Arduino with 10 times CNY70 sensors

Other Hardware Sensors
1

hello guys,

I am bussy with an project where i have to read out 10 sensors(CNY70)
they just have to give a 1 are a 0.
it's already working, the sensors give a one when the sensor is 4,5V and a zero when my is sensor is about 0,6V.
*I use the digital inputs for this project.

  • the sensor works on 5V from arduino.
    here is a example how i do it with the sensors:

and then 10 times .
i already wrote this:

int D1 = 1;
int D2 = 2;
int D3 = 3;
int D4 = 4;
int D5 = 5;
int D6 = 6;
int D7 = 7;
int D8 = 8;
int D9 = 9;
int D10 = 10;
int D11 = 11;
int D12 = 12; // select the input pin for the Sensor

// variable to store the value coming from the sensor
int sensorValue1=0;int sensorValue2=0; int sensorValue3=0; int sensorValue4=0;int sensorValue5=0;int sensorValue6=0;int sensorValue7=0;int sensorValue8=0;int sensorValue9=0;int sensorValue10=0;

void setup() {
// declare the sensorpins as an input:
pinMode(D1, INPUT);pinMode(D2, INPUT);pinMode(D3, INPUT);pinMode(D4, INPUT);pinMode(D5, INPUT);pinMode(D6, INPUT);pinMode(D7, INPUT);pinMode(D8, INPUT);pinMode(D9, INPUT);pinMode(D10, INPUT);

Serial.begin(9600);
}

void loop() {

// read the value from the sensor:
sensorValue1=digitalRead(D1);sensorValue2=digitalRead(D2);sensorValue3=digitalRead(D3);sensorValue4=digitalRead(D4);sensorValue5=digitalRead(D5);sensorValue6=digitalRead(D6);sensorValue7=digitalRead(D7);sensorValue8=digitalRead(D8);sensorValue9=digitalRead(D9);sensorValue10=digitalRead(D10);
// turn the ledPin on

Serial.println ("D1"); Serial.println(sensorValue1);Serial.println ("D2"); Serial.println(sensorValue2);Serial.println ("D3"); Serial.println(sensorValue3); Serial.println ("D4"); Serial.println(sensorValue4);Serial.println ("D5"); Serial.println(sensorValue5);Serial.println ("D6"); Serial.println(sensorValue6);Serial.println ("D7"); Serial.println(sensorValue7);Serial.println ("D8"); Serial.println(sensorValue8);Serial.println ("D9"); Serial.println(sensorValue9);Serial.println ("D10"); Serial.println(sensorValue10);

delay (1500);
}
but i think it can be done easyer does somebody know a solution?
Thanks already!
(sorry for my english)

PS, if English is not your native language you better set it in your profile than other people will understand it directly,
By the way your English is not bad, visit the forum often and you will learn more than only Arduinese :wink:
