A brilliant free robot control software that lets you assemble services to add functionality.
Hey all! I'm so excited by my first experiences with MRL ( http://myrobotlab.org/ ) that I thought I might post a video that I just made. I am currently finishing … Read more
Controls servos by Angle Accurately
I have always seen things differently with my electronics and programming background. Servo Math came from me seeing servos as having three parts. The angles … Read more
Helps those who don't have access to a solder or doesn't have the correct jumper wire
Any people out there who don't have an access to a solder or don't know how to use one, doesn't have the correct jumper wire, etc., consider this cheap (actually … Read more
Expands PWM outputs for servo control
     Those who intend to build a more complex project (in this case I mean with more DOFs, like a hexapod, biped humanoid and others) may find dificulties if … Read more
Performs speech recognition and control a few LEDs. It can be used to speech control anything.
  In this project I connect my Arduino Board to a WiFly module (https://www.sparkfun.com/products/10822) from Roving Networks and stream audio to the PC, so that … Read more
