We bring you a function that allows to reduce the brightness of the OLED SSD1306 screen connected to our Arduino.
We add this code using the Adafruit library:
adafruit/Adafruit SSD1306@^2.5.7 adafruit/Adafruit GFX Library@^1.11.9
We create this function:
void OledDisplay::brightness(uint8_t level)
{
display.ssd1306_command(SSD1306_SETCONTRAST);
display.ssd1306_command(level);
}
We can add values in the range: 0-255
For level = 255, all pixels turn on → maximum brightness.
For level = 127, about half will be lit -> average brightness.
For level = 20, few points will light up -> very dim.
