I'm in the process of transitioning from Arduino work to just using bare microcontrollers, and I've got a question that might be quite basic (but I've searched around and haven't found an answer for it yet).
I have an LED that I know should be quite bright when powered--and is when hooked up to an Arduino--but is very dim when hooked into an atmega328 pin. I'm powering the chip through the SparkFun Pocket AVR Programmer, and the LED is being powered through a resistor.
Is the voltage output from the atmega when powered by the programmer much lower than that of an Arduino? Am I doing something wrong?
