Also, what changes should I do in the code for me to detect only black color objects which will be placed at a small distance (~2cm-3cm) from the led pair.Again I will be excited if you reply as soon as possible!
Can it detect black color?If it detects black color, then how do I differentiate between white and black color?Also, what are the changes to be done in the code if I am using only one transmitter?I will be very excited if you reply as soon as possible!

hi i want to track any valuble devices like keys or etc . i want to add that sensor that device like key or etc . so that i can check how much far from me . In this scenario will it be helpful for me . i have seen that it detects height of a object from the top . but i need sensor which can tell how much distance far from me. can u tell me which device will be help ful for my project.
quick question, how do i change the rate that it dims at, because i need to be faster
Hey, has anyone figured out a code utilizing this concept but with a temperature sensor to change the color of the LED with body temp? Preferably adnafie's code listed below in the comments. Thanks!
Hey! i'm doing this for my graduation project (including other work) .i want a signal only if a specific distance is mesured (distance detector) for example if a small car is standing below it will be 2 meters far from it .. if a big car is standing below and the detector gets less then 1.2 meters it will give a signal so the car can't get in pleeaaaase i need help replay as soon as u can
Hi I would like to ask if you used any pwm functions for the LEDs as usually that is required when working with LEDs

No schematic ?
Works great! Thanks for the tutorial
Hi Ricardouvina, For the receiver, is there a difference if i used the dome shaped one with 3 legs rather than your 2 leg ones? also I tried using ur program but only when i changed the delay=100 for emitter=low, would the result be stable. Otherwise the result would be just a jumpy mess. But it wouldnt be logical since it would most of the time be reading the environmental infrared radiation? Sorry for the messy explanation. if u need more details to the problem please inbox me. Thanks in advance!
Also, im not using a buzzer. Im trying to extract out the distance for my project use.
