  Great. I'll give that a go. Thanks.

  Hi. Is it possible to do the WS2811 tutorials with a Puck? This page https://www.espruino.com/WS2811 says "the only condition is that the data wire is connected to an SPI MOSI port on the Espruino Board". Does the Puck have those?

  I tried connecting it up using a separate 5v power source, but nothing happened when I ran the code.

  Thanks,

  Jonathan

  Hey. Thanks. I didn't know about the built-in pull-down resistors. I've given that a go.

  I found this page with a load of information.

  http://henrysbench.capnfatz.com/henrys-bench/arduino-sensors-and-input/arduino-hc-sr501-motion-sensor-tutorial/

  It says "the device requires nearly a minute to initialize". So that may have been part of the problem.

  I think it's working now. Thanks.

  Hi. I'm trying to read from a PIR sensor. I'm aware that the sensor requires 5V, so I'm using a separate power supply for now. The problem is that as soon as I switch connect the power, the signal constantly detected by the pin. Even if I just touch a screwdriver to the pin, instead of using the sensor, a signal is detected.

  Am I doing something wrong?

  setWatch(function() {
    console.log("Movement detected");
  }, D1, {repeat:true, edge:"rising"});
  

  Thanks.

  @Gordon I only had to re-enable that flag and it started working again.

  Urgh. That's annoying. I did an update on Ubuntu and Web Bluetooth was no longer enabled.
