Problem Discussion:

When we implement the circuit on solenoid there is a problem with the solenoid which the water is not efficiently flow out from the solenoid. So we try to change the place of solenoid and we even experiment it with direct water from the hose of faucet.

We operate the solenoid to see how the solenoid operates

Testing the solenoid with direct water from hose of faucet

Direct supply of water from the faucet then it would function efficiently

Problem Solution:

From the problem above we conclude that solenoid with high pressure are not suitable for this projects because it required large of pressure to operate which the aquarium cant supply. Therefore we change the solenoid with Washer Pump which usually can be found in windshield washer car system. Alhamdulillah, the problem settled.
