ParticleSensor. So first download the libraries from the link below and add it to the Arduino IDE Library folder. Apart from the MLX90614 Library, it also requires Blynk Library. The code requires MLX90614 Library for compilation. 17byte rates //Array of heart rates 18byte rateSpot = 0 19long lastBeat = 0 //Time at which the last beat occurred 20float beatsPerMinute 21int beatAvg 22 23#define SCREEN_WIDTH 128 // OLED display width, in pixels 24#define SCREEN_HEIGHT 32 // OLED display height, in pixels 25#define OLED_RESET - 1 // Reset pin # (or -1 if sharing Arduino reset pin) 26 27Adafruit_SSD1306 display ( SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET ) //Declaring the display name (display) 28 29 static const unsigned char PROGMEM logo2_bmp = 30 ĭisplay.begin(SSD1306_SWITCHCAPVCC, 0x3C) //Start the OLED display The Source Code/Program for NodeMCU ESP8266, MLX90614 & Blynk is written on Arduino IDE.
