1. A sewing machine that sews a sewing pattern on a sewing object placed on a bed, the sewing machine comprising:
a sewing machine motor configured to drive a needle bar in an up-down direction;
a projector configured to project an image toward the bed;
a processor; and
a memory storing computer-readable instructions that, when executed by the processor, cause the processor to perform processes comprising:
generating processing of generating a first image including a first object representing a first sewing pattern, the first sewing pattern being at least a part of the sewing pattern and being a state in which a sewing by the sewing machine is incomplete, and generating a second image including a second object representing a second sewing pattern, the second sewing pattern being a part of the sewing pattern and being a state in which the sewing has progressed further than the first sewing pattern; and
projection processing of, after causing the projector to project the first image generated by the generating processing, switching the projected first image, during a driving of the needle bar by the sewing machine motor, to the second image generated by the generating processing, and causing the projector to project the second image.
