Example of NRF52 with OLED Reference: #include #include #define LED_PIN 12 #define LED_COUNT 8 Adafruit_NeoPixel strip(LED_COUNT, LED_PIN); void setup() { Serial.begin(115200); strip.begin(); strip.show(); } void loop() { strip.clear(); strip.setPixelColor(1,0,0,255); strip.show(); delay(1000); strip.clear(); strip.setPixelColor(6,0,0,255); strip.show(); delay(1000); }

Use of RGB LEDs

Use of RGB LEDs This scenario presents how to handle the brightness control of the tri-coloured LEDs. Both LEDs are electrically bound and cannot be controlled independently. Those LEDs have 3 colour channels, controlled independently: R (Red), G (Green) and B (Blue). Mixing of those colours creates other ones, such as pink and violet. Each R G B channel can be controlled with a separate GPIO to switch it on or off or control brightness using a PWM signal, as presented in this tutorial.
