Project 8: Digital Hourglass

Homework 8: Digital Hourglass

For this project we are going to be making a digital hourglass. This project will utilize the tilt sensors and Led’s. The tilt sensor will tell us when to reset our code to restart the lighting process. I went ahead and built the circuit and added the components list and a schematic view.


Coding 

The coding this time introduced a new function and use. We had used millis() before but this time we use it to check how much time has passed. We don't use delay because we still want the rest of the code to function. The code has a few spots for user rewrite. There is an if(led==7) you can do what you want, maybe play a sound or something else. I also edited the interval so that in the video at the end you can see it work. The tilt sensor's location is how we know when to reset the lightening process.


Finished Product

After adding user touches and getting everything hooked up, we get a nice little digital hourglass that has the user capability to expand on this project. I liked this one and it was interesting. I was smart after the last project to get my resistors labeled so I can have an easier time figuring out which is which.

Personal Project 3: Etch A Sketch

Image
  Etch-A-Sketch I needed to make something with the arduino and something art related. So with two knobs and a screen to draw on I thought I could recreate the etch a sketch. The etch a sketch would fulfill the requirements and a fun little thing to make. Initial Setups This is the initial build I used for my testing to make sure that I can get different values for each potentiometer and a value from the tilt sensor. .  This was the code I used to get the initial reads and would make sure that I would be sending the proper data. I did come across an issue here with the mapping and have it solved later. My unity was a blank 2d core and I created a small square prefab.  This is my final setup and parts list. The values i got from the potentiometer were correct and the sensor would detect when tilted. Final Coding Arduino: This was a total of 40 lines of code on the Arduino side. The delay is a little bit lower so that more will get drawn to the screen. I also had to do the map function

Personal Project 4: Clap Lights

Image
       Light Clap I needed to address an issue that could be solved with an Arduino. I went ahead with the idea of when you're in bed with the lights still on. So, with the use of sound, we can change the state of the Leds. I would have it programmed to work with a rgb strip but  Initial Setups This is the initial build I used for my testing to make sure that I can get my lights to light up and test to see if i can get values from the piezo.  This is the code I used to make sure the circuit worked, and all the lights lit up. I just used hard coded values for testing and would later change it to have only certain ones light up. This is my final setup and parts list. I successfully got the value to light the Leds up and the value from the piezo were in tolerance. Final Coding Arduino: I got the code together to make it have different states of lit up lights to replicate an RGB strip. The code was pretty simple. The code to make it so that the clap will change the states is the same

Personal Project 2: Tic Tac Toe

Image
  Tic Tac Toe I needed to make an alternative controller, so I made one for tic tac toe that is run in unity. I went with tic ta toe because I have the pieces to make it and the knowledge to do it. I went with unity due to past experience in the program. Initial Setups This is the initial build i used to test my buttons. This resistor ladder is just like the one used in project 7.  This was the code I used to get the initial reads and make sure that I am still getting the same results as the project 7.  This is what my unity sketch looks like. I made no real changes to it, just got rid of the circle in the top spot. I was using it to determine where the pieces were going to go. This is my final setup and parts list. The double resistor ladder on each side of the board was nice and can be used with further coding for other things. Final Coding Arduino: There is a lot of coding, but it is mostly just simple stuff of just checking if the value is what we want and the printing the data t
