Color Mixing Lamp: Using light detectors to detect change and output through RGB LED

    This project was centered around using phototransistors to detect light, and their output determines how strong the RGB's in the RGB LED shine. The RGB LED is an cathode LED, where the middle left pin is the common ground pin. The phototransistors are connected to the Analog pins 0 - 2, this is so they can detect a multitude of different light levels to output to the LED. The Phototransistors are polar, so a specific pin is either positive or negative.



    It was hard to control the light against the phototransistors since they were so close to each other. If I were to build this on my own recognizance, I would put the phototransistors further apart from each other so it would be easier to control how much light was going into each. Either that or find a contraption to put on each phototransistor so I could control it.


The code utilized the output functions of the phototransistors as the value to input into each respective node of the RGB LED. We hooked up the A0-2 pins as outputs, and gave their values to the RGB nodes.

Final Project: Reusing the Snake board design to create Tetris with the Arduino

Image
      This project is my final one, and I am super happy and sad to be at the end. I have learned so much in this course, and also had so much fun. There was a lot of creativity and design in making these projects, and I got to work hands on in NMID for the first time, which is something I will never say no to. This project layout will be the one I keep my Arduino as. The board setup works between my Snake and Tetris code, and is a great way to show what I learned in this class. The components for this one are the same as the Snake Arduino setup. The joystick is necessary for movement controls, like it was in Snake. Left and right move the pieces, down sends the pieces downwards, and up rotates the pieces so you can control their fit. The 8x8 LED array is meant to convey what the current game-board looks like, and when your current piece under control is moving. The last parts are the wire connectors, which connect the 5v, Ground, 8x8 LED array, and Joystick all to the Ar...

Art Meets Engineering: Using an Arduino compatible microphone to create light based on sound

Image
      This weeks project was based on using good engineering principals to create art. I tend not to be a very artistic person in general, but when I thought about art, I tend to think of movies, and moving colors, so I can up with the idea for colors to move based on the "strength" of your voice. While the piezo can detect stuff such as taps, I needed a microphone to detect actual sound input, so I had to order one off of Amazon. In the parts diagram below, swap out the piezo for the microphone, but everything else is exactly what I used. I connected all the regular LED's to digital pins 2-8 and 12, so that way I could just send a simple High/Low when I needed them on or off. I connected the RGB LED's pins to digital 9-11, so that way I could use the PWM technique to get analog results from a digital pin. I connected the final pin to ground. The microphone is connected to the 5V, ground, 0 digital pin, and the A0 analog pin to out put the digital and analog results. ...
