Description:

Model No.: RF11A04 OR CE-RF11A-045V

1. Features:

Operating voltage: DC 3-5V

 

You can select different modes of operation with"M4 M3 M2 M1 M0" pad in the delay mode to adjust the delay time through an adjustable resistor.

 

In delay mode, the rotary variable resistor can adjust the delay time. Increase the time counterclockwise rotation, and clockwise rotation to shorten the time. Adjustable resistor is a precision resistor, adjust the time with a Phillips screwdriver to gently rotate (do not use excessive force)

Working Mode Description:

Self-locking: Press the remote control button, the IO port outputs high. Press the remote control button again, IO port outputs low.

Interlock: Press the remote control button D0, D0 IO port outputs high, other IO ports outputs low; remote control button is pressed D1, D1 IO port outputs high, other IO ports output low and so on.

Delay: Under Delay mode, there is a delay 0/1/2/3/4 five sub-patterns, by adjusting the variable resistor IO port high duration

4, the adapter remote control (learning remote control)

 

In normal operation mode, LED (D1) will be lit, when receiving a valid remote control (EV1527 / PT2262) key value, LED will flash.

Clean code: hold the button to press.LED offs, keep pressing about 8 seconds until LED lights. At that time, clean code completion (Note: After the implementation of clean code, previous remote controls do not exist.

Adaptation (learning):

Step 1 (into the learning mode):trigger the key button, LED offs;

NOTE: The process must be completed within 15 seconds

Control 12V Relay: See "RF11A04_4Relay demo"

 

 

 

Wiring

Screws were countersunk from the back of the acrylic. A wire was attached to each screw and then to a digital pin on the Arduino. When the wiper with the 5v wire touches the screw it pulls the digital pin high on the Arduino. Please see the schematic for further details.

Step 4: Program

Disclaimer: I am not a programmer and therefore the below code may not be the most efficient. Feel free to improve the code for your own uses if you see any errors or problems. It works for me so I hope it works for you.
