Atn Function

Description

Returns the arctangent of a number.

Syntax

Atn(number)

The number argument can be any valid numeric expression.

Remarks

The Atn function takes the ratio of two sides of a right triangle (number) and returns the corresponding angle in radians. The ratio is the length of the side opposite the angle divided by the length of the side adjacent to the angle.
The range of the result is -pi/2 to pi/2 radians.
To convert degrees to radians, multiply degrees by pi/180. To convert radians to degrees, multiply radians by 180/pi.

Note Atn is the inverse trigonometric function of Tan, which takes an angle as its argument and returns the ratio of two sides of a right triangle. Do not confuse Atn with the cotangent, which is the simple inverse of a tangent (1/tangent).

Robotics nuts!

Check out http://users.frii.com/dlc/robotics/projects/botproj.htm from Dennis Clark. This guy ROCKS! He has made (and sells but also releases code, docs, etc...) for a number of cool little robotic modules including whiskers, IR proximity detect and remote control, Sonar proximity detect, PWM, Servo, compass. Most of these use the little PIC 12C508 controller which costs basically nothing and is soooo tiny.
The 4 servos, 2400 baud serial servo controller is a wonder of magic and he sells the programmed chip for $8. Wow!
