Log the temperature values in a graph.
Log the temperature on a B4A application.
The temperature sensor TMP36 is placed with its 3 pins on a breadboard. Looking at the flat side of the sensor, the pins are connected:
Pin 1 (left) +5V
Pin 2 (middle) Analog 0 (A0)
Pin 3 (right) Ground (GND)
The Arduino UNO is connected with a PC via USB. The PC Port is COM4. The data is logged every 5 seconds on the Arduino and send to the serial line. The B4J application on the PC waits for data and when data received, it is being logged.
Lookup the Arduino Sketchbook and the B4J project code for details.
