DEVLOG #3 - Some Fixes
I modified the README.md for more clarity and fixed some logic errors in the code that prevented the alarm from running after it activated for the first time. But it was just fixing those errors and then I also discovered that Platform.io doesn’t let you have multiple .cpp files in the src folder that contain the setup() and loop() functions so I also had to restructure the platformio.ini project configuration file for multiple environments. I think all the errors are fixed, but I will update it in the future if there are any more.

DEVLOG #2 - Finished Product

Initially I had planned to make an ESP32 based version that had a locally hosted website and more features such as a temperature and humidity sensor, a proximity sensor, and a screen. However, the Proof of Concept I made is actually doing it’s job sufficiently and to ensure I have time to work on my other projects, I am going to stop this project here. However, before stopping I used some paper and tape to make a dust cover for the electronics.

DEVLOG #1 - A Proof of Concept

The ultimate goal of this project is to automate my bedroom’s light switch to help me wake up in the morning.

Although existing solutions such as smart lighting from companies like Phillip’s Hue exist, I wanted to try a system that is fitted on top of my existing switches and is relatively inexpensive. To accomplish this, I use a servo to actuate my light switch into the “on” position and prevent me from switching it off until some time has gone by.

While I intend to eventually use an ESP32 to make use of it’s WiFi capabilities. To try and get a rudimentary version up and running as fast as possible, I used the following components:

        - Arduino UNO R3,
        - SG90 9g microservo
        - DS1307 RTC Module
        - Breadboard
        - Male to Male Dupont Wires
        - Male to Female Dupont Wires
        - Powersupply that plugs into the wall
        - Foamboard
        - Tape

The current system uses a preset time which once reached causes the servo to actuate and flip the switch and then the servo goes into a position to prevent the switch from being flipped back.

This was just a short venture into a Proof of Concept for this device, but I intend to make the ESP32 Version significantly more robust and potentially include temperature monitoring, buzzers for sound, a display, and a 3D printed housing.

I added PID control to a cart & pole simulation on python, hopefully I can experiment with LQR in the future to get the system to both balance the pole and to keep the cart at a specific position so it doesn’t keep going off the screen.
