Mood Cue: Using a potentiometer to turn a servo to where I want

    This project was based around turning a servo motor a certain amount based on how we twisted a potentiometer. This was a very simple circuit to build, with the only three big parts being the servo, potentiometer, and the capacitor. The potentiometer is connected to the A0 pin, and the servo is connected to the ~9 digital pin. 


    The capacitor is meant to take care of voltage dips that could occur by smoothing them out. The potentiometer reads the angle on an analog basis, which is why it is attached to the analog output. We needed to use the male header pins to connect the servo to the board, which gave me pause for a minute because I didn't realize you could move the black plastic pieces down to even out the sides.


    The code for this project was super simple, just mapping the angle from the potentiometer to the servo, and changing the angle based on how much it is spun. The code also outputs the current angle based on how far the potentiometer is spun, shown below.



    This project has been the most fun so for. I found the color changing light and heat sensor projects really hard to control, and the first two were just super simple. But this one was simple to do, and had a really satisfying conclusion when I finished it. It was a fun project to complete, and also play around with!

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. ...
