Hi all, I am a newbie.
I am trying to drive a Lego Power Function IR Remote via an IR led using this library
My trouble is IR LED range: it works only at 10-15cm from LEGO IR Receiver.
The led is a TOOGOO 8 mm LED
850nm wave length
I am using a 100 ohm resistence (I tried up to 250 ohm).
I simply drive the led with an Arduino pin.
Where am I wrong?
Do I need to supply more power to the led?
