[英]How to read multiple condition Python Arduino Uno
I have a question.我有个问题。 I am currently working on the python-Arduino Uno project.
我目前正在从事 python-Arduino Uno 项目。
so here we go.所以我们开始吧。 I wanna send the value from python 1 to Arduino and get the other value from python 2. so actually I want to make the Arduino Uno that can read 2 conditions then it will do stuff...
我想将值从 python 1 发送到 Arduino 并从 python 2 获取另一个值。所以实际上我想让 Arduino Uno 可以读取 2 个条件然后它会做一些事情......
code python 1代码蟒蛇1
i = results[1]
i *= 100
if i >= 75:
print('Recognised as Me!')
arduino.write(str.encode('1'))
else:
print('not matches')
arduino.write(str.encode('0'))
code python 2代码蟒蛇2
c = results[0]
c *= 100
d = results[2]
d *= 100
e = results[1]
e *= 100
for a in top_k:
if a == 0 and c >= 50:
arduino.write(str.encode('a'))
if a == 1 and e > 50:
arduino.write(str.encode('h'))
if a == 2 and d >= 50:
arduino.write(str.encode('s'))
Arduino code Arduino代码
int pin = 13;
char getValue;
void setup()
{
pinMode(pin, OUTPUT);
Serial.begin(9600);
}
void loop()
{
if(Serial.available() > 0)
getValue = Serial.read();
Serial.print(getValue);
if (getValue == '1' && getValue == 'h' ) { //its not works for me.
digitalWrite(pin, HIGH);
delay(1000);
}
else if (getValue == '0'){
digitalWrite(pin, LOW);
delay(1000);
}
}
You're only reading the value once, then comparing that same value twice.您只读取一次值,然后两次比较相同的值。 You need to read the value again using
Serial.read()
if you want to compare a second value.如果要比较第二个值,则需要使用
Serial.read()
再次读取该值。 A simple example of this:一个简单的例子:
value1 = Serial.read();
Serial.print(value1);
value2 = Serial.read();
Serial.print(value2);
if (value1 == '1' && value2 == 'h' ) {
digitalWrite(pin, HIGH);
delay(1000);
}
