    Arduino Nano built in RGB LEDs won't turn off

    OK. I finally actually read the comments in detail and my issue is the LED_BUILTIN is active HIGH and the RGB LEDs are active LOW. The White is all on. Mystery solved.... Thanks all! Kenny

    Arduino Nano built in RGB LEDs won't turn off

    I did.... Thanks... Here's Mine... /* Hook yo WiFi & Blinky */ #include <WiFi.h> const char* ssid = "WiFi Surveillance Van"; // Change this to your WiFi SSID const char* password = "KeepOffMyLan"; // Change this to your WiFi password int leds[] = { LED_BUILTIN, 14, 15, 16 }...

    Arduino Nano built in RGB LEDs won't turn off

    Well, after doing some more testing, I find if I turn on, say, the Blue LED and then turn it off, there is a background light of white(?) that stays on. Possibly for brightness? That is the light that doesn't turn off.... IDK...

    Arduino Nano built in RGB LEDs won't turn off

    I guess what might help is that I can't find the header files that define the values in cpp for the Arduino hardware. For instance, digitalWrite(LED2, LOW); I defined LED2 = 14; Actually I used an array... int leds[] = { LED_BUILTIN, 14, 15, 16 }; Where is LOW defined? Where is LED_BUILTIN...

    Arduino Nano built in RGB LEDs won't turn off

    Hello, Newbie here.. Trying to get used to using IO on my Nano. I can get the Orange LED to turn on and off, but the RGB LEDs will not shut off using digitalWrite(LED2, LOW); Probably an easy answer... Thanks in advance... Kenny

    Looking for a starting point for Micro-controllers...

    Hey all- I am an old geek/nerd and need some "learnin'" about how to start a simple project to make wifi/bluetooth things I can run remotely (IoT). Looking for a jump in spot. I have a raspberry pi to start with. I guess I'm looking for a place to start. Starting with test modules with a...
