Hello and My New Arduino Robot Project

Hi Guys,

This is my first post here although I have been lurking for a few weeks now. I am brand new to the world of robots and Arduino. I bought my first Arduino in September and I'm just starting my first robot! My robot's name is Herbert...named after H.G. Wells and kind of an homage to Star Trek....

I plan to have Herbert be a long term learning project. I'm starting with simple motor control and moving up and onward from there. Here is my first video documenting my learning about Arduino motor control using transistor circuits:

Salvaging components

Hello, I'm new to this site and to robotics, it looks like a great place to find knowledge and inspiration about robots so I signed in.

   I am currently waiting for an arduino board to start experimenting, so I am trying to salvage parts and componets from broken electronics (as much as possible)  to save some money. 

Arduino Contest

I hope this is the place to post this contest to within the forum. If not, just let me know.

Voltage regulator problem

Hi, i recently added a sharp ir sensor, a servo, and a picaxe 8m to my robot, trix. The power supply i made for the picaxe board and sharp ir sensor assembly was simple and should have worked i thought, it was a five volt regulator from parallax, a 9volt bettery clip, and a 3 pin header for the power out (5volt reg, un regulated 9v, ground), However when i plugged the power supply into the picaxe board, my multimeter read only like 2.5 volts across the picaxe and the voltage regulator heat sink got so hot i burt my finger quite a bit.

Need Help for AGV?

i'm working on AGV project rite now.low cost AGV.i'm totally dont have knowledge in software part that is programming part?especially to do the coding for the robot.but for hardware part is not a problem to me.can somebody help me with the coding part?i'm using atmel microcontroller and will attach with stepper motor.for sensor i'm using ultrasonic for obsctacels sensor.

arduino functions

Calculon is discovering the wonders of arduino programming, and he is confused with the function (subroutine) action. He defines and declares a function, but nothing happens. Behold the simplified code:

void loop(){

   goMotor;   //call the goMotor function

}

void goMotor(){    //activate dc motor via h-bridge

digitalWrite(4,HIGH);
digitalWrite(5,LOW);

}
