Old infrared remote controls can be a great way to interface with your projects. One of [AnalysIR’s] latest blog posts goes over the simplest way to create an Arduino based IR receiver, making ...

A single seven-segment display might not be extremely useful, but with [firestorm]’s tutorial, it’s easy to give your Arduino some remote control capabilities with a simple IR receiver.

In my case I have used only 3 x 330Ω resistors, 3 leds and a TSOP4838 IR receiver module. You must check the datasheet before use the IR module to see which pins connect to the power supply and which ...

Each IR sensor has a transmitter (IR LED) and a receiver (Photodiode). When an object blocks the IR rays, the Arduino detects a voltage change and processes it as an event.

IR LED blaster and IR receiver for dogfighting mini quads. Generate 38KHz pulses using timer on either the arduino or the stm32f042 (soic stm32 chip), Take this and drive 1 or more mosfets with it, ...
