Picture of IR-Distance Sensor Homemade Tutorial
this instrument can detect precisely any object from a distance of 40 cm to 0.5 cm.
and this can actually calculate the distance of the object .
Here i will use this feature to analogWrite the LED.  which will incerease its brightness as the distance gets lesser ...

Step 1: The Circuit

Picture of The Circuit
You Can Build this with these Materials :-

-Arduino (Uno)
-Jumper Wires
-LED(Indicator ,any colour)
-IR LED Pair

You should follow The Schematict to make your own sensor then you may follow ahead ........

confused, because i thought the IR sensor outputs only low or high. How does it detect distance? thx

So, the sensor output value is a voltage in the range of 170 to 980, correct? is that millivolts? microamps?

The sensor output range will depend on your power supply, right?

i'm thinking you could take the Arduino out of the circuit, and drive the LED directly from the sensor, no? Maybe with a boost transistor.


Nice job!
