I'm having difficulties reading any input from my RF module to my Arduino. I hope I have done all the necessary simple tests prior to asking for help here on whether or not the receiver is faulty.
There was a forum post over at Arduino with a similar problem, but unfortunately, no solution found.
- SC2262 transmitter and SC2272 receiver 433.92 MHz with keyfob TX, cheap off eBay.
- Arduino UNO R3
- Prototyped with standard breadboard and jumper wires. D0-VT to Arduino pins 2-6 respectively.
As suggested in the other forum post, I have used a meter to measure the voltage across GND to each digital PIN and see no flicker of life with each button press. This is the M4 sub-type which I understand as momentary, however, the meter is flat 0V which I don't believe would be expected.
There is demonstrable 5V on receiver module power pins.
Using an RTL-SDR dongle also demonstrates transmission peak on button press so I don't believe the fault lies at the transmitter end. New A23 battery in keyfob.
I haven't included any code here, as I don't think this is where the fault lies. I can demonstrate correct digital reads in Serial Monitor when artificially replicating signal with 5V.
In addition, I believe that there are encoder/decoder chips onboard this module. I did try adding a library from GitHub (QuentinCG's) but it made no difference.
This leads me to believe the receiver may have a fault. However given my lack of experience, it could equally be oversight of something simple.
If you want me to put up my code, or photos of the breadboard please let me know.
