這邊原本是傳送超音波的
那我現在要傳送三種資料
要怎麼把這幾行寫到上面的Data[0]~Data[2]
複製到上面去就可以了嗎?
if(Serial.available()>0)
{
val = Serial.read();
switch(val)
{
case 97: //測距離
for(int i = 0; i < 6; i++)
Serial.write(Date[ i]); //send packet to phone
break;
case 'f': // car forward
forward(0, 255);
break;
case 'd': // car backward
backward(0, 255);
break;
case 'l': // car turn left
left(0, 255);
break;
case 'r': // car turn right
right(0, 255);
break;
case 's': // car stop
motorstop(0, 0);
break;
}
}
}
void motorstop(byte flag, byte motorspeed)
{
digitalWrite( Motor_E1, motorspeed);
digitalWrite( Motor_E2, motorspeed);
}
void forward(byte flag, byte motorspeed)
{
digitalWrite( Motor_M1, HIGH);
digitalWrite( Motor_M2, HIGH);
analogWrite( Motor_E1, 200);
analogWrite( Motor_E2, 200);
}
void backward(byte flag, byte motorspeed)
{
digitalWrite( Motor_M1, LOW);
digitalWrite( Motor_M2, LOW);
analogWrite( Motor_E1, 200);
analogWrite( Motor_E2, 200);
}
void right(byte flag, byte motorspeed)
{
digitalWrite( Motor_M1, HIGH);
digitalWrite( Motor_M2, HIGH);
analogWrite( Motor_E1, 150);
analogWrite( Motor_E2, 0);
}
void left(byte flag, byte motorspeed)
{
digitalWrite( Motor_M1, HIGH);
digitalWrite( Motor_M2, HIGH);
analogWrite( Motor_E1, 0);
analogWrite( Motor_E2, 150);
}
我想再問一下紅色的三行 我應該要有嗎
//#include <Wire.h> 這行我查(1) I2C 地址設定 及 I2C 地址掃瞄是這樣
因為我編譯會再serialA=I2CBT.read();這行有錯誤
但是我當初傳送超音波沒有用到這幾行
但是我找範例傳送溫度資料他們是有那幾行
