In this guide, you’ll learn how to control an RGB LED using the Arduino. An RGB (Red-Green-Blue) LED can produce a wide variety of colors by mixing different intensities of red, green, and blue light. You’ll learn to create a basic Arduino RGB LED circuit and cycle through some b...
See Arduino XOR Blinks LED. Line 4 " digitalWrite(LED1, temp);" will write the opposite or inverted latch value back to the LED1 latch. Let us look closer at lines 1-4. Line 2 could be rewritten as follows leaving out the need for line 3: byte temp = !digitalRead(LED1); One ...

Light-Emitting Diode (LED)(Most LEDs will work) Resistor(220 Ω) Arduino Blink LED Circuit To connect an LED to an Arduino, you need a resistor in series with the LED. This is to limit how much current the LED pulls out of the Arduino pin. The value isn’t crucial but should be ...
LED Green Pin -> 560 ohm resistor -> Arduino Pin 5 LED Blue Pin -> 560 ohm resistor -> Arduino Pin 6 Upload the ColorView sketch to your Arduino, then place different objects in front of the sensor. The LED color should match the color of the sensed object!
The rapid development of artificial intelligence and edge computing has led to new ways to create intelligent applications that process data directly on

which is the Adafruit brand name. Each pixel contains a WS2812 chip which communicates with the Arduino board and other pixels on its strip to determine whether to light up and what color–it can't light up without a controller. To control the strip, some additional Arduino funct...
