Week 1: April 10 - May 14

Individual Log - Zach

Proposal: Week 14 was spent exclusively revising the report with group members, and preparing both the slideshow and ourselves for the presentation.

Proposal: Week 15, I spent my time reading through most resources available on Arduino's website, including the nRF52840 manual, Arduino articles on its language, ecosystem, pinout and configurations, and supported libraries.

Proposal: Week 16, I spent roughly an hour preparing the website for next semester.

Project: Week 17, I began creating some of the pseudocode and flow chart for the thermostat, currently only a basic illustration has been created (see below). I rebuilt the circuit on a breadboard and included the to-92 L78l05 recommended by a member of the board. Using some of Arduino's examples from their website I familiarized myself with how to integrate different devices with the MCU in the most basic ways. Things achieved this week would be getting an output of the potentiometer displayed in the serial monitor and the LCD screen displaying information. Some experimentation was done with a buzzer, where the example provided plays 7 major scales (musical scales). While attempting to get the LCD screen working, it was discovered that SCL and SDA required 5VDC to operate correctly, and since the Arduino only supplies 3.3VDC from its GPIO, a level shifter was purchased to allow I2C communication to work properly.
