Devlog 4

I have finished my project!! Unfortunately, I don’t have a 3D printer and my access to a 3D printer has come up short in recent months so I can only submit a video of my project working.

What I have done since Devlog 3:

• I have fixed my SD card and Arduino Uno problems with a ESP32 which has more SRAM and can handle my program. (I decided to get rid of my SD card and display my data another way, keep reading)
• I used the switch button on my rotary encoder to switch modes between time and temp&humidity readings
• I added a motor to my design to act as a cooling fan
• Instead of the SD card collecting data I instead used the BLE capability of the ESP32 (Bluetooth low energy). This meant that every reading would be sent to the device hosting the website every 2 seconds (or however long I chose).
• Using the data from my project I displayed it on my website with graphs, adding a baseline to each variable (e.g. temp and light)
• Added a button on my website that if pressed sends a signal to the ESP32 to turn on the fan/motor, this way even if it doesn’t reach a temp threshold I could still use the motor as white noise or more cooling.
  (P.S. my website is local only)
• Finally I built 3D models for my parts which I won’t be able to print but would theoretically work to fit my components! ( I used fusion 360 for this).
