The line drawings are converted to coordinates, and sent to an Arduino, which controls all the motors that move the pen. [Niazangels] went with Dynamixel closed loop servo motors rather than the ...

Making a servo tester using an Attiny85 micro chip, Attiny45 also works for this project. This diy servo tester is as good as ...

Enrico shows how his Infineon TLE94112EL motor controller shield can be put to work through a simple Arduino sketch.

Pretty much every project I've done just lately has required me to test out some servos and experiment with their positions before they go into the assembly. I usually make a quick servo tester on ...

To do this in Arduino/C code, a new intermediate position for the servo is specified for each main loop until it reaches the final position.

10 Simple-But-Fun Projects to Make With Arduino John Boxall, author of the new book Arduino Workshop, shares a few of the projects from his book on how to get started with the microcontroller.
