    OLED i2c display with arduino

    Thanks for the lesson, I butchered the provided code and mashed it up with code for reading a AM2302 temp sensor .... now I have something practical...a digital readout of temp and humidity. Make sure you get the right I2c address. way cool.#include <SPI.h>#include <Wire.h>#include "DHT.h"#include <Adafruit_SSD1306.h>#define OLED_RESET 4#define DHTPIN 2#define DHTTYPE DHT22 // DHT 22 (AM2302), AM2321DHT dht(DHTPIN, DHTTYPE);Adafruit_SSD1306 display(OLED_RESET);void setup() { Serial.begin(9600); display.begin(SSD1306_SWITCHCAPVCC, 0x3C); dht.begin();}void loop() { int h = dht.readHumidity(); // Read temperature as Fahrenheit (isFahrenheit = true) int f = dht.readTemperature(true); display.clearDisplay(); display.setTextSize(2); display.setTex...see more »Thanks for the lesson, I butchered the provided code and mashed it up with code for reading a AM2302 temp sensor .... now I have something practical...a digital readout of temp and humidity.
