i decided to build a small handmade circuit that helps with detecting infrared light-emitting diode (IR LED) with low budget and as minimal components as possible.

It works with any kind of remotes in the world

It helps with discovering if the buttons on remote control are working fine or no

The range of the sensor is more than 5 meters

the size of the product is 3cm X 3cm X 2cm which allow to put it anywhere
