Title: Electronic's Tutorial / Help
Post by: Bobsta on September 23, 2010, 07:40:44 PM

Hey guys,

I'm new to robotics but picking it up pretty fast  :D
I am currently waiting on the last of my parts to arrive for the $50 robot, so bugging to get started on that.. But while I wait I'm designing / planning what i'm going to build next..

I was wondering, are there any tutorials etc. on electronics / circuits I can read & learn, on what sort of capacitors/resistors/regulators etc. that you would need in a circuit for multiple Servo's & sensors ?

So example:

If I'm building say a quadruped robot and I have 3 Servo's per leg, how many resistors and what sort would I need for the project.

I'm just throwing Idea's around so any tutorials / information would be much appreciated !  :D

Cheers guys!

PS: Sorry if there is a topic already posted on the forum I haven't searched, if you could redirect me to it, that would be excellent.  ;)

Hi, Welcome to SoR! :)

You Wouldnt need any resistors for servos, just a connection to power (red wire), ground(black/brown), and signal(white/yellow/orange).  The signal wire goes to a PWM (http://www.societyofrobots.com/member_tutorials/node/228) capable pin on your microcontroller (Atmega8).

To get you started:

for general electronics: http://www.kpsec.freeuk.com/ (http://www.kpsec.freeuk.com/)
for modding a servo for continuous rotation: http://www.flickr.com/photos/randomskk/sets/72157605559564231/ (http://www.flickr.com/photos/randomskk/sets/72157605559564231/)
for general c programming: http://cprogramming.com/ (http://cprogramming.com/) or C primer plus 5th edition
for learning how to program a microcontroller: learn by reading example projects from other people and building them, then modding them and seeing what happens...best way to learn is by first hand experience.
where to get components/sensors/batteries/servos etc.: http://www.societyofrobots.com/robot_parts_list.shtml (http://www.societyofrobots.com/robot_parts_list.shtml)
for the many questions you will probably have: the forums (http://www.societyofrobots.com/robotforum/index.php)
and for when your in the mood to just chill, get to know some more of the members on the forum, and just talk about stuff: http://www.societyofrobots.com/robotforum/chat/ (http://www.societyofrobots.com/robotforum/chat/)

Hope you enjoy your stay!
