AC Over Current Protection Circuit using PZEM004T and Arduino uno Project

Hi friends welcome to my new video in this video I am gonna to make A C overcurrent protecting circuit, with the PZEM004T and arduino nano. with these devices we can protect AC appliances by predefined current value. I hope you will enjoy this video, so without wasting time let's start this video if you are new to this channel then do subscribe and don't forget to press the bell icon so you can get notified about our new videos, These are all the components need for this project Arduino Uno PZEM004T Push button switch 5v single channel Relay/Circuit breaker LCD display Some jumper wires let us see the wiring diagram of this project RX and TX terminals of PZEM004T to digital pin number D8 and D9, then VCC to +5 volts as operating voltage and ground to ground. after that three push buttons are connected to D3, D4 and D5 respectively and other terminals to ground for increment on/off and decrement of current setting respectively. in the next LCD display is connected to 5 volts as operating voltage, SCL to A5 and SDA to A4 for I2C communication respectively for a power circuit, 230 volt AC is connected to PZEM004T and load terminals is connected through a current coil , N O and common terminal of single channel relay for cutoff supply during overload condition Thanks for watching, please do subscribe!!
