I posted a question here not too long ago about a project I have that rotates a servo back and forth (http://www.picaxeforum.co.uk/showthread.php?t=8397). I just recently bought a few more parts to expand on it, which has now prompted further inquiry. In Manual 3, page 6,the “Standard Circuit 2” shows a circuit that connects a PICAXE to a Darlington IC which is then used to drive a motor. On page 18 of the same manual, the example described to connect a servo to a PICAXE states that, because of the noise produced, the power source for the servo and the power source for the PICAXE should be separate. Does this mean that a servo creates more noise than a cheap DC motor? I’m asking because I was hoping to use a single 7805 to supply 5V to both the servo and PICAXE and cannibalize my other 7805 for a second PICAXE/servo combination (the current setup I’m using has a two 7805’s – one for the PICAXE, the other for a cheap HiTec servo)
Thanks
