以USB Uploader 上傳以下程式
完成後再換成藍牙板(移除Jumper)

#define led 6
int inB;
void setup() {

Serial.begin(115200);

digitalWrite(led,LOW);
}

void loop() {

if (Serial.available() > 0) {

使用語音控制輪型機器人(App Inventor 2)

svg

//注意 LCD Address
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
byte inB;
LiquidCrystal_I2C lcd(0x3F,16,2);
void setup(){
lcd.init();
Serial.begin(115200);
lcd.backlight();

}

void loop(){
if (Serial.available() > 0) {
     inB = Serial.read();
   lcd.clear();
     lcd.setCursor(0,0);
     lcd.print(inB) ;
     lcd.setCursor(8,0);
     lcd.print(char(inB));
     lcd.setCursor(0,1);
     lcd.write(inB) ;
   }
}

ASCII Code

void setup()
{
Serial.begin(9600);
}
void loop()
{
Serial.write(0x48); // H
Serial.write(0x65); // e
Serial.write(0x6C); // l
Serial.write(0x6C); // l
Serial.write(0x6F); // o
Serial.write(0x21); // !
Serial.write(0x0A); // \n 換行
delay(1000);
}

顯示器:
如 Serial Monitor , LCD
一律將收到的8位元之二進位以ASCII 之字元顯示

The write() command sends a raw byte across the serial line.
print(), on the other hand, will try and interpret the number and send the ASCII-encoded version of that number.
For example, Serial.print(72) would print '7' '2' in the console.

參考:
print( )
write()

使用Serial.write() 與Serial.read()傳送2 Byte data

send the 16-bit value as two 8-bit values
Serial.write(0xCC);//send the start byte
Serial.write(sensorVal>>8 &0xff);//send the higher byte
Serial.write(sensorVal & 0xff);// send the lower byte

uint16_t data = 1000;
uint8_t buf[2];
buf[0] = data & 255;
buf[1] = (data >> 8) & 255;
Serial.write(buf, 2);

使用union

#define Led 12
union uData
{
byte b[2];
int value;
};
union uData data;
#define Led 8
void setup() {
pinMode(Led,OUTPUT);
digitalWrite(Led,0);
data.b[0]=0x34;
data.b[1]=0x12;
if(data.value==0x1234)
digitalWrite(Led,1);
}

void loop() {
}

2個Arduino
使用Serial.write() 與Serial.read()傳送2 Byte data

送端

nion uData
{
byte b[2];
int value;
};

union uData data;
void setup() {
Serial.begin(9600);
delay(1000);
}

void loop() {
data.value=0x3456;
//while(!(UCSR0A & (1<<UDRE0)));// 若UDRE0=0 等待
Serial.write(0x21);//起始字元
//while(!(UCSR0A & (1<<UDRE0)));// 若UDRE0=0 等待
Serial.write(data.b[0]);
// while(!(UCSR0A & (1<<UDRE0)));// 若UDRE0=0 等待
Serial.write(data.b[1]);
delay(1000);
}

或

union uData
{
byte b[2];
int value;
};

union uData data;
void setup() {
Serial.begin(9600);
delay(1000);
}

void loop() {
data.value=0x3456;
Serial.write(0x21);//起始字元
Serial.write(data.b,2);
delay(1000);
}

接收端

#define Led 12
union uData
{
byte b[2];
int value;
};

union uData data;

void setup() {
Serial.begin(9600);
pinMode(Led,OUTPUT);
digitalWrite(Led,1);
}

void loop() {
if(Serial.available()>0)
{
if(Serial.read()==0x21) //判斷是否為起始字元
{
   //delay(10);//若資料傳遞不正確可再加長
   // Wait until data is received (不用delay)
   while ( !(UCSR0A & (1 << RXC0)) ) ;
   data.b[0]=Serial.read();

//delay(10);//若資料傳遞不正確可再加長
// Wait until data is received (不用delay)
   while ( !(UCSR0A & (1 << RXC0)) ) ;
   data.b[1]=Serial.read();
   if(data.value==0x3456)
    { //Toggle D12
        digitalWrite(Led,1-digitalRead(Led));
      //asm("SBI 0x03,4");
    }
}

}
}

}
//loop() 無限迴圈區
void loop() {
    val=analogRead(irIn);
    if(val>500)
      digitalWrite(led1,LOW);
    else
      digitalWrite(led1,HIGH);
   if (Serial.available() > 0) {
     inB = Serial.read();
     if (inB=='1') digitalWrite(led,HIGH);//LED ON
