The pulse width modulation is the old method to control the power across the load by changing in the Duty cycle 0% duty cycle mean it,s DC and 50% duty cycle mean that it,s On for halftime and Off for the halftime.The hex keypad is connected with Arduino Uno by pressing the buttons on Hex keypad you can control the speed of the dc motor Like

key "1" = 16%) key "2" = 32%) key "3" = 48%) key "A" = 0%)
key "4" = 64%) key "4" = 64%) key "5" = 80%) key "6" = 96%) key "B" = 100%)
