3 McManus, Nazarenko, Perez, Wigger 3 Abstract The goal of this project was to create a coffee table that has interactive games, produce audio visual effects in real time that coincide with music, and have touch screen capabilities. Our interactive game called Engineering Hero was made using IR sensors and LED strands. The IR sensor gave touch screen capabilities and allowed for interaction between the player and the table. The audio visual effects were made using an Arduino Uno and an audio input that went through a Fourier Transform program. The program returned the magnitude for different frequency components of the music and was used to produce visual effects through a 10x15 LED array. Electrical circuit design and computer programming was used to implement all design components. The table has a unique design and has commercial potential. Before bringing it to market the design needs to be refined to reduce the cost of construction. Having an interactive coffee table would be great for a party, restaurant, and conversation piece. The table provides entertainment and still can be used as a functional piece of furniture on a daily basis. All of the design goals were met for this project. Future improvements would include a smaller power supply for the audio amplifier and more interactive games.

5 McManus, Nazarenko, Perez, Wigger 5 Introduction Background: The TAG table was designed for home entertainment and as a functional piece of furniture. The custom table was integrated with a touch screen, audiovisuals, Xbox controller, and games. Project purpose: The purpose of our project is to create a table that can play games, produce audio-visual effects in real time that coincide with content of an audio signal, and have touch screen capabilities. To complete this goal an Arduino Uno, LED matrix, and raw materials for the table will be used (see budget summary). Electrical circuit design and computer programming will be used to implement all design components. Design Objectives: Create a 10 x 15 array of RGB LEDs which will be controlled by an Arduino (Uno/Mega) Final array will be built into a table Table will have built in speakers powered by audio amplifiers used to play audio inputs Array will have several programs LEDs will respond to touch via IR emitters and detectors Array will display an audio visualizer in response to an audio input Display will be programmed to run several games (tic tac toe, pong, etc.) Xbox 360 controller(s) can be used to switch between display modes as well as to play games LCD screen will display which mode the display is running at any given time Design of our table was split into four categories: 1. Audio Amplification 2. Audio-Visual Effects 3. IR Touch Sensor Capability 4. Xbox Controller Implementation We chose to divide the overall project into four main parts as shown above. Each team member then chose an assignment to be responsible for completing. This division of work was necessary because it allowed for much more time allotted to each particular part of the project. With more time to focus on each part of the project the quality of the project was greatly increased from what it would have been otherwise.

6 McManus, Nazarenko, Perez, Wigger 6 Audio Amplifier Design Figure 1: Overall System Block Diagram Purpose: The purpose of this part of the design is to implement two speaker cones in the table. With the speakers the user will be able to listen to any audio input going into the table while also seeing how the display responds to the same input. Description: The table implements two 4 speaker cones with a 4 ohm Impedance on each cone. Any audio signal put into the table will go through an audio splitter cable to both the Arduino and the speakers. The speakers are powered by a cascaded JFET/op-amp/Class A-B amplifier. The design achieved a maximum gain of approximately 45 db over the audible frequency range (20-20k Hz). To test the frequency response of the amplifier a function generator and oscilloscope were used. The function generator served as a controlled input signal. For the tests a 10mV peak-to-peak signal was used while the frequency was varied over the range specified above. The oscilloscope was used to measure the input and output signals in order to measure the gain of the amplifier. Table 1 below shows the data collected from the testing which is shown on a bode plot in figure 4.

8 Gain McManus, Nazarenko, Perez, Wigger Amplifier Frequency Response Frequency (Hz) x 10 4 Audio-Visual Design Figure 4: Bode plot for amplifier frequency response Purpose: For the audio visual settings of the table the Arduino and the Arduino s FFT library was used. The table consists of a 10x15 LED array using LEDs that are driven by the LPD channel constantcurrent driver chip. The LEDs came in a strand of 50 and each LED is addressable because of the LPD6803 chip. Figure 5: Strand of LEDs with LPD6803 chip.

9 McManus, Nazarenko, Perez, Wigger 9 Using these strips gave us more time to develop programs and add other features to the table. They require 5v to operate and use two pins on the Arduino for the clock and data. The LPD6803 chip also includes a serial shift register and concatenation driver circuit. Figure 5 shows how two LEDs in the strand are connected. Figure 6: Schematic of two LEDs connected in a strand. Description: Based on the audio frequency the LEDs turn on and off. The pattern shown in figure 7 is the spectrum in real time as an audio signal is being played. Before building the full LED array a 5x10 array was built for programming and testing. This allowed us to become acquainted with the micro-controller and start basic music and light programs. The Arduino s FFT library takes a signal from one of its analog pins and performs a Fast Fourier Transform algorithm. That algorithm outputs the magnitudes at different frequencies in real time. With these magnitudes each LED was programmed to light on or off with different colors. A function to light up different columns was created to show the spectrum of the music that is being played. There are also other programs to light the LEDs to music. Once the programming and testing was completed with the smaller array the final design was constructed and tested.

10 McManus, Nazarenko, Perez, Wigger 10 Figure 7: Block diagram of audio visual design. Figure 8: Spectrum of music in real time. IR Touch Sensor Design Purpose: The touch controls of the LED table will enable user interaction to control modes, games, and other programs in an intuitive and simple manner. The goal is to make is familiar to use as a tablet or smartphone. Description: The touch sensor will be implemented using two infrared LEDs in 15 boxes of the table. One LED will act as the emitter and will be constantly on. The other will act as a detector that s waiting for the reflected infrared light that will cause current to flow through it. That current will then go through a resistor causing a voltage drop. This change in voltage will be detected by the Arduino and it will know that a touch has been initiated in that block. By using a large valued capacitor it was possible to make a more sensitivity sensor. A diagram and circuit schematic of this approach can be seen in figure 8.

11 McManus, Nazarenko, Perez, Wigger 11 Figure 9: Diagram and circuit schematic of infrared touch sensor. To implement a large number of these touch sensors, shift registers were used. Using two 8-bit shift registers it was possible to register the possible 15 touches on the table. By programming the Arduino to rapidly send one bit through the shift registers once a touch sensor is activated it will be registered by the Arduino. The code is then able to determine which block that sensor corresponds to. Because this is happening at a high rate multiple sensors can be triggered and to the naked eye it will look like the Arduino is sensing two touches simultaneously. Even though the program is actually turning on and off each block rapidly as it senses the touch the code had to be slowed down so that a touch could be easily measured. Figure 9 shows this concept. A 1 is being shift quickly through the register and the Arduino knows where the 1 is located at all times. When one of the touch sensors is activated it acts like a switch and delivers a voltage to one of the Arduino s analog inputs. An analog input was used for callibration purposes. When a certain thershold is registered the shifting program is haulted to idetify which touch sensor is activated. This information can then be used to turn on the LED associated with that sensor creating a light touch response on the table.

12 McManus, Nazarenko, Perez, Wigger 12 Figure 10: Shift register implemented with the touch sensors. It should be noted that in a bright room the sensing of touch is reversed. Since there is continuous light hitting the detector LED a touch sense is registered when light is being blocked. So instead of having the code register a high voltage input it now looks for a low input. Xbox Controller Implementation Design Purpose: The purpose of Xbox 360 controller implementation in our senior project is to allow the user to navigate through the subprograms in our code to either run our audio-visual program or our IR touch program. Description:

13 McManus, Nazarenko, Perez, Wigger 13 Figure 11: System diagram for Xbox controller implementation Utilizing the system illustrated in Figure 10 above, we can see how the Xbox 360 controller will connect to the main program structure. Note that this is an early structure; as the project progressed certain elements were changed (i.e. the breadboard became the table) and some block elements were not be on the table itself such as the computer.

15 McManus, Nazarenko, Perez, Wigger 15 Project Timeline Build and Testing Inside Each Cube: Underneath the plexiglass top there is an array of gardening trays which are separated into 150 two inch cubes. Inside every cube there is one RGB-LED. 15 of the cubes also included an IR emitter and detector. Underneath the Hood : Underneath the hood of the table is where all of the electronic components are stored. For ease of access hinges were built into the table so that the top can fold up. Testing: The first component tested was the RGB LEDs. This was done using the Arduino library for our LEDs by turning each one on and switching between the red, green, and blue colors to ensure proper functionality. Simple Arduino programs were written separately to test the different features of our table. The audio visuals were tested using different audio inputs to insure the same results were achieved for all types of music. Adjustments to the code had to be made to make the code more efficient and light the LEDs faster. Lastly, we tested the audio amplifier first by using a 1kHz sinusoidal

16 McManus, Nazarenko, Perez, Wigger 16 input and observing the output on an oscilloscope. After seeing an output signal that was amplified as expected we connected the speakers and used an audio signal to ensure full functionality. Results Every team member was successful in researching and developing their part of the TAG table. At the end we were able to integrate our components together to create a functional piece of furniture that also serves as home entertainment. We also won Most Creative Design within the ECE department for the design for our table at the Undergraduate Research Conference. Discussion and Conclusion Since there were many components to this project it was important we stayed on task throughout the year. Given that Michael Perez wanted to fund the project so he could keep the table, we had to consistently be aware of the fact that we needed to budget our project, which was an important economic constraint. Another ethical constraint we had to deal with was making sure to reference all of our code appropriately in our reports (see References and Acknowledgements section) since we used some code in our project that was provided online because the Arduino code is opensource. Every team member was successful in researching and developing their part of the TAG table. At the end we were able to integrate our components together to create a functional piece of furniture that also serves as home entertainment and abide by all of the professional standards taught to us in our Engineering Professional Principles course in the spring of last year.
