It's cheap enough and will cause less frustration than trying to tune the 555 circuit. Also, it gives you the option to add features, for example you could add a photoresistor and resistor voltage divider to an Analog input pin to only pump during the daylight hours. | |

| May 25, 2020 at 7:25 | comment | added | user1876484 | Would you mind to add a picture of the circuit and approximate values for all the different parts? This will help me to understand whether I want to try to build it or better stay with Arduino. And yes, precision is not that important in this case. Thanks. | |
