hi all i am doing a project where i use PIC18f4520 to drive a 12Vdc water pump about 7A to turn on the water pump when there is no water and turn the water pump off when it is full. i will be using a 12Vdc battery as the voltage supply for this project. For PIC18f4520, it will be connect to a 7805 voltage regulator circuit as to supply 5v to the PIC but how do drive the pump? i am thinking of using L293 motor driver IC with darlington pair connect to the output of the IC to drive the motor but i dont think it is feasible at all. do u guys have any circuit suggestion?
this is the pump i am using https://bit.ly/2PWjpQt just in case u guys need to refer
