3 button to controlling DC motor

Use 3 button to control DC motor

Purpose :           3 button : forward, stop and reverse which use 4 relay  5v to control DC motor.

              In this project, I have 3 button to control DC motor. First motor use for forward , second use for stop, third use for reverse. For this process, I also use 4 relay 5V to control motor when the current run after I push the button. It mean that, when I push first button(forward) current run into relay then metal of relay shock metal from NC to NO then motor run forward. After taking hand of it still run if relay connected to the voltage(5V) . Then I push button 2(stop) motor  stop. After that I push button 3 other relay will normal open and connect to com and motor run reverse. So it mean that, button forward and button reverse need 2 relay for each to control DC motor ( relay 1 for control motor and 1 more for keep there voltage(5V).
