Hello, I have an Arduino Uno and I am new to all this. What I am looking to do is control as many LED's as I can (14-20) in many ways. Such as: 2 Led's to flash back and fourth. 4 Led's to flash one after another. Some to flash randomly. Some
int led=2; int brightness=0; int fadeamount=5; voidsetup(){ //initialize digital pin as output pinMode(13,OUTPUT); pinMode(14,OUTPUT); pinMode(15,OUTPUT); pinMode(16,OUTPUT); pinMode(12,OUTPUT); pinMode(11,OUTPUT); pinMode(10,OUTPUT); pinMode(9,OUTPUT); pinMode(8,OUTPUT); pinMode(7,OUTPUT); pinMode(6,OUTPUT); pinMode(5,OUTPUT); pinMode(4,OUTPUT); pinMode(3,OUTPUT); pinMode(led,OUTPUT); voidloop(){ digitalWrite(13, HIGH); delay(400); digitalWrite(13, LOW);// turn the LED off by making the voltage LOW digitalWrite(12, HIGH);//here I am using Led's 13 and 12 to flash back and fourth delay(400); digitalWrite(12, LOW);// wait for a second delay(400); digitalWrite(11, HIGH); //here I am using Led's 11,10 and 9,8 to flash one after another. delay(400); digitalWrite(11, LOW); digitalWrite(10, HIGH); delay(500); digitalWrite(10, LOW); digitalWrite(9, HIGH); delay(500); digitalWrite(9, LOW); digitalWrite(8, HIGH); delay(500); digitalWrite(8, LOW); digitalWrite(7, HIGH); digitalWrite(6, HIGH); //here I am using Led's 6 and 7 to flash randomly delay(500); digitalWrite(7, LOW); digitalWrite(6, LOW); digitalWrite(14, HIGH); //here I am using Led's 14,15 and 16 to move right to left delay(500); digitalWrite(14, LOW); digitalWrite(15, HIGH); delay(500); digitalWrite(15, LOW); digitalWrite(16, HIGH); delay(300); digitalWrite(16, LOW); digitalWrite(15, HIGH); delay(500); digitalWrite(15, LOW); digitalWrite(14, HIGH); delay(500); digitalWrite(14, LOW); } }
Hello,I am sure if you check the adafruit or sparkfun store goto the learning center or check Arduino playground you will find the code to do what you want to do,the main thing is to learn to code using c and the Arduino ide,then you can build one step at a time,also you can download the Arduino book for free....I have 4 of them and use the to run my CNC and my pen plotter as well as various other indescribable machines .....WCH
