I'm not pushing the LED anywhere near an amp. The 2N2222 has a max Ic of 600mA, according the specs, but I'm limiting the base input to around 33mA with the 133ohm resistor in order to keep from overloading the Uno. So I'm guessing it is only putting out around 320mA or so to the LED. If I'm calculating correctly. But I don't have a spec sheet on the transistor, just the specs that were on the package.
I'll play with it when I get back Monday. You may be right, it may be frequency or something else. I'm not sure what range to expect from it though go be honest, this is all new to me.
I may have to switch to a MOSFET to power the LED to get the range I'm looking for. I really don't know. I need to research it a bit. I just assumed the transistor would be enough since I've seen TV remote designs for the Arduino that use them. Anyone know what the range to power ratio is approximately?
