Fun with RGB led in Arduino

fun with RGB led


RGB stands for Red,Green,Blue. RGB led there are three cathode and one common anode.Each cathode is connected to a single color(red,green,blue) .Different color are produce in a single led.

Today we are going to blink  led with the 3 different color serially.



Components Required

  • RGB led
  • computer
  • resister[330 ohms]
  • Cable connector

for this,first of all we need to arrange the hardware components


Open the arduino programming software and start programming

int red=13;// define the pins
int green=12;
int blue = 11;
Void Setup()
{ pinMode(red,OUTPUT);// initialized the output and input pins
pinMode(green,OUTPUT);
pinMode(blue,OUTPUT);
}
Void loop ()
{digitalWrite(13,HIGH);//red high for 50ns
delay(50);
digitalWrite(12,HIGH);//green high for 50ns
delay(50);
digitalWrite(11,HIGH);//blue high for 50ns
delay(50);
}
upload the program into Arduino using usb cable and enjoy with the output.

Multiple mcp23017 interfacing with Arduino

MCP23017 is the I/O port extender that runs on 12C. It is 16-bit I/O expender.in this tutorial we are going to interface the single and multiple  mcp23017 with arduino.  fig:- mcp32017 module IT has 16 I/O ports from PA0 to PA7 and PB0 to PB7. first of all we are going to interface the single mcp23017 with Arduino. For this  connect the circuit as shown on figure. Download the library for mcp23017  from  sketch-- include library -- manage libraries.
