Overview – TA0136
In this instruction, we will introduce you through the fun project of the Arduino 2 Wheel Drive
Ultrasonic Robot Kit. Get your Arduino board kit. Let’s get started!
Getting started: the 2 Wheel Drive Ultrasonic Robot Kit
using Arduino UNO
2.1.What is Arduino?
Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino
boards can read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into
an output - activating a motor, turning on an LED, publishing something online. You can tell your
board what to do by sending a set of instructions to the microcontroller on the board. To do so you use
the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on
Processing.
2.2.What is IDUINO UNO?
The Iduino Uno is on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as
PWM outputs), 6 analogue inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an
ICSP header, and a reset button.
It contains everything needed to support the microcontroller; simply connect it to a computer with a
USB cable or power it with a AC-to-DC adapter or battery to get started.

Software installation
In this section, we will introduce you the development platform where you translate creative mind
into codes and let it fly.
3.1.Arduino Software/IDE
Download from here. Open Windows-based app by double clicking it and follow the instruction to
complete(Remember to install everything driver for Arduino). Easy!
Figure 1 Installation of drivers
Connecting your UNO board with your computer
Connecting UNO and your PC by a blue USB cable, and if connected correctly you will see the green
power LED light up and another orange LED is blinking.
Figure 2 Check Your special COM and note it down the number
Find your Serial COM
number and note it down.
We need to figure out which channel COM is currently communicating between PC and UNO.
Following the path: Control panel | Hardware and Sound | Devices and Printers | Device Manager |
Ports (COM & LPT) | Arduino UNO (COMx)

Note down the COM number as we require this later. As the COM port may vary from time to time,
this step is vital. In this case for demonstration purpose, we are using the COM 4.
3.2.Play with your first “Hello World” LED example
Firstly, let’s tell IDE where to find our Arduino port and which board you are currently using: The
following instruction (Figure 3 and 4) shows the details:
Configuration of Ports
Configuration of the Board

It’s time to play with you first simple example. Following the path by File | Examples | 01. Basics |
Blink. A new code window would pop up, press the arrow symbol to upload. You will notice the
orange LED is blinking almost every second.
3.3.Run your Arduino 2 Wheel Drive code
Upload to UNO
Done uploading!

Gather the following components:
1. 2 x Acrylic Motor
Brackets
2. 4 x M3 35mm Screws
3. 2 x Nuts
*Attaching wheel encoders are
optional. These are not required

Place acrylic DC motor Brackets
on both side of the motors as
shown on the left
Gather another two acrylic
fasteners and two wheels
Insert the acrylic fasteners first in
pre-cut slot

Chapter 4

Then tighten and secure the DC
motor with one nut on the other
side
Fix the other motor as well
Pull the wire through as we need
to connect them to the L289N
board

4.3.Arduino Installation
Let’s fix the Arduino UNO and Sensor shield in the following steps.
Prepare the jumper cables
Separate the jumper cable set
into four and eight
configurations
Connect the 8 jumpers with
L289N board as shown.
Please Note: The 8 Jumper
cables will eventually attach to
the Sensor Expansion Board
from the L289N board a few
