Project 12: Knock Lock

 Homework 12: Knock Lock

For this project we are going to be making a knock lock. It requires x amount of knocks to unlock. The main component this time is the piezo not for output but as an input to hear the knocks to see how many knocks we have left. I went ahead and put the circuit together and included a schematic view with the components.













Coding 


This time with the coding it was a bit more general. It was alot of if statements for each state that the lock is in and if we are knocking. It is simple but just more code to have the program work. I also switched my leds so double check when coding the numbers line up with the leds you chose






Finished Product


This project was a little more time consuming as the circuit took a little bit to create and the coding also took a bit to do, but the project was fun and simplistic and created a nice little lock that could be used to create a secret knock with enough coding.

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

       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
