Cheap Beginner Quadruped Robot

have you ever wanted to build your own robot well today i am here to tell you how to

Supplies

servos 4x

Arduino mega Uno

cardboard

jumper wires

Lego

hot glue

Step 1: Parts

hello this is my first inscrutable there will be not many pictures but i can talk you through it ok so the first step your gonna need.

Arduino mega Uno

4x servos

jumper wires

cardboard

Lego

ultrasonic sensor if you want it will still work without one

hot glue

Step 2: Assembly

first you cut out a square piece of cardboard once your done that glue the servos at the bottom then glue your Lego legs to the servo cap once don that wire it the wiring goes like this red=5v black=GND yellow=pin 2

do the same for black and red 3 other times for yellow attach the 3 remaining wires to pins 3 4 and 5

Step 3: The Code

const int pingPin = 12; //trig pin of arduino

int inPin = 11; //echo pin of arduino.

//range in cm which is considered safe to enter, anything

//coming within less than 5 cm triggers red LED

int safeZone = 95;

int tonepin=10;

int redPin= A7;

int purplePin = A5;

int bluePin = A3;

// defines pins numbers

// defines variables

#include
