This video details how a windshield wiper motor works and how to control the speed of it by hacking the intermittent function and manually controlling it with basic electronic components found even in an arduino starter kit.
Part of a much bigger project by Team Crushing It to design, develop, and manufacture a DIY Ventilator made from car parts.
For clarification, speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement.
This means we are controlling the speed of the wiper motor by controlling the rate at which we cycle the motor. By increasing/decreasing the interval between cycles, we are increasing/decreasing the rate of the motor which increases/decreases the time rate of the wiper arm.
Normally on windshield wiper motors there are only two separate velocities as controlled by the low and high speed wire.
This design implements only one of those velocities as the 3D printed ventilator mechanically controlled the velocity through alternate cam's.
