Reflect and Blink with Arduino

const int analogInPin =  A2;  // Analog input pin that the potentiometer is attached to
int sensorValue = 0;        // value read from the pot
int outputValue = 0;        // value output to the PWM (analog out)

void setup() {
  pinMode(3, OUTPUT);
}

void loop() {
  // read the analog in value:
  sensorValue = analogRead(analogInPin);
  // map it to the range of the analog out:
  outputValue = map(sensorValue, 0, 1023, 0, 255);
  if(outputValue > 240){
    digitalWrite(3, LOW);
  }else{
    digitalWrite(3, HIGH);

Add Serial Port

Reference: ATtiny85 & ATtiny84 Analog Pins, Serial Communication, etc.

#include "SoftwareSerial.h"

const int analogInPin =  A2;  // Analog input pin that the potentiometer is attached to
int sensorValue = 0;        // value read from the pot
int outputValue = 0;        // value output to the PWM (analog out)

const int Rx = 1; // this is physical pin 7
const int Tx = 2; // this is physical pin 6
SoftwareSerial mySerial(Rx, Tx);

void setup() {
  pinMode(3, OUTPUT);
  pinMode(Rx, INPUT);
  pinMode(Tx, OUTPUT);
  mySerial.begin(115200); // send serial data at 9600 bits/sec
}

void loop() {
  // read the analog in value:
  sensorValue = analogRead(analogInPin);
  // map it to the range of the analog out:
  outputValue = map(sensorValue, 0, 1023, 0, 255);
  mySerial.print("sensorValue = ");
  mySerial.println(outputValue);


  if(outputValue > 240){
    digitalWrite(3, LOW);
  }else {
    digitalWrite(3, HIGH);
  }
  delay(10);
}

Test Results：

outputValue: 210~240

outputValue: 160~180

outputValue > 240

Fix the Bug when the outputValue < 180

#include "SoftwareSerial.h"

const int analogInPin =  A2;  // Analog input pin that the potentiometer is attached to
int sensorValue = 0;        // value read from the pot
int outputValue = 0;        // value output to the PWM (analog out)

const int Rx = 1; // this is physical pin 7
const int Tx = 2; // this is physical pin 6
SoftwareSerial mySerial(Rx, Tx);

void setup() {
  pinMode(3, OUTPUT);
  pinMode(Rx, INPUT);
  pinMode(Tx, OUTPUT);
  mySerial.begin(115200); // send serial data at 9600 bits/sec
}

void loop() {
  // read the analog in value:
  sensorValue = analogRead(analogInPin);
  // map it to the range of the analog out:
  outputValue = map(sensorValue, 0, 1023, 0, 255);
  mySerial.print("sensorValue = ");
  mySerial.println(outputValue);


  if(outputValue > 240 || outputValue < 180){
    digitalWrite(3, LOW);
  }else{
    digitalWrite(3, HIGH);
  }
  delay(10);
}
