This is a list of
everything you will need to build your own LED Color Thermometer, and
bellow that step by step instructions
for completing the
SML-LX1610RGBW/A RGB LED
3021-A-I-350 LED Supply x3
Black, Red, Green, Blue, White"
Ohm resistor x2
battery with connectors x4
sink for LED
I2Cmaster.zip-library for reading the sensor
thermophoto.ino-script to run on arduion
Step by step for do it yourself:
1. Lets start
by assempling the following circuit!
For now just build this on the breadboard.
2. Now for the LED setup. This
one is a touch more complicated and requires the use of a saudering
Here is a
picture of how to sauder the LED/buck puck cercuit.
Connect the Red, Green and Blue
signal wires to arduino ports, 9, 10 and 11 respectivly and the ground
to the same ground as the
arduino on your bread board.
3. Now lets get this thing
file called I2Cmaster (found after downloading and unziping from the
link provided) in Arduino/libraries.
thermophoto.ino as a sketch.
Connect the four 9V bateries
a) Plug the arduino into a USB port.
thermophoto.ino in arduino and upload it to the device, by clicking the
button in the top left of the tool bar, (kinda like a
c) Stick your
hand infrot of the sensor, and if all has been done correctly the light
should go red!
If you want
to see a running descriptor of the temperature, open the Serial Monitor
(located at the far right of the toolbar).
*Bateries must be
fully charged! Beware this device chews through the bateries!*
4. Housing the device is a mater
of prefrence. Here is how I did it.
-Spray paint the
shoebox and toilet paper tube, black.
-Glue the toilit
paper tube over the LED on the heat sink.
-Cut hole in shoe
box and put tube through the hole.
-Cut a small whole
in the box nex to the LED tube so that the wires of the sensor may lead
back into the box.
breadbored to the bottom of the Shoebox and tape baterries down aswell
so that they do not move.
Guid is incomplete, if you have any questions please
me personaly and I would be glad to help!
