1  Using Arduino / Installation & Troubleshooting / Arduino stops working when connected to an external power supply on: September 23, 2012, 02:04:58 pm
My Arduino works fine when its connected to the computer via the USB but as soon as I disconnect it from the computer, it goes off. I am using a 12V DC adapter (500mA) (center positive) as the external power source. Not sure what is wrong. Please help!
2  Using Arduino / Sensors / Trouble with the Arduino and 'PING' Ultrasonic Sensor on: September 23, 2012, 11:41:03 am
I would really appreciate it if someone could help me with this.
I have connected my Arduino to my computer... I set the ports and everything and tested it with the 'Blink' program... everything was fine... then I connected the 'PING' ultrasonic sensor to the Arduino (as shown in the PING tutorial) - a message flashed on my computer screen saying that the USB device was pulling too much power and thus, has been disabled, in order to protect the computer! ... so I connected the Arduino to a DC adapter, hoping this would help... but nothing...
PLease advice on what I could do to fix this! Thank you!

Thank you all for your support and encouragement! I have managed to complete constructing the actual puppet (hand-cut out of goat-skin parchment) - she is 7ft. tall! I am now in the process of troubleshooting the electronics and programming, to get this humongous thing to move!
The puppet was essentially going to be a marionette, but s I was looking for jerky, twisting movements, I decided to simplify the design and create a wooden brace and spine for it, which is attached to the motor, and spins left and right in response to audience movement, recognised byt the "ping' sensor.
If I manage to get all tis done in time, the puppet will be on view at the dumbo arts festival next weekend!
I'm stil really struggling with the Arduino and programming and such but hoping it will all work out!

I am a visual artist working mainly in video installation. I have recently begun making and including shadow puppets within these installations. In my latest work, I plan to construct a large, many-armed shadow puppet out of leather or parchment... I need this puppet to be mechanized, to react to the movement of the people in the space where it is displayed - more specifically, as a viewer approaches the puppet, I would like it to twitch and flay its arms, or turn its torso away from the viewer... depending on the position of the viewer, a different arm would move (the puppet has 8-10 arms)...
I am not sure where / how to begin... any suggestions / advice are most appreciated!!! In short, HELP!!!
(I am assuming that I need motion sensors, mechanisms to move the puppet, circuits, arduino... not sure how it all fits together... HELP!)
