Arduino project to check temperature and send it to one MQTT broker.

Arduino Uno board project that check the temperature of my home rack and send it to one MQTT broker.
Extra - Optionally it will turn on a light with a motion sensor when my home rack door is opened.
Compiled with arduino-mk linux package.

sketch.ino -> is the main program file.
Makefile -> the make file to compile it with arduino-mk.

The following libraries need to be downloaded to /usr/share/arduino/libraries/:

• Wire
• WiFi
• SPI
• Time
• Timezone

To upload skecth.ino sketch to arduino uno board just type:

$ fuser -k /dev/ttyACM0
$ make upload

Be sure to be in dialout group.

To connect to serial type:

$ screen /dev/ttyACM0 115200

Be sure to have in Serial.begin(115200) the same serial number.

Edit skecth.ino and specify user and passwords in the following lines (2):

pubClient.connect("Arduino Collector 1", "user", "passwd");
