  Sorry for my late answer,
  I have tried all of the things you listed above and now I can set the BH1750 up correctly but if I try to use it, it still gives me an error, so i made a picture of my setup. Maybe you can find the problem with it.
  Heres the code:

  I2C1.setup({scl:B6, sda:B7});
  var bh=require("BH1750").connect(I2C1, 0);
  bh.start(2, 0);
  
  function lux() { 
    var luxx = bh.read();
    console.log("lux=", luxx);
  }
  
  setInterval(lux,1000);
  

  And here is the error message:

  Uncaught InternalError: Timeout on I2C Read BUSY
   at line 1 col 53
  ...is.i2c.readFrom(this.i2ca,2),a=(a[0]<­<8)+a[1];this.onetime&&...
                                 ^
  in function "read" called from line 2 col 22
    var luxx = bh.read();
                        ^
  in function called from system

  Ive recently tried to add the the Light Sensor BH1750 to the Pico but it doesnt seem to work regardless of what I try. I had already done this with my normal Espruino and it worked there.
  Heres how I tried to set it up :

  I2C1.setup({scl:B6, sda:B7});
  var bh=require("BH1750").connect(I2C1, 0);
  

  And thats the error message I get:

  Uncaught InternalError: Timeout on I2C Write BUSY
   at line 1 col 45
  ...i2ca=b;this.i2c.writeTo(b,1);this.i2c­.writeTo(b,3);this.acti...
                                 ^

  {return b?new c(a,92):new c(a,35)}
                                   ^
  in function "connect" called from line 1 col 41
  var bh=require("BH1750").connect(I2C1, 0);
                                           ^
  

  I have no Idea what I did wrong, so im looking forward to a newbee friendly answer.
