Download [2.29MB]This project is a power meter (Wattmeter).
It is made for 230V~ (nominal, rms), 2.5A~ (max, rms) and 50Hz, but is rather easily adaptable to other voltages, currents and frequencies. It can handle both sinusoidal and non sinusoidal voltages and currents, both with and without DC component.

Download [595.37KB]Log ADC Values when button is pressed in internal EEPROM
RD0 - Start Log
RD1 - Erase complete EEPROM
LCD shows current ADC steps and voltage in 0-5V range.
Each time when RD0 is pressed uC take 8 samples from ADC in intervals of 3sec and stop.
PortC LEDs shows progress of sampling each byte in EEPROM like bargraph.
