The breadboard for the water tower has sat on my desk long enough that it finally transcribed itself into a diagram to start making the circuit permanent. Despite the apparent complexity, it is in fact just four simple circuits mediated by software in the microcontroller:
- The switch for the valve to start the whole operation.
- The motor to drive the float.
- The limit switch to help find the top of the float when initializing the tower.
- The MP3 player to make the gushing sound.
I’m certain this could all be achieved with hardware, but the microprocessor makes it easy for folks like me who never took the time to learn electronics.
