Hi! I have a problem with my newly bought receiver(MX-RM-5v), when I make a simple circuit with it, connected the data pins to a led, it always shows HIGH, when I send a HIGH with a transmitter it gets brighter, but as I interrupt the transmitter, it's showing again HIGH but not as bright as before.
I tried to connect to an Arduino, and write it out on the serial monitor, and it gets continuously a bunch of data. Any ideas ?
To send data with that type of setup, you need two Arduinos, a transmitter, receiver and a data encode/decode library like VirtualWire or RadioHead on each Arduino. Start by running the simple examples in the library.
There are plenty of getting started tutorials on the web, too.
This can not be used without any coding procedures?
No. The receiver just emits noise from the DATA pin, when not activated by a transmitter. Short transmission pulses are recognized, steady state transmissions are not.
