Taking our hello world I2C OLED example a bit further, this is our next creation. We connect a DS18B20 temperature sensor and display the temperature on the display
Coding
You need to download and install various libraries and copy them into your Arduino libraries folder.
Dallas 18b20 Temperature Library
“1-Wire” Library
[c]
#include “Arduino.h”
#include “Wire.h”
#include “OneWire.h”
#include “MicroLCD.h”
#include “DallasTemperature.h”
#define DS18B20 2
OneWire ourWire(DS18B20);
DallasTemperature sensors(&ourWire);
//LCD_SH1106 lcd; /* for SH1106 OLED module */
LCD_SSD1306 lcd; /* for SSD1306 OLED module */
void setup()
{
lcd.begin();
sensors.begin();
}
void loop()
{
sensors.requestTemperatures();
lcd.clear();
lcd.setFontSize(FONT_SIZE_MEDIUM);
lcd.print(sensors.getTempCByIndex(0));
lcd.print(” celsius”);
delay(1000);
}
