An inexpensive RF wireless LED controller is easily adaptable to a controller for Arduino projects.
I opened it and found out what was the signal pin.
From the signal pin is a connection to the input pin of the arduino.
That was really all.
I removed the MOSFET and the processor from the PCB, because I did not need them.
The current at 5 volts went from 4,15 mA back to 3,63 mA which I also measure with another type of 433 Mhz receiver.
This remote control has 11 buttons and outputs 12 different codes.
The SPEED - and SPEED + buttons together give the 12th code.
Several remote controls of the same type produce different series of code.
See the photos and test with the ReceiveDemo_Simple.ino for more clarity.
