This is a library for an Arduino-compatible controller that interfaces with the Pololu QTR reflectance sensors.
For documentation, please see the user's guide for the library on Pololu's website.
- 3.1.0 (2018-08-08): Added support for dimmable QTR and QTRX sensors with separate control of odd/even emitter banks.
- 3.0.0 (2016-08-16): Updated library to work with the Arduino Library Manager.
- 2.1.2 (2015-12-03): Corrected
readLine()behavior to work with multiple instances (thanks to Tandy Carmichael). - 2.1.1 (2014-05-02): Minor improvements to
read()behavior and whitespace cleanup. - 2.1.0 (2013-04-18): Improved existing examples and added two new examples for printing raw values.
- 2.0.2 (2013-04-17): Made constructors initialize pointers to avoid possible problems.
- 2.0.1 (2012-09-13): Added a 200 us delay after emitter state changes to ensure sensors do not start being sampled before the LEDs turn on/off.
- 2.0.0 (2012-02-14): Initial release of library on GitHub (with Arduino 1.0 compatibility).
