描述

大家好?。。g迎來(lái)到基于 Arduino 的新項(xiàng)目。我們一生中都玩過(guò)飛揚(yáng)的小鳥(niǎo)游戲。如果我們?cè)谖覀兊?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(shí)，您將使用微控制器控制游戲。

項(xiàng)目工作簡(jiǎn)介：

1 / 3

?

我們?cè)谶@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(lái)調(diào)整移動(dòng)的鳥(niǎo)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(qǐng)看一下它們以便對(duì)這個(gè)項(xiàng)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(gè)傳感器接口，我不會(huì)為這個(gè)項(xiàng)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(shí)候?qū)⒋a上傳到您的 Arduino 開(kāi)發(fā)板了。

從下面復(fù)制代碼。

在上傳代碼之前，請(qǐng)確保選擇正確的 com 端口和波特率，因?yàn)槲覀儗⑹褂盟蛴螒虬l(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(kāi)處理程序：

?

上傳 Arduino 代碼后，下載并打開(kāi)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。
