Objectives:
 Be able to control LED’s by using a remote control
 Learn how to wire up an Infra-Red Sensor
By the end of this session:
 You will have made the following circuit with a receiver
which reacts to button presses on an IR remote control

Components:
Arduino Uno
Breadboard
IR Receiver
Resistors
1)
Connect the components
like in the diagram.
Make sure that the dome
side of the receiver and the
short
leg
of
the
capacitor point to the right
(away
from
the
Arduino).

2)
Plug the USB cable into the Arduino and
into the computer, then open up the
Arduino software. It should look like
this...
3)
Copy and paste the ‘IR Remote’ program (from the webpage where you
found this document) into the main window and click on Upload.
4)
Open the Serial Monitor window

5)
Press the Red button on the remote control, you should see a line of numbers on the screen, followed by text saying ‘No Match!’
6)
Copy (click and drag to select, then ‘ctrl+C’) the long line of numbers and
paste them (ctrl+V) inside the curly brackets on the following line:
7)
Upload the program
8)

9)
Press the Red button on the remote control, you should see a line of numbers on the screen, followed by text saying ‘RED!’
10)
Now press the yellow button on the remote control, copy the long line of
numbers and paste it into the following curly brackets:
11)
Upload the program
And open the Serial Monitor Window

12)
Press the Yellow button on the remote control, you should see a line of
numbers on the screen, followed by text saying ‘YELLOW!’
13)
Now press the green button on the remote control, copy the long line of
numbers and paste it into the following curly brackets:

15)
Press the Green button on the remote control, you should see a line of
numbers on the screen, followed by text saying ‘GREEN!’
16)
Once you have got this far, push the board with 3 LED’s into the Arduino
using pins GND, 13, 12 and 11 and watch what happens when you push
the red, yellow and green buttons!
Plug into these holes,
and make sure that it
is this way round
