Making a ZOETROPE: Combing a DC motor, Potentiometer, buttons, and a 9v to create a moving picture

    This project was based on a Zoetrope, a sort of "moving picture" that is created by spinning different frames of an image quickly in a circle so it "animates" to your eye. These animations usually have 16 frames, and can be slowed down or sped up based on how fast you rotate the motor.



    The parts include a DC motor, which spins super based on power input. The H bridge controls the DC motor through 4 input channels, and when combined with the potentiometer you can alter the speed of the Motor while it is running. There are two buttons for controlling when the motor is on, and what direction it spins in.


The 9v is connected to the right hand side of the board, and only powers the DC through the H-bridge. The buttons are connected to the 2 and 3 pins, with on off on 3, and directional change on 2. The three outputs go to the H-bridge where they regulate the DC motor. The motor speed is determined by the potentiometer, and the loop function checks to see the high and low states of the two switches, and manipulates the DC motor accordingly


This project was fun to make, as was a great level up in our skills. It started to combine more of the things we have learned (DC motor, potentiometer, H-bridge, buttons), into a complex build, rather than a simple circuit. It shows how far we have gotten since the beginning of this course, but also that there is way more to be improved upon and learned as-well.

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. ...
