So in here, i’m going to show you the final project in 7th grade, it is the waterplant, all the way back to catching fruit, the water plant uses water pump of course, and the sensors, relay module, soil moisture, and the arduino, some of we call it brain somehow(is it), anyway it detects the soil if it dry or wet, if it dry, the relay will send the power using the battery, to the water pump and it will pump the water until the dirt wet, and empty it, if it detects wet, he will not send anything to the relay, and the relay not power up the water pump and then the water pump is not sending water to the soil
