Level 1: Let there be light!
Task
Connect the signal source (Input) to the receiver (Output).
The first level introduces you to the interface.
Solution
Two elements are already on the canvas: Input (signal source, left) and Output (receiver, right).
1. Hover over Input — you will see a small circle labeled Q. This is the output pin. 2. Output has a circle labeled D — input pin. 3. Hold the left mouse button on pin Q and drag a wire to pin D. Release — the connection is made.
Toggle the Input switch: when it glows orange (1), the Output lamp also lights up. The signal traveled!
