How it works
The Simple Sprinkler depends on 2 conditions to properly function: the sprinkler system must be enabled and it must have a sufficient supply of water. Of those 2 conditions, they are dependent on a further 4 conditions.
- A (Rain)
- A = 1 (Currently raining)
- A = 0 (Not raining)
- B (Water Supply)
- B = 1 (Sufficient water available)
- B = 0 (Water supply insufficient)
- C (Soil Moisture)
- C = 1 (Soil is already moist)
- C = 0 (Soil is dry)
- D (Time)
- D = 1 (Current time is within watering period)
- D = 0 ((Current time is not within watering period)
How to test
Adjust inputs A through D (IN1 - IN4) to see which combinations toggle the LEDs. For the sprinkler to fully function both LEDs must be lit. The truth table is included in README.md.
