DIY AC Watt Meter
If you are looking to build a new project, this DIY AC Watt Meter would make for a useful device that can be added to your test bench. “The microcontroller of the wattmeter is PIC18F252. Basically it reads the voltage and the current and calculates the RMS voltage, the RMS current and the average power. Then it interfaces with the LCD and shows all these values. It has a
