DenshaBekutoru - 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.
