Hi all! First post.
I have done some searching on the forums and I didn't find an answer that helped me too much. I have an IR LED and a 9V alkaline battery. The way I am testing how "on" the IR LED is, is by looking at it thru an old camera. I have tested the camera on a TV remote and there is a bright blueish light when I press a button. When I wire up the IR LED with the 9V battery and a 100Ω resistor, the IR LED barely lights up.
My question is: can a 9V alkaline battery push enough current to power the IR LED? Should I buy a 12V battery with a higher A/hr rating?
Thank you guys for the help.
