 #include <Adafruit_SSD1306.h> 
 #include <BH1750.h> 
  
 #define OLED_RESET 22 // GPIO22 
 Adafruit_SSD1306 display(OLED_RESET); 
  
 BH1750 light(0x23); 
  
 void setup() { 
   Serial.begin(115200); 
   Wire.begin(8, 10); 
   display.begin(SSD1306_SWITCHCAPVCC, 0x3C); 
 } 
  
 void loop() { 
   // Clear the buffer. 
   display.clearDisplay(); 
   display.setTextSize(1); 
   display.setCursor(40, 10); 
   display.setTextColor(WHITE); 
  
   if (light.begin(BH1750::CONTINUOUS_HIGH_RES_MODE)) { 
     display.println("Light: "); 
     display.setTextSize(1); 
     display.setCursor(40, 21); 
     display.print(light.readLightLevel()); 
   } else { 
     display.println("Error!"); 
   } 
   display.display();
