kindly help me in this arduino project

16 H+ 0.0K/s O.ilI 61% 11:30 Homework_5 ME435L Homework 5-Motor Speed Control Learning Objective: Arduino Analog & Digital IO Problem: Build the circuit given below and write a program that achieves following functionality. Button is used for power on/off of the whole system. Potentiometer is used to control the speed of the DC motor and LED turns on when system is on otherwise stays off. Circuit OO UNO AROUTNON rere EEPR Hints: There are 4 independent sub circuits. Program and verify that each sub circuit works independently. Use the Serial Monitor for verifying button and potentiometer circuit. Remember to scale the input on A pin (range is 0-1023) to PWM output on pin 3 (range is 0-255). For button functionality, refer to Lab 4, Section 2, Part 5. Note we are using external pull down on pin 2 too avoid the floating pin problem.
