Project 1 - Wiper control system and Vehicle speed calculation for ABS using Wheel Speed sensor

1. Wiper control system

Develop Simulink/state flow model for wiper control system based on the given conditions.

Description of Challenge:

1. If the density of the rain is low, then wiper rotates with low speed & the output signal should be 100rpm
2. If the density of the rain is medium, then wiper rotates with medium speed & the output signal should be 200rpm
3. If the density of the rain is high, then wiper rotates with high speed & the output signal should be 500rpm

Note: Rain density input comes from the external sensor, for the simulation purpose constant block with knob can be taken
