Post by: izaktj on October 25, 2008, 10:40:33 PM
Unanswered questions:
None ATM  ;)
----------------------------
Answered questions:
1- 28 Pin DIP socket, what is it's function? (Yes I searched before asking)
2- Is it the same if I connect the servos ground to the 9v battery ground or 5v(regulated) ground? (I'm using battery pack)
Thanks.

That's it?

all grounds should be connected together everywhere.
if you are using more than one battery pack in a circuit you will need to connect all grounds together.
your servo ground should definitely be connected to the GND on your 9v battery AND your 5v(regulated) GND.

i don't know the details of your circuit but 9V will be too much for your servos.
you will need to power then from a 5-6V source. (again make sure all the GNDs are tied together.)

Woot thanks mate!  ;D
I'm using a 6V for the servos and 9V regulated to 5V for the micro and digital inputs.

If you are going to use a 9v battery and regulate it to 5v you are gonna waste lot of energy and your regulator is going to emit a lot of heat.

I'm following the $50 robot tutorial  ???

you can use the 9V but I'm just saying that using 6V is more efficient.  ;)

Oh I see, yeah I understand. Thanks mate.
