I2C Programmable PWMs to Control a DC Motor and LED

This project is based on the DS1050 chip, a 5-bit pulse-width modulator (PWM) controlled via a 2-wire (I²C) interface. The 2-wire bus allows a single master device to control up to eight slave devices (DS1050 or other compatible 2-wire peripherals). The project consists of a DS1050 I²C PWM generator combined with a MOSFET stage capable of driving high-current loads. It is primarily designed for driving LEDs and resistive loads, but it can also be used with inductive loads when an external flyback diode is added to protect against back-EMF.
