Ito ang dapat mong maging wakas na resulta pagkatapos na magkasama ito at mai-upload ang code.

Hakbang 1: Mga Bagay na Kakailanganin Mo

Jumper Wires, 220 OHM resistor, 16x2 LCD Screen, Push Buttons, Servo Motor, Breadboard, Arduino Uno.

Hakbang 2: Code

kapag tapos lahat dapat ganito ang hitsura.
