From the project

The open source Watering Machine device build for fun using an "old school" TTL logic with low/middle integration. Sources contains the logic design, schematics design and the PCB design

Watering machine is a device that control a watering of the garden. This particular machine provides sequential zones watering. This was made to avoid low watering pressure that can happens in case of the parallel mode zone watering.

This device is a control unit with outputs to the external valves - one per watering zone.

Used for the regular day-by-day watering. Each zone watering time interval set by the particular zone settings.
