T000140 Arduino

TinkerKit Rotary Potentiometer Overview A Potentiometer is a commonly used variable resistor. Turning the knob, you vary the output voltage between 0 and 5V. This value is sent through the middle pin of the pot. Output: This module outputs 5v when turned in one direction, and 0v when turned in the opposite way. When connected to an input on the Arduino using the TinkerKit Shield, you can expect to read values between 0 and 1023. Module Description: This module features a 4k7 Ohm linear potentiometer, a signal amplifier, the standard TinkerKit 3pin connector, a green LED that signals that the module is correctly powered and a yellow LED whose brightness changes according to the position of the potentiometer. This module is a SENSOR. The connector is an OUTPUT which must be connected to one of the INPUT connectors on the TinkerKit Shield. Code Example /* Analog input, analog output, serial output Reads an analog input pin, and T000140 Rotary Potetiometer Analog Sensor connected to I0, maps the result to a range from 0 to 255 and uses the result to set the pulsewidth modulation (PWM) on a T010111 LED Module connected on O0. Also prints the results to the serial monitor. created 29 Dec. 2008 Modified 4 Sep 2010 by Tom Igoe modified 7 dec 2010 by Davide Gomba This example code is in the public domain. */ define O0 11 define O1 10 define O2 9 define O3 6 define O4 5 define O5 3 define I0 A0 define I1 A1 define I2 A2 define I3 A3 define I4 A4 define I5 A5 // These constants won t change.
