Hello Group.
I'm running a small (.14 amp) fan via an NPN TIP 29 transistor. In testing the system, I've simply programmed the Picaxe 08M (Pin 1) to go high for 5 seconds, low for 5 seconds and then loop.
But I've noticed that Pin 1 produces the expected 5 volts at high but also produces .04 volts at low. The amperage is .03 amps at high and 0 amps at low. Should there be any voltage on the pin at Low??
Thanks.
