![]() The sensor’s effective distance range is 2 ~ 30cm. And the signal output interfaces a digital signal (a low-level signal). After a comparator circuit processing, the green light turns on. When the direction of an obstacle is detected (reflective surface), the receiving tube receives the infrared reflected. At a specific frequency, the transmitting tubes emit infrared. The sensor module is ambient light-adaptable, with a pair of infrared emitting and receiving tubes. SoftwareĪn IR sensor or infrared sensor is a type of electronic device that emits light in order to detect certain aspects of its surroundings.

The main aadvantages of IR sensors are their low power consumption, simple design and convenience. It can be used extensively in line follower obstacle avoidance robot, avoidance car, line count, tracking black and white lines, and many others. IR technology is used for various purposes in daily life as well as in industry. He is a self proclaimed total beginner to the world of programming.This project shows you how to automatically turn ON and OFF a Light using an Arduino with IR Sensor. Stephen Dearden is a retired Chemist, has been an electronics hobbyist for over 30 years and enjoys building models. wait for 30 milliseconds to see the dimming effect reverse the direction of the fading at the ends of the fade: change the brightness for next time through the loop: the loop routine runs over and over again forever: put your setup code here, to run once: the setup routine runs once when you press reset: ![]() Int fadeAmount = 5 // how many points to fade the LEDs by Int brightness = 0 // how bright the LEDs are ![]() Int led6 = 11 // the PWM pin the sixth LED is attached to Int led5 = 10 // the PWM pin the fifth LED is attached to Int led4 = 9 // the PWM pin the fourth LED is attached to Int led3 = 6 // the PWM pin the third LED is attached to Int led2 = 5 // the PWM pin the second LED is attached to Resistors, LEDs, stripboard How do you power your project?ĩ Volt Battery Arduino Code: int led1 = 3 // the PWM pin the first LED is attached to What type of Arduino board, Arduino clone, or Arduino compatible board does your project use?Īrduino Nano What components are used in your project? My challenge was learning the programming. I have already some experience with electronics. Looking back on this project, what can you say you have learned about programming and/or electronics through the creation process? ![]() Although a simple program, I am NO coder! Did the project end up as you expected?Įxactly as I wanted it to be, although the connections from the Nano board to some stripboard containing the resistors turned out to be very “fiddly” in what was a confined space. What was your biggest struggle as you worked through this project? The UFOs windows are green polystyrene and the whole effect gives it an eerie appeal! How does your project work?Īs you can see from the pictures and videos, the Arduino Nano controls the fade in/fade out behavior of six 3mm high intensity green LEDs. I wanted to start simple and chose a popular model kit: the Area 51 UFO model from Pegasus Models. With LEDs and LED strips getting smaller and smaller, some model makers are now incorporating lighting into their kits. I totally saw this above my house last night… Why did you build an LED lighting system for your plastic UFO model?īesides electronics, one of my other hobbies is building model kits. ![]()
