Hi!
This I am sure it is a newbie question but here it goes...
I am doing a project where I need to send an IR signal. This part is done and the receiver it is getting it right...
But the problem is that it only works at a very small distance like 20cm...
After some search I found out that typically IR leds need more current than normal Leds so I have no resistor between vcc and the positive side of the led...
Still no luck....it got better but I want just a little bit more...
Searched again and I think I have to use some kind of transistor to get more current trough the led...
My VCC is only 3V and the most transistor I found to do this are 5V![Frown :( :(](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Can anyone help me with this??
Thanks
