Testing a infrared reflective sensor module<\/a>.<\/p>\n

I set it up with an arduino board, running the following sketch:<\/p>\n

\r\nint sensorPin = 10;\r\nint value = 0;\r\nint prevval =0;\r\nint count=0;\r\nvoid setup() {\r\n  pinMode(sensorPin,INPUT);\r\n  Serial.begin(9600);\r\n}\r\nvoid loop() {\r\n value = digitalRead(sensorPin);\r\n if(value==0 && prevval==1){ \/\/ something is dected\r\n   count++;\r\n }\r\n prevval=value;\r\n Serial.print(count);\r\n Serial.print(\"   \");\r\n Serial.println(value, DEC);\r\n delay(50);\r\n}\r\n<\/pre>\n
To run this, connect dout on the sensor to digital pin 10 on the arduino, connect + on the sensor to 5V and – to ground.
\nWhen the infrared light is reflected back to the detector, the output goes low. The sensitivity can be adjusted using the trim pot, turning it counter-clockwise lowers the sensitivity, i.e. what passes in front must come closer or be more reflective. In addition to watching the serial monitor for changes, there is a led that lights up when something is detected.<\/p>\n
