Ватт метр на базе ардуино и лсд дисплея 1602

For details DIY instruction please see my instructable : This energy meter uses 1. Simple voltage divider for sensing voltage 2. ACS 712 for current sensing 16x2 char for display BOARD SHIELD for uploading the data to I used a 6 volt lead acid battery for energy source and 3W led light load for simulation but in practical this energy meter can be used for measuring energy ,power,voltage and current of SOLAR P
