-Model Train direction Sensor
+Get **direction** and **speed** from motor power signals.  
+Target use case: **model trains**.
+
+- Detects polarity (+/–) to identify train direction  
+- Measures pulse width to calculate speed (% of maximum)  
+- Implemented with optocouplers and a state machine  
+- As small as possible, but I hope no SMD (beginner friendly)
+
+Project is in an early stage. Currently running tests on target hardware.  
+More information and documentation will follow.
