YK04 Controller Library

For Arduino boards.

The library implements a set of methods for working with a remote control sensors based on the YK04 driver.

The transmitter operates at a frequency of 315 MHz. It has four buttons, and therefore can control four loads. The board with a battery (23A, 12V) is placed in a convenient plastic case-keychain. It has a telescopic antenna, which will increase the range of signal transmission. There is protection against accidental pressing the buttons. It is realized with the help of a sliding cover.

Installation

1. Download the Latest release from GitHub.
2. Unzip and modify the Folder name to "YK04_Controller" (Remove the '-version')
3. Paste the modified folder on your Library folder (On your libraries folder inside Sketchbooks or Arduino software).
4. Restart the Arduino IDE.
