Bandwidth Usage In Forum

Just a little FYI. I have found that, because of the surveillance cameras being broadcast over the forum webpage, that I take a sizable hit on my available bandwidth. It's about 65K. With only about 300K or so (DSL) available to me in the first place, that is a sizable chunk. I like to park on the Forum page while pulling up the various threads in...

4 In 1 Orientation Sensor Or Inverted Pendulum Sensor?

Hi all, This may seem a dumb question to those with more experience so you'll have to excuse my naivety as I'm just starting out in the world of robotics.

Getservo() Explanation

So I wrote a code to assist in obstacle avoidance when I'm driving my robot, but it doesn't work, so I tried a couple of similar codes in a smaller version to find the culprit. Code #1 below only results in my sensor servo jittering. Code #2 works, but doesn't give me what I need, which is the exact location of the servo so I can know in what...

Rgb Animator

I have the "18 RGB LED PCB" from the DIY section of the store. It's easy to operate via the RGB Animator, but I would like to write a script to use on my mobile app. I've looked through the forum but can not find any code examples.
