Lesson 101-5: How to Control a Servo Motor Using a Remote Control with Arduino
413-Lesson 101: Controlling AC Bulbs, TVs, DC Motors, and Servo Motors Using Arduino
语言: C++
/*
* Original library from - http://arcfn.com
* Lesson 101 code 5
* This Arduino code controls a servo motor with an IR remote controller or any TV remote.
*
* You have to select the type of your remote as Black or White in the code below
* and also select your receiver 1838 as either a PCB or bare module. See video for details.
