Output Devices

• Add an output device to a microcontroller board you've designed and program it to do something

Board Designing

I have decided to design a the Input and Output circut in one board. I chosed the Ultrasonic Sensor "HC-SR04" as Input to be used in measuring the distance and "RGB Led" as Output for emmiting beautiful colors.

First I started form Niel's boards hello.HC-SR04 and hello.RGB.45 , and I used Eagle to combine them

Machining and Soldering

Programming

This week I am focusing on the Onput part. I wrote a sketch to make the RGB blinking between "Red"-"Green"-"Blue" every 1 second.

                  int redPin = 0;
                  int greenPin = 1;
                  int bluePin = 2;

                  #define COMMON_ANODE
                  void setup()
                  {
                  pinMode(redPin, OUTPUT);
                  pinMode(greenPin, OUTPUT);
                  pinMode(bluePin, OUTPUT);
                  }
                  void loop()
                  {
                  setColor(255, 0, 0); // red
                  delay(1000);
                  setColor(0, 255, 0); // green
                  delay(1000);
                  setColor(0, 0, 255); // blue
                  delay(1000);
                ;
                  }
                  void setColor(int red, int green, int blue)
                  {
                  #ifdef COMMON_ANODE
                  red = 255 - red;
                  green = 255 - green;
                  blue = 255 - blue;
                  #endif
                  analogWrite(redPin, red);
                  analogWrite(greenPin, green);
                  analogWrite(bluePin, blue);
                  }
