

Step 2: Download Arduino Coding Software

If it is your first time for using Arduino you should download Arduino software for coding to can talk to your Arduino.

https://www.arduino.cc/en/main/software

https://www.arduino.cc/en/Guide/HomePage

Step 3: Download the Matrix Library

https://github.com/freetronics/DMD2

this one is better and easier than that one on "free electronics" site.

Step 4: Download 1sheeld Library

https://1sheeld.com/downloads/

Step 5: Download 1sheeld App on Your Phone

From store or

https://1sheeld.com/downloads/

Step 6: Extract Files

After you successfully downloaded the libraries, extract the files in Arduino's library directory “Path\UserName\Documents\Arduino\libraries”.

And rename them to DMD2 and oneSheeld.

Step 7: Change File

Enter to the DMD2 library and change the ( DMD2.cpp) with this one attached, it is only changed to work with mega different pins.

DMD2.cpp
Download

Step 8: Connect 1sheeld

Connect your 1sheeld board by following this link

https://1sheeld.com/tutorials/getting-started/

Step 9: Connect LED Matrix

If INPUT is not labeled, look for one or more arrows pointing in the horizontal direction (ignore any vertical arrows, whether up or down). The horizontal arrows show the direction data moves from INPUT to OUTPUT — then you know which connector is which.

To understand ribbon connector, visit this link

then connect the pins to Arduino like this in the schematic photo.

Step 10: Upload Code on Arduino

After connecting we are ready to use the code so connect Arduino to your computer and upload the code in the attached code file.

Download

Step 11: Use the 1sheeld App

Open your app and connect with 1sheeld, Activate accelerometer and click on the upper right triple-shield sign to see the values of your motion. Move your phone with hand to left and to right.

Small note:

The accelerometer is an acceleration sensor designed to calculate the simplest changes in the rate of movement in a certain direction, but existing applications today for this device are interested making Transducer for movement and positioning.

Now you can enjoy it.
