I want to create a mobile solution, that is, not connected with an adapter to the mains. I've tried a standard 9v battery, and to my amazements the battery is drained in less than an hour using only a 'blink' sketch. So my solution obviously requires more power, but how can I measure how much I will need? I'm thinking of connecting an adapter, connect the adapter to the Vin, and measure the amps drawn with a multi-meter. Also, the neo is running the 'full' neo distribution. Would power usage be reduced if I'd use the minimal?
