Esplora TFT Temperature Display
|
||
|
|
|
||
|
|
This example for the Arduino TFT screen is for use
|
||
|
|
with an Arduino Esplora.
|
||
|
|
|
||
|
|
This example reads the temperature of the Esplora's
|
||
|
|
on board thermisistor and displays it on an attached
|
||
|
|
LCD screen, updating every second.
|
||
|
|
|
||
|
|
This example code is in the public domain.
