The the increasing complexity of P.Comp concepts continues to stretch my emotions and patience. It's either trying to see the connection of tiny pins and lines, or remember all the syntax vocabulary. Either way, these circuits they haunt my pre-sleep thoughts and make me eat a lot more snacks than is healthy. I wonder if I will develop PTSD and a beer belly at the end of this semester.
Feelings aside. I learned a couple of general concepts by attempting the labs.
Things I learned. First, there are two different sides for the pins. Analog devices like a potentiometer must be connected to the analog side. Two, the positions of the connections for the lines can be identified based off the function of the transducer. The lines connecting the Arduino to the reading transducers must connect to ground. The lines connecting to the Writing parts of the Arduino must be powered by the Arduino.
This little thingy-ma-doodle was my first source of validation in this class. I know that the lines are messy, but my wire stripper hasn't arrived yet and it's just easier to use these lines than waste a bunch of material.
The Code for it:
I think in this code there are a couple of main ideas to take note of. There are three levels. The top is the global level which is responsible for bringing variables into existence and setting rules overall. Set up is responsible for determining the nature of the transducer parts- whether its INPUT or OUTPUT. And finally, Loop cycles the functions of the code so that it can persist over time.
Loop can be broken up into two categories if it is an interactive part. If, stands for the condition of interactivity and what transducer output does. Else, stands for the times when If is not enacted.
Combination Lock
From this first lab, it opened me up to try more difficult circuits involving analog transducer parts. Below, I made a combination lock. I made so many mistakes in this project. This is also the project that inspired my dramatic unveiling in the video located at the top of this blog.
Before I get into what I learned from trying to make this combination lock. I have to get into my most embarrassing moment this week :/ I struggled with this project for around 3 hours to find out there was nothing wrong with my code and that my ground line was connected to the wrong pin. And I had to book help with Tommy Igoe to find that out. It's sad.
Anyways, In this lab, I learned how to use the serial monitor which checks the values of the part you ask it to read. I also learned how to reduce the range that Arduino reads on a particular part. but, the main lesson was a life message that applies outside of troubleshooting. It's the simplest things that people overlook.
Pressure Sensor
This project was easier to set up than the previous ones, but also more rewarding. As someone who wants to make projects that involve bodily interactions like heart rate sensors, etc. I think that my experience setting up the breadboard and programming this interaction could connect smoothly to that vision.
That's all I have to share for this week. Peace Out Homie!
