Do you need to change the dirrection of the motor? If not, just use a MOSFET to drive it. Just Google "motor driver circuit"
92  Using Arduino / Project Guidance / Re: Help a newbie with an important decision! on: January 25, 2013, 04:26:03 am
Don't get the leo!!! It's SMD! That means if you destroy the chip it's pretty much irreplaceble! I got the expensive mega, and I've ruined it! And I can't replace the chip!

Hi all! I broke my Arduino and haven't yet got a new one, and I got really bored, so I decided to photograph some electronic components. Please enjoy!

If only you had a branch in Beijing... It sounds so awesome!

Do you live in Beijing?

The led on the servo, on the computer or on the Arduino? If it's on the Arduino, there's a short circuit and you must be very careful or you might destroy your Arduino.
97  Using Arduino / General Electronics / Re: im, running out of pins on: January 25, 2013, 12:42:20 am
You can make two ICs communicate with I2C, or you can use a shift register/driver IC
98  Using Arduino / General Electronics / Re: new to the arduino on: January 25, 2013, 12:39:47 am
I first learned with the book Getting started with Arduino by Massimo Banzi. Great book!
99  Using Arduino / General Electronics / Re: Arduino Mega, Screw (Terminal) it on: January 25, 2013, 12:35:17 am
You can solder your own screw shield, it won't be difficult.

101  Using Arduino / Motors, Mechanics, and Power / Re: Running a DC motor with PWM on: January 25, 2013, 12:17:46 am
This sounds like a nice project. What type of driver are you using? A driver IC, or MOSFETs, or a transistor circuit?
102  Using Arduino / Programming Questions / Re: Need some help for a science project. on: January 24, 2013, 11:59:05 pm
Aw... Sorry to hear that. Don't drop Arduino now you've picked it up though...
103  Topics / E-Textiles and Craft / Re: NEWB: wants to make shirt to monitor heart rate for cycling on: January 24, 2013, 06:46:14 am
Well, the Arduino Lilypad is specially designed to fit on clothing. You can get an SD-card shield.
104  Using Arduino / General Electronics / Re: Power supply building technical help required on: January 24, 2013, 05:56:18 am
I have a motor 12-24 volts, 2amps. My power suplys could only give about an amp, so I used two power suplies.
105  Using Arduino / Programming Questions / Re: Libraries in Arduino!!! on: January 24, 2013, 04:41:44 am
Do you mean servo libraries>?
