Så här kopplar du 1602 LCD blå bakgrundsbelysning med I2C förlött till en Arduino UNO eller ESP32, med ett exempelsketch som du kan ladda upp direkt.
Connect the 1602 I2C LCD display to the Arduino Uno using just four wires. The sketch initializes the display, enables the backlight, and shows a greeting along with a live uptime counter updated every second. Adjust the small potentiometer on the back of the module if the text appears too faint or dark.
