Arduino两块板用红外传输数据怎么样抗干扰？

100fun

现在有两块Arduino板，想在两块板之间用红外传输数据。现在能传输到数据。但是如果旁边有红外线遥控器发送信号时就会收到受到干扰。请问怎么让才能解决。还有我想如果在两块Arduino传输数据的时候如果有物理阻碍导致无法接受信息，但是阻碍消失后数据还能继续传输。要怎么样才能实现？ 谢谢大侠帮助了～～ 这是我的Arduino代码。 bool transmitting_IR; bool receiving_IR; void turn_off_IR () { TCCR2A = 0; // Disconnect PWM TCCR2B = 0; // Stops the timer OCR2A = 0;  // No timer top digitalWrite(11, LOW);  // Ensure output is off transmitting_IR = false; } void turn_on_IR () { TCCR2A = _BV(WGM21) | _BV(COM2A0); // This mode toggles output once per timer cycle TCCR2B = _BV(CS20);   OCR2A = 210;  38 khz transmitting_IR = true; } bool detect_IR() { return receiving_IR = ! digitalRead(12); } void setup () { Serial.begin(9600); pinMode (11, OUTPUT); // IR LED pinMode (12, INPUT);  // IR receiver turn_off_IR();  // My helper function for controlling the IR LED detect_IR();    // Ensure the state is correct. } void loop () { detect_IR(); char ch; if(receiving_IR) ch = readch(); ch = Serial.read(); if(ch>0) sendch(ch); } unsigned long p=500; char readch() { char ch = 0; unsigned long start_time = micros(); while(micros() < start_time + p); for(int i = 0; i < 8; i++) { unsigned long bit_time = micros(); while(micros() < bit_time + 2*p); int result = detect_IR(); ch = ch | (result << i); } Serial.print(ch); } void sendch(char ch) { turn_on_IR(); unsigned long start_time = micros(); while(micros() < start_time + 2*p); for(int i = 0; i < 8; i++) { int result = (ch >> i) & 1; if(result == 1) { turn_on_IR(); unsigned long bit_time = micros(); while(micros() < bit_time + 2*p); } else { turn_off_IR(); unsigned long bit_time = micros(); while(micros() < bit_time + 2*p); } } turn_off_IR(); unsigned long end_time = micros(); while(micros() < end_time + 2*p); }

奈何col

本来调制到38K后就能抗一定干扰了,还有就是周围环境光不要太强....

距离近点，避免其他光 都可以
