Welcome to the Pololu Blog, where we provide updates about what we and our customers are doing and thinking about. This blog used to be Pololu president Jan Malášek’s Engage Your Brain blog; you can view just those posts here.
The Wixel Shield for Arduino that we released today represents a personal milestone because of what I did not do on it: the shield is the first electronic product made by Pololu that I did not design. That’s not to say I did not have some input on it or that other engineers here did not have substantial contributions to other products, but the Wixel Shield is a first because the basic product concept, the circuit design, and physical implementation (i.e. the PCB layout) were all done by someone else. We also just finished a big facility expansion that was taking up a lot of my attention this year, so I have some more time now to think about our design process and what it takes to go from a new idea to a finished product.

It is often desirable to control the speed and acceleration of hobby RC servos. Understanding your options can be confusing since there are various speeds involved, many similar terms are used, and the terms are not used consistently by different companies or end users. You might also have an idea of what you want your servo to do without knowing what to call it or how to describe it or how to implement it. To get a good understanding of what is going on, it is helpful to picture the position of your servo in relation to the commands you are sending it. A simple first attempt might look like this: Continued…
In this last article about generating pulses for hobby servo control, I will present what I think is the best solution to controlling many servos or controlling some servos while still leaving enough processing time to do other tasks. It’s not that easy to make this approach work well, so my recommendation in most cases is just to get one of our servo controllers, which use this technique. Continued…
