Personal Project 1: Plant Problem

 Plant Problem

We as humans tend to forget about our household plants and they go without water. My goal is to use the Arduino to get the moisture level of the surrounding environment to tell us if we need to water the plant. I wanted to use a piezo to play different frequencies for how much water the plant needs.


Initial Setups

This is the initial setup that I built to do my trial run to get the values that the sensor will read.

This was the code I used to get the initial reads and the max value read 1023 and the min value was around 260. 




In this video it was a test to figure the min and max moisture levels. I use a mug of water to achieve this and went ahead to use the results to figure out my ranges for the frequencies.



During the testing I realized that the test build is going to be the final build as I do not need to change any of the circuit.















Final Coding

After getting the initial tests I went and created the frequencies and the appropriate variables to allow me to be able to do this.



This had worked out better than I thought it would. As the moisture in the sensor changed the sound the piezo would make did change. 


Final Thoughts

This coding was not built for every plant; the ranges will need to be altered per plant depending on how they live. In the following video because it had just rained there was no sound which is good because it should not be telling us to water the ground. I also used the ground outside since I dont own a plant. I also removed the sensor to show that its position could change the readins also showing that it will produce different sounds based on the reading. Remember that if you use this for a home plant and have animals or it's in a windy spot to fasten the sensor down. This project all in all is simple and easy to do and complete.

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
