Sorry if I am being dumb but can anyone tell me why all the picaxe examples drive servo signals via a 330 ohm resistor and can it be omitted?
The reason I ask is I have seen other PIC hobbyists driving directly off the chip output.
I've knocked up a simple 3/4 servo controller based on the 08M proto board which works well. However, I had to bypass the 330 ohm resistor to get a triac to fire on the delay/duration timer I used it on. If I can omit the resistors from the design completely, it would simplify the board even further.
Cheers
