Try Multisim it's really cool, but it takes too much time to build a new part though.

Quick question about schematic drawings

Chris, I wonder which software you use to draw schematics because they look simple yet very nice and clean. For example, this one: http://www.pyroelectro.com/tutorials/l298_stepper/img/schematic_small.gif Did you manually draw both H-bridge and motor or the software already has it?

Hi Chris, What I mean by serializing and (de|un)serializing is that the way to convert all the data members' values into a string and transmit it, kind of like serialize() function in PHP. For example: <?php $obj = array('id' => 1, 'name' => 'led'); $str = serialize($obj); echo $str....

Web control for leds and motors

I'm trying to do a project to control leds and motors on the website. I plan to use XAMMP ( http://www.apachefriends.org/en/xampp.html ) for Apache, PHP, and MySQL because I have worked with PHP and MySQL before. I'm thinking about using struct for each object (led, motor) like this struct obj {...

I recommend you to use servo or stepper motors to move the arm because you would need a very complex closed loop feedback for your DC motors. :D

About the arms, I don't know but I'm pretty sure Chris would help you :P

Thanks for the info, I just order some PIC18 from Microchip but I'm still thinking of getting a good programmer board. Is there an universal board that can fit all pin sizes (4,14,16,28,40) for PIC MCUs?

Dang it, they charge a shipping fee for the H-Bridge driver sample now. Do you know a "free" alternative IC? :D
