Ryan writes – “In robotics, there is always a need to control motors. One of the simplest source of mechanical power is a servo. However, if you’ve ever programmed a microcontroller to run a servo, you probably know that anything beyond a couple channels is not the most trivial thing to do. Doing it on a breadboard is even worse. To change all that I decided to design and build a printed circuit board capable of running 16 standard R/C car servos or speed controls. I think it turned out rather well, I added some buttons and LEDs to make it pretty and it all runs off a 7.2V R/C battery. The reason for staying with R/C components is they are relatively cheap and there is a decent variety of parts. After routing, soldering, and programming the board, I tested it out by attaching 6 servos to the bottom of a carboard box and hooking them to the first 6 channels of the board.” [via] – Link.
