Learning Colors Using Arduino

This project is to help children who aged 2-4 years old.

There will be three different colors of LED, and when you press the bottom, one random LED will light up.

For more advanced, if you want your children to learn more, you can press the bottom 3~5 seconds without moving your hands, and also 2 random colors of LEDs will light up, and your children have to answer what is the color of 2 LED light up be like. For example, if the LED lighted up blue and red, your children have to answer ' purple'.

void setup(){ // put your setup code here, to run once:

pinMode( 2 , INPUT); // sets the digital pin as input

pinMode( 12 , OUTPUT); // sets the digital pin as output

pinMode( 11 , OUTPUT); // sets the digital pin as output

pinMode( 3 , INPUT); // sets the digital pin as input

pinMode( 10 , OUTPUT); // sets the digital pin as output

pinMode( 9 , OUTPUT); // sets the digital pin as output

}

void loop(){ // put your main code here, to run repeatedly:

if (digitalRead( 2 )) {

digitalWrite( 12 , HIGH ); // sets the digital pin on/off

digitalWrite( 11 , LOW ); // sets the digital pin on/off

}

else {

digitalWrite( 10 , LOW ); // sets the digital pin on/off

digitalWrite( 9 , HIGH ); // sets the digital pin on/off

}
