This circuit provides complete speed con-trol over car's windshield wipers. They can be slowed down to any rate even down to four sweeps per minute. The controller has two principal circuits: The rate-determining circuit-a unijunction transistor connected as a freerunning oscillator, and the silicon-controlled rectifier which is the actuator.
