Controlling an LED with Arduino Using an IR Sensor An Infrared (IR) sensor is a commonly used device for proximity detection and object sensing. When combined with an Arduino and an LED, it can create ...

pinMode(IR_Pin, INPUT); // make the IR pin an INPUT: pinMode(GLED_Pin, OUTPUT); // make the LED pin an OUTPUT: pinMode(RLED_Pin, OUTPUT); // make the LED pin an input: ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

In this tutorial, we will learn to Guide you about how you can interface a heartbeat sensor with an Arduino to measure live-heartbeat of any person. We will be also interfacing an OLED display to the ...
