may 07, 2015 12:42:18	Arduino wattmeter	Not for the arduino i am using another signal conditioning circuit then i need negative Vcc for the op amp but i wanna use only one battery of 12 v how can i g ...
may 06, 2015 16:27:11	Arduino wattmeter	how to generate Vcc-(-12) using battery of 12V
apr 14, 2015 12:48:25	Arduino wattmeter	hi tugla, I am working on a project similar to yours So I advise you use current transformer that will transform the current from the line to 1A then after that ...
mar 11, 2015 00:10:48	Arduino wattmeter	so i ll use transformer of 240v/12v then after that i ll use the dividers as they are in the circuit above. what do u suggest to avoid harmonics?? knowing that ...
mar 10, 2015 19:00:55	Arduino wattmeter	thanks for those information . i have more questions. if instead of using voltage divider i ll use a potential transformer to step down the voltage, and a curre ...
mar 03, 2015 12:02:16	Arduino wattmeter	hi, in this circuit the range is + or - 50, how the voltage divider will be if i am using 220v and 32 A. and also the resistor R3 ?? thanks
mar 03, 2015 02:16:48	Arduino wattmeter	hi, zishan, i am working on the same project and i think that instead of using rf transmitter use GSM module it is programmable with arduino.
