In theory the Arduino could directly drive the gate of the FET Q1 without using Q2 as a buffer; however this would result in approximately 500 µA of idle current constantly flowing through R4 into pin 7 while the system is turned. UPDATE: The Arduino Engineering Kit is the Bett Award winner for “Higher Education or Further Education Digital Services. The system was integrated with microcontroller and GSM network interface using arduino. PTS-Tech your Source for Measurement, Control and Power Equipment. My question is, is there any type of meter that I can attach to the generator to tell me how many watts that I am using. 0 w then its off at ~1500 w by about ~300. The Sensor Unit produces two voltages, one is the Voltage output from the power supply and another one is a voltage which ranges from 0 to 5V.
