Input
Ports
| Pin | Type | Description |
|---|---|---|
| Q | bit | Output: the current toggle value (0 or 1) |
Input has no inputs — it is the very first point of a circuit. The value is toggled by clicking the switch.
How It Works
Input is a signal source. Click to switch between 0 and 1: an active input glows orange, an inactive one stays gray. It serves as the circuit's input port.
During a test run, clicks are not needed: Inputs automatically take values from the truth table row by row. This is exactly how the checker "talks" to your circuit.
Usage
Input is available from the very first level, "Wire", and appears in every circuit of the course: without it, a truth table cannot be verified. Paired with Output it forms the full contract of a level: what we feed in — what we expect out.
For byte-wide work (8 bits as one number) use its big brother — BusInput with a 0–255 slider.
