Temperature and light sensor

Ahh - yes, it's because you're mixing the two methods of communication - the simple Puck.write/eval and the more complicated connection one.

You have two choices really:

• just use the simple version (so add a Puck.eval("(Puck.light()", ...) to get the light level when you need it)
  

• Modify the connection version to print both the light and the temperature:

  connection.write("setInterval(function()­{Bluetooth.println([Puck.light(),E.getTe­mperature()]);},100);\n", ...
  

You could find other ways to work around it, but I'd say those are your easiest options
