So this is one of the fastest completed projects because we only need to wire the cables and install the cables to the io bit after that when the relay is turned on it will connect to the dc pump and will emit a lot of water to moisten the soil and plants. How the watering working so if you already wired in the cabel you need to turn on the io bit and than after that the relay will respons and the soil mosture will calculate the moisture and if the plant dry the dc pump will on and will emit the water. And in one team we have 4 people namely me tsaqif khalifa and fadhil and we have the demo video that you can watch on youtube and than we have like many of components we have jumper cables relay dc pump microbit and io bit
