Living Pixel

As smart home products become increasingly prevalent, Questions about the dynamics between people and these devices. If smart home products become an essential part of everyone's life, how should we approach our relationship with them? How do we envision our interactions with these products?

In this content, I made improvements to the product I developed by referring to the Living Pixel tutorial.

Bill of Materials:

• 16x16 LED Matrix
• Frame
• Arduino Uno
• PIR sensor
• Power Bank (Philips 10000 mAh) (can be any brand)
• Stranded-core wire in two colors
• Resistors
• Flush Cutter
• Solder
• Soldering iron
• Glue gun
• Glue sticks
• Foam

• Prepare everything from the bill of materials.

• Please ensure to verify the size of the LED matrix you have purchased against the provided grid in the file before cutting. If you have a different size than the one listed, such as an 8x8 LED matrix, adjustments will be necessary, including integrating the corresponding code.

• Build your circuit according to the circuit diagram. You can test them on a breadboard first before soldering them together.
• Plugin your Arduino board to your computer.
• Download Arduino IDE if you haven’t already. Copy the code and run it in your Arduino IDE. Don’t forget to install the Adafruit NeoMatrix libraries before running the code if you never used an LED matrix before. Read this Adafruit-NeoPixel-Uberguide about NeoMatrix libraries, it will tell you the basics about NeoMatrix and how to install the libraries.
• Download the code provided and upload the code to your Arduino.
• Close the camera with a paper cup and see if the matrix is showing in the right way. If not, go back to the circuit and start troubleshooting.
• Meanwhile, you should set the sensitivity of the PIR sensor with the help of screws. The sensor is the main controller in this circuit so you need to observe the interaction between your movement and the sensor capture while setting the sensitivity. (like in photos)
• You’ve finished building the circuit! Let’s move on to assembly.

• Cut the frame (piece 1) accordingly LED matrix (16x16)
• Then cut the plastic of frame (piece2) to fit the PIR sensor.
• Put foam under the LED matrix.
• Put the PIR sensor under piece 2 and use the glue gun to fix it in position.
• Put them together in the frame, and if necessary, again use a glue gun to fix them in position to foam.
• Fix the Arduino board in the back of the frame with the glue gun.
• Yeah! This project is almost done. Let’s plug it in and start testing.

• Plugin the Arduino Uno with your computer. Set a true position for the sensor (like in front of you)  then close the sensor with your hand and see the reaction of the screen.
• if the sensor is late, then go back to the step that setting the sensor.
• Congratulations! You have finished this tutorial!
