You are required to build a keypad system to control the turning of servo motor. You shall prompt user to key $-$ in the angle $(0-1800)$ by using keypad and display it on serial monitor. The servo motor shall be turn according to the value inserted by the user. If the user inserts invalid values, you shall ask the user to key in again. $1.$ Construct a flow chart for Arduino to performs as the project highlights. $2.$ Construct a complete schematic drawing Arduino and its modules. $3.$ Provide the necessary Arduino code that aligned with the project and also the schematic drawing in $($b$).$ Please solve no$.1,2$ snd $3.$ Show the schematic drawing
