Blinking LED row
Blinking LED row
This is an arduino controlled project and uses leds, jumper wires, and a breadboard. This is one of my first attempts on programming arduino and I am pleased with the outcome. I'm ten years old and I just started programming 2 weeks ago.

This is simple wiring, and all you do is connect each negative terminal to itself and then to the arduino and each positive terminal to a positive pin on the arduino. Remember to connect them in order, ie. the first LED to pin #1 on the arduino and the second LED to pin #2.

This is the arduino code that I wrote.

#define LED01 13 // says led is at # 13
#define LED02 12
#define LED03 11
#define LED04 10
#define LED05 9
#define LED06 8
#define LED07 7
#define LED08 6
#define LED09 5
#define LED10 4
#define LED11 3

void setup()
{
pinMode(LED01, OUTPUT); // digital pin is output
pinMode(LED02, OUTPUT); // digital pin is output
pinMode(LED03, OUTPUT); // digital pin is output
pinMode(LED04, OUTPUT); // digital pin is output
pinMode(LED05, OUTPUT); // digital pin is output
pinMode(LED06, OUTPUT); // digital pin is output
pinMode(LED07, OUTPUT); // digital pin is output
pinMode(LED08, OUTPUT); // digital pin is output
pinMode(LED09, OUTPUT); // digital pin is output
pinMode(LED10, OUTPUT); // digital pin is output
pinMode(LED11, OUTPUT); // digital pin is output

}
