I'm building a backyard aquaponics system that has 4 beds that flood and drain one after the other continuously. I'm controlling it with an arduino, but I'd like to daisy chain the solenoids together so that they don't rely on the arduino to function. The arduino would then just be responsible for starting and stopping the system and monitoring other signals.
Step by step:
Step by step:
- Arduino outputs small voltage to optocoupler
- Optocoupler triggers triac -> triac conducts
- Solenoid opens -> tank fills
- Water opens float switch, breaking current flow ->triac stops conducting
- Float switch opens -> arduino stops voltage to circuit -> arduino applies voltage to next circuit.
- When circuit shuts off, solenoid closes -> tank drains via siphon
