Light Equalizer by Ana Lucia Martinez Arias Demonstrates how to connect and use a SHARP GP2D12 or GP2D120 infrared ranger sensor. Interprets distance from the ranger sensor value turning ON a number of LEDs accordingly. The LEDs are connected to digital pins 0 to 9 int distance=0; void turn_all_off() { // function to turn off all the lights for(int i = 0; i < 10; i++) //LEDs connected to digital pins 0-9 { digitalWrite(i, LOW); } } void setup(){ Serial.begin(9600); // set the serial port to 9600 for (int i=0; i<10; i++){ pinMode(i, OUTPUT); // set pins 0-9 as outputs } } void loop(){ turn_all_off(); // turns all lights off distance = analogRead(0); // sensor connected to analog pin 0 Serial.println(distance, DEC); // prints the value read from the sensor if(distance>50){ digitalWrite(0, HIGH); // sets the current light on } if(distance>100){ digitalWrite(1, HIGH); // sets the current light on } if(distance>150){ digitalWrite(2, HIGH); // sets the current light on } if(distance>200){ digitalWrite(3, HIGH); // sets the current light on } if(distance>250){ digitalWrite(4, HIGH); // sets the current light on } if(distance>300){ digitalWrite(5, HIGH); // sets the current light on } if(distance>350){ digitalWrite(6, HIGH); // sets the current light on } if(distance>400){ digitalWrite(7, HIGH); // sets the current light on } if(distance>450){ digitalWrite(8, HIGH); // sets the current light on } if(distance>500){ digitalWrite(9, HIGH); // sets the current light on } delay(50); } Wiring is an open project initiated by Hernando Barragán. It is developed by a small team of volunteers. © Info, Processing © Info
