The keyestudio Multi-purpose shield V2 has 6 leds, in this example we will flash the LEDs The LEDs are connected to pins D8 to D13 Code [codesyntax lang="cpp"] //pin definition of LEDs int led1 = 13; int led2 = 12; int led3 = 11; int...
LED
This is just another simple app to control an RGB led, this time the app is a color picker Schematic Arduino Code [codesyntax.
In this example we connect an LDR to analog 0 and depending on the value read in we then vary the brightness of an LED connected to Pin 9 using.
This example requires an ethernet shield and an LED connected to pin 6. Copy the code into a new sketch and upload it to your arduino and then open your web browser to http://192.168.1.177 Code [c] #include <SPI.h> #include <Ethernet.h> #include <Servo.h> Servo myservo; ...
Connect an LED to digital pin 3 Code [c] void setup() { pinMode(3, OUTPUT); } void loop() { for (int a = 0 ; a < 256 ; a++) {.
The ability to flash an LED is the most basic 'hello world' type of program you can write and run on your arduino. Most Arduino's have an LED attached to.
