IR infrared LED circuit diagram
The Infrared (IR) LED used
in a remote control is an application for an LEDdriver
... This application circuit
shown in figure 3 has been designed for a 9V ...
However, even with such improvement this schematic lacks
of stability. There is better approach to improve the design. We
can modulate IR
LED like shown
Shining the beam onto the photo- transistor lights the LED.
This is the expected result since the phototransistor responds
to both visible and IR,
as shown in Fig.
