1× uses the entered speed: 15 rpm takes 4 seconds per turn. Drawing scale fits the frame and stays fixed during playback.

Parallelogram linkage: preserve orientation
Equal side arms and equal coupler/ground lengths keep the green coupler horizontal. Its path is an arc, so it moves sideways as well as vertically. This example drives the arms sinusoidally between 25° and 155°.

Blue is the prescribed input, green is the connecting link and red is the output. Change the blue dimensions, then use the button to return to the drawing. This page calculates motion, not the required motor force or torque.
