This little circuit is invaluable for quick go/no-go testing of just about any remote control transmitting infra-red (IR) light. The tester is battery-powered, built from just a handful of commonly ...

We may receive a commission on purchases made from links. We've grown a little spoiled. At some point during the progression of televisions and media devices, remote controls went from infrared ...

You'd think a remote control technology that was first introduced in the 1980s would be completely obsolete by now. But infrared (IR) remotes are still very much kicking half a century later, despite ...

Over on his YouTube channel [Electronic Wizard] has released a video that explains how infrared (IR) remote controllers work: IR Remote Controllers protocol: 101 to advanced. This video covers the NEC ...

What is an IR Blaster and How Does it Work? An IR blaster is a hardware component in some smartphones that allows the device to emulate an infrared remote control, enabling it to control various ...

This circuit is the result of my research. I have used a photodiode, SFH2030 as an infra red sensor. A MOSFET opamp, CA3140 is used in the differential mode to amplify the pulses of current from the ...
