We aimed to produce smaller circuit as much as we can for that purpose we consider to use LCD shield 4884 . Also output pins of servo can disable to try another one with control panel.

Learning how to react and rotate servo to given control signal is the other main theoretical part of construction. We focus on PWM and servo libary actions.

Codes are writen to construct given options in project by help of LCD 4884's own libary .Then necessary changes done to control servo to engage LCD's joystick and servo.
