描述

大家好！！！歡迎來到基于 Arduino 的新項目。我們一生中都玩過飛揚的小鳥游戲。如果我們在我們的 PC 上播放它并使用我們的 Arduino 控制它怎么辦？按照下面給出的所有步驟操作，到本教程結(jié)束時，您將使用微控制器控制游戲。

項目工作簡介：

1 / 3

我們在這里使用超聲波傳感器的原因是為了獲取我們的手和傳感器之間的距離數(shù)據(jù)，并使用這些值來調(diào)整移動的鳥的高度。游戲在 Processing 中創(chuàng)建，Arduino 使用串行端口與其通信。我已經(jīng)鏈接了上面游戲的幾張圖片，所以請看一下它們以便對這個項目有所了解。

贊助商鏈接 - UTSource.net。

讓我們做連接：

?

首先將 SR-04 傳感器連接到 Arduino 板上。由于只有一個傳感器接口，我不會為這個項目添加電路圖。連接如下 -

SR-04 >> Arduino Uno

電源 >> 5V

接地 >> 接地

觸發(fā)針 >> 數(shù)字針 11

Echo Pin >> 數(shù)字引腳 10

就是這樣，連接就完成了。

上傳 Arduino 代碼：

?

現(xiàn)在是時候?qū)⒋a上傳到您的 Arduino 開發(fā)板了。

從下面復(fù)制代碼。

在上傳代碼之前，請確保選擇正確的 com 端口和波特率，因為我們將使用它向游戲發(fā)送數(shù)據(jù)。

const int trigPin=11;  //DECLARE TRIG PIN AT D11
int echoPin=10;         //DECLARE ECHO PIN AT D10
int safezone=10; 
void setup() 
{
pinMode(trigPin,OUTPUT);
pinMode(echoPin,INPUT);
Serial.begin(9600);
}
void loop()
{
long duration,cm;           //DECLARE VARIABLES TO STORE SENSOR O/P
digitalWrite(trigPin,LOW);  //MAKE THE TRIG PIN LOW
delayMicroseconds(2);       //WAIT FOR FEW MICROSECONDS
digitalWrite(trigPin,HIGH); //NOW SET THE TRIG PIN
delayMicroseconds(5);       //WAIT FOR FEW MICROSECONDS UNTIL THE TRIG PULSE IS SENT
digitalWrite(trigPin,LOW);  //MAKE THE TRIG PIN LOW AGAIN
duration=pulseIn(echoPin,HIGH); //MAKE ECHO PIN HIGH AND STORE THE BOUNCED PULSE IN VARIABLE DURATION
cm=microsecondsToCentimeters(duration); 
long inch= cm/2.54;
Serial.println(cm);
}
long microsecondsToCentimeters(long microseconds) //SPEED OF SOUND IS 29 uSEC PER CM
{
return microseconds/29/2;  //THE PULSE TRAVELS FROM THE SENSOR AND AGAIN COMES BACK SO WE DIVIDE IT BY 2 TO TAKE ONLY HALF OF THE TOTAL DISTANCE
}

打開處理程序：

?

上傳 Arduino 代碼后，下載并打開處理代碼。再次

設(shè)置與之前相同的波特率并提及正確的 com 端口。

現(xiàn)在讓我們來試試這個游戲。只需單擊處理IDE中的運行按鈕，然后

你已準備好出發(fā)。小鳥會根據(jù)你手之間的距離移動

和傳感器。如果您對此項目有任何疑問，請隨時發(fā)表評論
