Arduino IR remote and Software controller
https://www.electronics-lab.com/arduino-ir-remote-software-controller/
This is a DIY Infrared remote for speakers, replacing the original. Arduino Nano and controlled via a custom .NET application and placed in a laser cut enclosure. This one is an interesting one, it’s something we’ve been looking at for a while and figuring out how to solve it. We have sets of speakers and […]
Arduino Remote Control Tutorial
https://www.electronics-lab.com/arduino-remote-control-tutorial/
Øyvind Nydal Dahl show us how to use an IR remote control with Arduino. For this purpose he connects a TSOP312 and an IR LED to Arduino and goes in detail on the sketches. In this tutorial I am going to show you exactly how to make an Arduino remote control. You can use this […]
Arduino IR thermometer using the MLX90614 IR temperature sensor
https://www.electronics-lab.com/arduino-ir-thermometer-using-the-mlx90614-ir-temperature-sensor/
In this video we learn how to build a very usefull project. An Infrared thermometer, using the MLX90614 IR temperature sensor and the a Nokia 5110 LCD display shield. We are also using an Arduino Uno but you can use any Arduino board you like. Arduino IR thermometer using the MLX90614 IR temperature sensor – […]
Photoplethysmography – IR Heart Rate Monitor
https://www.electronics-lab.com/photoplethysmography-ir-heart-rate-monitor/
SteveQuinn @ instructables.com show us how to create a heart rate monitor using an IR phototransistor and Arduino and display the data on a TFT screen. This Instructable documents how to create a simple heart rate monitor using Photoplethysmography with an IR phototransistor via transmissive absorption using the Arduino to process the pulsatile data and display […]
Arduino IR Remote Control
https://www.electronics-lab.com/arduino-ir-remote-control/
theorycircuit @ instructables.com shows us how to use TSOP 1738 IR receiver with your Arduino Board. By using arduino and IR Receiver TSOP 1738 (in our project, you can use any ir receiver available) we can decode any infrared remote code into hex or some other format. Before constructing the circuit check datasheet of IR receiver […]
Non-Contact Body Temperature Meter
https://www.electronics-lab.com/non-contact-body-temperature-meter/
One of the most commonly used medical instruments nowadays is the thermometer. The thermometer is used to monitor or measure the body temperature of a sick person. The idea of creating a thermometer started from a device called thermoscope, a thermometer without a scale. Several inventors developed it until Sir Thomas Allbutt invented the first […]
Passive Infrared Detector Circuit
https://www.electronics-lab.com/passive-infrared-detector-circuit/
The infrared (IR) is invisible radiant energy, electromagnetic radiation that we cannot see with our eyes, but we can sometimes feel on our skin as heat. The infrared light falls just outside the visible spectrum, beyond the edge of what we can see as red. Most of the thermal radiation emitted by objects near room […]

Simple Infrared Barrier
https://www.electronics-lab.com/simple-infrared-barrier/
by Maurizio @ dev.emcelettronica.com: Although a remote control is not so difficult to design and build, there is an even simpler option: the IR barrier. This consists of a constant IR signal permanently going from an emitter to a receiver, both of them being in two different places (a few meters apart). When an obstacle comes […]
