Hey Kind Folks!

I am using an Adafruit Simple RF M4 Receiver - 315MHz Momentary Type together with a four button key fob. I'm running the signal into a Feather and trying to use the fob to "jog" a motor in different directions. In other words, as long as I hold down a button the motor should run.

However what I'm experiecing is the motor is running in short "bursts" even though I'm holding the button on the key fob down continuously.

I put the output pin on the Simple RF M4 Receiver on an oscilliscope and I notice that even with the button pressed continuously, the output signal is "pulsing" between hi and ground at roughly 2 Hz.

Is this expected or is something going wrong? I was expecting that as long as I pressed the button down the signal from the receiver would be high.

Any suggestions here?

Thanks!

This sounds like the code driving the motor is not behaving as expected. The RF M4 pin will go high as long as a button is held. You can verify the voltage you are seeing across the pin while the button is pressed.

If you want to post your code we look at the motor logic.
