+# 🔹 ProjectTracker_5VArduino_OpenPLC_TrainerBuild
+
+## 🔢 Hardware Setup
+- [ ] Mount Arduino Uno/Nano Every on base panel
+- [ ] Install breadboard (for LEDs and button wiring)
+- [ ] Wire Green Start Button (5V, INPUT_PULLUP)
+- [ ] Wire Red Stop Button (5V, INPUT_PULLUP)
+- [ ] Wire optional Fault Button (5V, INPUT_PULLUP)
+- [ ] Install and wire Green, Red, Yellow LEDs with 220Ω resistors
+- [ ] Connect 5V and GND rails cleanly (shared power)
+
+## 🔢 OpenPLC Software Setup
+- [ ] Flash OpenPLC firmware to Arduino
+- [ ] Confirm OpenPLC runtime can detect Arduino board
+- [ ] Create simple Ladder Logic program (Start/Stop latch)
+- [ ] Test button functionality inside OpenPLC Editor
+- [ ] Verify LED outputs toggle based on Ladder Logic
+
+## 🔢 Testing and Verification
+- [ ] Power cycle test (board restarts safely)
+- [ ] Manual button press test (physical and OpenPLC input response)
+- [ ] LED feedback test (correct LED for each state)
+- [ ] Safety/Fault testing (if optional fault button wired)
+
+---
+
+# 🔹 Project Tracker: 12V M5Stack StamPLC Industrial Trainer Build
+
+## 🔢 Hardware Setup
+- [ ] Mount StamPLC on trainer base panel
+- [ ] Wire 12V input power correctly (common ground for devices)
+- [ ] Install 22mm Green Start Button (NO contact)
+- [ ] Install 22mm Red Stop Button (NO contact)
+- [ ] Install 22mm Red Emergency Stop Button (NC contact preferred)
+- [ ] Wire 12V IR beam breaker sensors (future phase)
+- [ ] Mount relay control field (motor light control etc.)
+- [ ] Setup I2C GPIO expander (optional)
+
+## 🔢 Arduino/PlatformIO Software Setup
+- [ ] Setup PlatformIO project or Arduino IDE sketch for StamPLC
+- [ ] Confirm basic digital input reading (Start/Stop/E-Stop)
+- [ ] Confirm relay outputs activate correctly
+- [ ] Implement basic control logic (Start/Stop Motor, Light Control)
+- [ ] Plan future RS485 communication wiring
+
+## 🔢 Testing and Verification
+- [ ] Full power-up test (12V bus operational, safe GND sharing)
+- [ ] Button and LED response verification
+- [ ] Relay output verification (switching 12V loads)
+- [ ] Safety lockout testing (Emergency Stop triggers output shutdown)
+
+---
+
+# ✅ Final Notes
+- Progress milestones allow methodical development.
+- Clean wiring and GND management at each step.
+- Avoid mixing 5V and 12V systems during build/testing.
+- Expand modularly: add RS485, sensors, and advanced functions later.
