I’ve had this 315 MHz RF transmitter and receiver (purchased from: eBay Page) for a while now and am struggling with how to use it. I want to be able to determine which button I push on the standalone remote, using the receiver module.
The receiver chip is marked SC2272-M4 and the transmitter in the remote control is SC2262. I found a datasheet that states that these do work together. The pins seem to all be in the same configuration (top row all soldered, bottom row all open). The transmitter board is marked XY-T4 and the receiver module is marked XY-DJM-5V.
I have looked at various RF module pages but I am still having trouble with getting this to work. Most RF module tutorials I have seen seem to use VirtualWire (which I do not think I can use because my transmitter is not placed on another Arduino) or RCSwitch (does not seem to support my RF chip according to documentation).
So far, I have tried reading from analog and digital but without any luck. Per the eBay description and one tutorial (although they were using a 2 channel system), I read the VT pin to determine if there was any input before looking at the channels. With analog, I get a pattern of values that does not seem to change when I push the remote. However, it is going quickly, so it is possible I just did not see any change. Is there a way to slow the Serial Monitor down? With digital, I keep getting a value of 1 printed to the Serial Monitor.
Am I doing any of this right? Should I be doing something else instead?
Attached are photos of the setup and module and remote.
