Figure 3: Arduino Wattmeter Full Circuit Diagrar this is my graduation design project I want to you to solve this circuit voltage and current calibration calculations and show me how you did ? MATERIALS AND METHODS 2.1. Voltage and Current Sensing Circuits Voltage Sensing: A 220:12 step-down transformer is used to reduce the AC mains voltage to a safe level. Voltage dividers are used to scale the voltage to a range compatible with Arduino's ADC (0–5V). Current Sensing: A Current Transformer (CT) is employed to measure the current in the circuit. A shunt resistor is added to convert the CT's output into a measurable voltage. Protection diodes are used to saf eguard the Arduino from voltage spikes .show the lcLCD power ,voltage,I,VA,Q,pf also write the code
