    reçu en bon état et dans un délai bien plus court que celui indiqué (10 jours avant la date prévue initialement ) une patte du module I2C était légèrement plié mais rien de grave les premiers tests ont l'air de montrer que tous fonctionnent correctement je recommande le produit et le vendeur

    The 4 line by 20 char I2C LCD shown in the picture allows you to show diagnostic values or menus / phrases to meet your needs. I had show a smaller 16x2 LCD attached to line follower robot This displayed the reflected lights value as an example. The I2c address was 0x3f.

    Que des avantages !!! Fonctionne avec 4 fils dont 2 pour l'alimentation et 2 autres pour la communication avec Arduino. Bibliothèque utilisée : https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads/ (NewLiquid...) Programme test : #include #include LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE); void setup() { lcd.begin(20,4); lcd.setCursor(0,0); lcd.print("01234567890123456789"); lcd.setCursor(0,1); lcd.print("01234567890123456789"); lcd.setCursor(0,2);

    Configured and tested with an Arduino in less than 5 minutes. Example code for the photo. #include #include // set the LCD address to 0x27 for a 16 chars and 4 line display LiquidCrystal_PCF8574 lcd(0x27); // Bangood smile :) uint8_t l[] = { B00000,B10000,B11000,B01100,B00111,B00001,B00000,B00000}; uint8_t r[] = { B00000,B00001,B00011,B00110,B11100,B10000,B00000,B00000}; // Geekcreit small r uint8_t cr[] = { B11100,B10100,B11100,B11000,B10100,B00000,B00000,B00000}; void setup() { unsigned

    The package was really carefully packed and the display came to me undamaged. I praise and can recommend 👍👍👍

    Excellent 20x4 display. Blue background, white characters, exceptional legibility. It is equipped with an I2C interface that facilitates wiring by reducing it to only 4 wires. Two for the transmitted signal, two for the power supply
