IR LED

An IR LED (infrared light emitting diode) is a solid state lighting (SSL) device that emits light in the infrared range of the electromagnetic radiation spectrum. IR LEDs allow for cheap, efficient production of infrared light, which is electromagnetic radiation in the 700 nm to 1mm range. IR LEDs are useful in a number of types of electronics, including many types of remote controls for televisions and other electronics. Used with infrared cameras, IR LEDs can act like a spot light while remaining invisible to the naked eye.

Infrared TV Remote Using ESP32(with Android App)

“The remote control from my TV was worn out and beginning to malfunction. As it was an older model, a new remote could not be purchased. So, instead, I decided to make my own TV remote to replace it. In …

IR Based Line Following Robot From Scratch (No Microcontroller)

“In this instructable we’ll use the concept, reflection of infrared radiation to built a circuit which can detect the difference between black and white coloured surface. That might not sound interesting but later we can use that circuit to …

Planck Constant Apparatus and Calculations

“Planck constant (h) is one of the fundamental physics constants and the most important constant in quantum mechanics. When I was studying physics years ago, I fall in love with Quantum Mechanics and now I have decided to conduct simple …

Do you want a luxurious IR laser measuring scale?

“Today, I will show you a “long-distance” and “high-precision” self-made high-standard measuring scale. High-end applications only require the best-quality ingredients and the simplest production methods. I have been busy for a few hours… Go ahead! Let’s see it. Step1 …

How to Make a IR Proximity Sensor at Home

“In this Instructable I show you how to make a simple infrared sensor for hobby projects and to learn how an infrared sensor works. I used an infrared sensor with one of my previous Instructables (the automatic hand sanitizer dispenser …

TinyTacho - Simple RPM-Meter based on ATtiny13A

“Recently Great Scott built his DIY version of a tachometer which I thought was very cool. But using an ATmega for this job, I found a bit overpowered. So I tried to force all tasks (measurement, calculation, I²C protocol and …
