Puck Lite GetBattery error

Hi,

Sorry for the delay. The issue is you're running that command in the web browser, and not on the Puck itself.

For instance to set the LED you do Puck.write("digitalWrite(LED1,1);\n"); not just digitalWrite(LED1,1);

So what you need is:

Puck.eval("Puck.getBatteryPercentage()", function(value) {
  console.log(value);
});
