555 Based Feeding Timer
The fish feeding timer is based on a simple monostable 555 circuit and a relay to drive the load (the return pump in this case). The circuit is setup as simple monostable 555 multivibrator, a.k.a a one shot trigger or timer.The timing period can be adjusted by turning the potentiometer.
