Standard Breadboard, Terminal Block, 14AWG connected plug, Jumper Wires, and other tools needed to do circuit work

3D Printer for enclosure

Place the voltage sensor, current sensor, screen, and Arduino on the breadboard. Make sure they are separated for room for the jumper cables

Connect the current sensor's OUT to A1 on the Arduino, 5V to the 5V rail, and GND to the GND rail

Connect the voltage sensor's OUT to A0 on the Arduino, 5V to the 5V rail, and GND to the GND rail

Connect the screens SDA to A4 on the Arduino, SCL to A5, 5V to the 5V rail, and GND to the GND rail

Connect 2 GND to the GND rail, and 5V to the 5V rail

Strip the plug cable to unveil the 3 wires. Connect the live wire to 1 side of the terminal block, and the neutral to a different block. Then, 2 jumper wires from the live to the L of the voltage sensor and 1 port of the current sensor are connected from the other side of the terminal block. Then connect the neutral from the other side to the N of the voltage sensor
