    Using arduino, I had unstable outputs when using the “5V” pin as the power supply pin and the pull-up for the alarm pin.
    Eventually, I used the “5V” pin solely for pull-up (i.e. resistor between “5V” of arduino and alarm pin (black) of motion sensor).
    To power the motion sensor, I tried using a 9V battery which works perfectly. I also tested using the “Vin” pin on arduino and can report stable output, although the detection is somewhat slower than using a pure 9V power supply. The “Vin” pin gives me 4.16V so I am not sure what is happening here.
    So the final pinout is:
    - “Vin” on arduino to Vin for sensor
    - “Gnd” to “Gnd"
    - Resistor between "5V” of arduino and alarm pin of sensor
    - Wire from alarm pin to input pin on arduino
    Hope this helps anyone trying to use this sensor with the arduino board.

  • News - SparkFun Gets a Cease and… | about 5 years ago

    This is the single, most absurd piece of litigation bs I have ever seen. I am familiar with SPARC and have been looking into its OpenSPARC platform and have never, even for a second, thought of SparkFun while reading about SPARC.
    This is plain stupid and I agree that the lawyers are the true winners in this. Do keep the SparkFun community posted on any updates and we’ll see how we can help out.

No public wish lists :(
