## **Prueba PZEM-004t con Arduino UNO + Shield Ethernet W5100**

I was really a bit away from **Arduino** in my last tests, but I decided to buy and try one of the most famous or used plates, the [**Arduino UNO with the Shield Ethernet W5100**](http://s.click.aliexpress.com/e/b7nMzX9I) both were so cheap that it was impossible not to buy them.

### **Materials and Where to Buy**

### **Mounting**

### **Arduino IDE Code**

Although this case will not use the [**Ethernet Shield**](http://s.click.aliexpress.com/e/b7nMzX9I) features such as **LAN communication** and **microSD**, it must be borne in mind that the [Ethernet Shield](http://s.click.aliexpress.com/e/b7nMzX9I) works by SPI bus, which uses pins 10 and 11 of the Arduino UNO, for this reason and to avoid conflicts **SoftwareSerial** library that generates a new port to communicate with the [**PZEM-004T**](http://pdacontrolen.com/review-and-cooperation/) uses the** rx (8) and tx (9) pins.**Note:** Download links and/or github below.**

### **Serial Terminal**

- Output port UART0 Serial0.

Recommendation:** For a more detailed **explanation step by step** I recommend watching the full video **[**“**Review PZEM-004T with Arduino ESP32 ESP8266 Python & Raspberry Pi : PDAControl” ](https://youtu.be/qt32YT_1oH8)**available on our**[PDAControl Youtube** channel.**](https://www.youtube.com/c/PDAControl?sub_confirmation=1)
