+
+Flyback Diode (for DC coils)
+
+Purpose: Protects other components from the inductive voltage spike generated when the relay’s coil is de-energized. This voltage spike can damage transistors or other switching components.
+Type: A simple 1N4007 diode or similar can be used.
+Placement: Connect the diode across the relay coil, with the cathode (striped side) to the positive voltage and the anode to the negative end of the coil.
+
+Capacitor (for Noise Suppression)
+
+Purpose: A capacitor can be added across the relay contacts to reduce arcing and noise caused by contact bounce, which can help reduce wear.
+Type: Use a ceramic or film capacitor, typically around 0.1 µF, rated for the expected voltage.
+Placement: Place the capacitor across the relay’s switching contacts. For high-voltage AC circuits, ensure the capacitor is rated accordingly (e.g., X2 type for AC line).

 Node.js Raspberry Pi Pellet Stove Controller, named after the Greek virgin goddess of the hearth.
 
 # About
-This project seeks to replace the OEM control panel on a Lennox Winslow PS40 pellet stove with a Raspberry Pi. I will be utilizing a Raspberry Pi Zero W, relays, and switches already installed on the pellet stove. I chose a Pi Zero W for its small form factor, the lack of pre-installed headers, its wireless connectivity, and familiarity with the platform. I had previously used an Arduino Nano for a much more rudimentary version of this project and found great difficulty in making adjustments to the code. Additionally the Raspberry Pi platform will allow for expansion in the future to include IoT controls and logging of usage utilizing networked databases. The project will be written using Node.js and the rpi-gpio Node module. I've chosen Node.js for its familiarity as well as ease of implementation of a web server for future expansion.
+This project seeks to replace the OEM control panel on a Lennox Winslow PS40 pellet stove with a Raspberry Pi. I am utilizing a Raspberry Pi 3 Model B+, relays, and temperature snap switches installed on the pellet stove. I chose a Pi 3 for its wireless connectivity and familiarity with the platform. I had previously used an Arduino Nano for a much more rudimentary version of this project and found great difficulty in making adjustments to the code. Additionally the Raspberry Pi platform will allow for expansion in the future to include IoT controls and logging of usage utilizing networked databases. The project will be written using Node.js to handle high-level logic and communications, calling Python scripts to handle interacting with GPIO. I'm now in the process of rewriting this project to a more modern v2. Previously I had settled on using deprecated versions of Node.js to maintain compatibility with various Pi GPIO modules, now I've decided to split the GPIO controls off to a small Python interface script.

+* Call python to check pin states and reset them
+* Establish connection to MQTT
+* Listen for messages published to MQTT
+
+### Auto-Start
+* Check pin states for safety
+* Power on igniter, 30 second pre-heat
+* Power on exhaust
+* Power on auger
+* Wait X minutes
+* Check Proof of Fire switch
+    * No Fire:
+        * Shutdown
+        * Alert
+    * Fire:
+        *Power off igniter

 # GPIO
 Three GPIO pins are used along with a common ground to control three relays, supplying 120VAC power to the igniter and combustion blower when appropriate, and supplying power to the auger motor in pulses. Two more GPIO pins are used to detect open/closed status of a temperature-controlled snap switch and a vacuum switch. Another temperature-controlled snap switch is used to supply power to the convection motor when the pellet stove has reached a suitable temperature. A final temperature-controlled snap switch us used to interrupt the circuit for the auger motor to shut the stove off when an over-temperature condition is met. I will be utilizing a OneWire DS18B20 temperature sensor to detect the temperature of air exiting the stove vents.

-Logic Goal:
-
-1. Start Script & Web Server
-2. Await a command from the user.
-3. Startup enables auger
-4. If auger is enabled, run the cycle command.
-5. Once per cycle, read then rewrite the config file for interoperability
-6. Set feed rate based on config.
