用pwm控制小车电机，获取E18红外数据

电机程序：
[mw_shl_code=c,true]void setup() {
  // put your setup code here, to run once:
  pinMode(6, OUTPUT);
  pinMode(7, OUTPUT);
  pinMode(8, OUTPUT);
  pinMode(9, OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
  digitalWrite(6, HIGH);
  digitalWrite(7, LOW);
  digitalWrite(8, HIGH);
  digitalWrite(9, LOW);
  analogWrite(A0, 200);
  analogWrite(A1, 200);
}
[/mw_shl_code]
注：6789为数字IO口，A0A1为模拟IO口。

红外程序：
[mw_shl_code=c,true]int num = 0;
void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
}

void loop() {
  // put your main code here, to run repeatedly:
  num = analogRead(A3);
  if (num > 500)
    Serial.println("no people");
  else
    Serial.println("people");
  delay(100);
}[/mw_shl_code]

  analogWrite(A0, 200);
  analogWrite(A1, 200);
这两段是用来调速的吗

对，这个是用pwm波进行调速
