Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. Be sure to use the Arduino Stack Exchange for questions that are more Arduino and less robotics.

Can the rate of peristaltic pump's flow be accurate across changes in fluid viscosity?
The answers to "will it work" and "will viscosity affect flow rate" is really "it depends".
Peristaltic pumps that push air exist.
All pumps work by using low pressure to pull in fluid and high pr …

Controlling a 400W motor with 24V 16A batteries with an arduino board
$\frac{400\text{ Watts}}{24 \text{Volts}} = 16.666 \text{ Amps}$
So you want something that has an input voltage of 5V (for the arduino to be able to control it), and it should be rated for a 24+ Volt …

Arduino original or generic for a beginner?
If you're just starting out, you should probably use the original Arduino instead of a generic.
Let's say you follow an Arduino example using a generic, and things don't work the way you expect. … How will you know whether your Arduino code (or circuit) is the problem, and not the generic board?
In all actuality, a generic board will probably work fine. …

Why must I loop 127 times for a "7-bit" address in this example?
"7-bit" is like saying "7-digit", but implies base two instead of base ten. So, a 7-bit number can represent $2^7=128$ values in the same way that a "conventional" 7-digit number can represent $10^7= …

Sensors for differential drive
Typically, tracking the position and orientation of a vehicle is not accomplished by looking at the wheels — it's done with navigation sensors. If you were attempting to have closed-loop control (i.e …

How can I send video from my Arduino camera module video to my Android screen?
To answer the question "is it doable", I would say yes. There is apparently a product called Looxcie that does this, according to this review on Slashgear.
My guess is that it's using BlueTooth's Au …

Removing quadcopter drift to the side
The drift is being caused either by your position data being consistently wrong, or by your roll/pitch PIDs not correcting the drift error with their integral term.
In any case, it is the integral …

How to control an Arduino Board with wireless PS3 controler?
I don't have experience connecting a PS3 controller to an Arduino board, but if you can work out a computer-arduino connection then you can use PyGame to read the state of all the buttons and axes. …

What is the link between a quadcopter transmitter pulse and the roll/pitch/yaw angles?
The pulse you're talking about is pulse position modulation. Whether this is being used to set the throttle speed of each of your motors (separately), or to convey some other meaning to your flight c …

How to make a robot move using Arduino other than timing to predefined locations?
Without sensors or encoders, there is no way to know where you are. Without timing, there is no way to guess how far you may have travelled.
Without sensors, encoders, or timing, it is impossible to …
