Seeedstudio Buzzer Tutorial
Introduction
The purpose of this tutorial is to use the existing tutorials and incorporate the buzzer. Our goal was to make the buzzer "buzz" when the push button was pressed.
Overview
For this tutorial we used the Seeedstudio Electronic Brick Starter kit which includes various sensors, components, cables and a shield to help get you started with various Seeedstudio Arduino compatible microcontrollers.
Meat and Potatoes
We like to get straight to the point. Below you will find the same code used to work with the Buzzer. Take into account that this is a basic code example. We do not get into the all the details of how or why you would use a Buzzer. Merely, how to code for it.
Sample Code
#include
LiquidCrystal lcd( 10, 11, 12, 13, 14, 15, 16 );
int buttonPin = 8;
int buzzerPin = 9;
int val = 0;
void setup()
{
Serial.begin( 9600 );
lcd.begin( 16, 2 );
lcd.clear();
pinMode( buttonPin, INPUT );
pinMode( buzzerPin, OUTPUT );
}
void loop()
{
lcd.setCursor( 0, 0 );
val = digitalRead( buttonPin );
if( val == HIGH )
{
lcd.println( "button pressed " );
digitalWrite( buzzerPin, HIGH );
}
else if( val == LOW )
{
lcd.println( "nothing pressed " );
digitalWrite( buzzerPin, LOW );
}
else lcd.println( "unknown state" );
delay( 1000 );
lcd.clear();
}
