== Key Coin Drop Signal Parameters ==

=== Pulse Width ===
- The duration of each pulse signal sent when a coin is detected. Example: If set to 50 ms, each coin generates a 50 ms “high” or “low” signal.

- Too short → controller may miss the pulse. 

- Too long → may cause double-counting.

=== Pulse Delay ===
- The time gap between consecutive pulses for multi-pulse coins (e.g., a $1 might send 5 pulses,  ).

- Ensures the controller can distinguish between pulses of the same coin vs. pulses from multiple coins.

=== Coin Signal Sensitive ===
- Defines how responsive the system is to signal changes.

- Higher sensitivity → detects even small voltage changes (risk of false triggers).

- Lower sensitivity → ignores noise but may miss weak signals.

=== Coin Signal Idle Level ===
- The default state of the signal line when no coin is inserted.

- Can be High (logic 1) or Low (logic 0) depending on the coin acceptor design.

- Important so the controller knows what “resting” looks like.

=== Coin Signal Width ===
- Similar to pulse width, but sometimes refers to the expected width range the controller accepts as valid.

- Example: Accept pulses between 40–60 ms, reject anything outside that range.

=== Pulse Pull Down or Up ===
- Defines whether the signal line is pulled to ground (pull-down) or to Vcc (pull-up) when active.

- Pull-up → idle high, pulse goes low.

- Pull-down → idle low, pulse goes high.

- Must match the coin acceptor’s wiring to avoid inverted signals.
