This improved infrared detector is specifically intended for use with commercial IR remote control handsets. This little circuit is useful for quick go/no-go testing of just about any remote control ...

If you are using infrared (IR) hardware in an IoT, embedded, or mobile hardware project and are currently experiencing difficulties debugging IR communications, using one of the circuits shown below ...

This infrared repeater system is used to extend the range of an infrared transmitter used at an audio or video equipment at 10 m. The original signal is captured by the infrared receiver (figure 1), ...

Infra-red (IR) remotes are great, unless you’re in a hackerspace that’s full of crazy blinking lights and random IR emissions of all kinds. Then, they’re just unreliable. Some smart folks at Metalab ...

Many robotic applications require a sensor to detect close or very close obstacles. Typically, reflective-type infrared sensors are used for this task. But the circuit in the figure shows an infrared ...

Together, these circuits simulate a digital closed-loop controller in Spice. Although this particular circuit was developed to simulate the digital infrared controller, its generic architecture may be ...
