BlinkRGB
|

|
|
||
|
|
Demonstrates usage of onboard RGB LED on some ESP dev boards.
|
||
|
|
|
||
|
|
Calling digitalWrite(RGB_BUILTIN, HIGH) will use hidden RGB driver.
|
||
|
|
|
||
|
|
RGBLedWrite demonstrates controll of each channel:

|
void neopixelWrite(uint8_t pin, uint8_t red_val, uint8_t green_val, uint8_t blue_val)
|
||
|

|

|
|
WARNING: After using digitalWrite to drive RGB LED it will be impossible to drive the same pin
|
||
|
|
with normal HIGH/LOW level
