I learn more from my mistakes

I had a small setback.  I wanted a more permanent prototype than the breadboard.   My dad purchased a Raspberry PI prototyping hat.With this I can solder my components down for a more permanent prototype.   The hat I used wouldn't work after I soldered the parts  to the board. The test LED I programmed wouldn’t blink. I troubleshot it using a multimeter.  I “buzzed out”  the board by testing for continuity from every connection to every other connection.  I found out that there were shorts between pins on the board where they were not  supposed to be connected.  The hat was defective.    To be truthful, I am not sure if somehow it was caused by poor soldering.   Dad bought a new prototyping hat and it should arrive soon.  I hope the Raspberry PI was not damaged.  There is a parts shortage right now and they are not in supply on any of the websites.   I did get practice soldering components and desoldering components.

Conclusion

 I am happy with the results of this experiment. I feel that working hands on on a project from scratch taught me many things, and that this machine has satisfied its purpose.

Presenting my project

Image
 Yesterday, I got the opportunity to present my automatic watering machine to a group of engineers from the MTA. It was online and lasted approximately 10-15 minutes, where they asked questions and I explained to them the inner workings and reason for my machine. Today we got a letter detailing how they liked my presentation and how I demonstrated a level of hardware and software proficiency that surpasses that of many graduating college students, which needless to say has made me very happy. I hope I get more opportunities like this in the future to demonstrate my machine that would allow it to make an impact. Below is a slide from my presentation.

Code overview

Image
 First, the code defines the chip select, the data input/output, and the clock on the ADC0832-N chip. The input and output ports were connected due to the fact that there would never be a time where neither input nor output are high-z. In addition it made wiring simpler. Chip select goes high before going low in order to start the conversion. Then, the data in sets the chip to single, because I am not comparing two values. Afterwards, on the third clock, the chip goes odd. On the falling edge, when the clock goes zero off of the third clock, the chip switches to input. Then the chip loops clock 8 times, while it reads the input. Then, it loops another 8 times while reading the reverse input in reverse, and confirms if the two readings are the same. After this, chip select goes high, severing the conversion, the chip goes output, and the voltage is gotten by multiplying the analog value by 5/255
