Mapping of Pins on the Dagu Spider Motor Controller

I made a mapping of the Dagu Spider Motor Controller pins. The cells in red are what you see on the board itself. Other info has been placed adjacent to those cells for easy reference of functions, alternate names etc.

 

Curiously I am wondering if there is actually a typo mistake on the board with one of the pins being labelled as "TXD1/D1" when it should be "TXD0/D1" instead. Is that an error?

 

Please give feedback on the accuracy of the mapping.

 

This is a current work in progress that is waiting for a few parts.    The goal for this project was to make a robot that could go after people with an airsoft … Read more

Biped Howto: Moving servos

+++ UPDATE (12-march-2014): Rename title as "Biped Howto".

Hi, I will try to explain, in a very simplistic manner, the way in which servo motors can be controlled.

Servo motors are controlled by a PWM signal, in which the active part of the signal (known as duty cycle) define the amount of degrees the servo will rotate.
