Project: automated greenhouse
Expert45 min
Goal
Manage watering, ventilation and lighting from the readings.
Why it matters
Several control loops coexist: this is real automation.
Steps
- 01Soil moisture → pump, temperature → fan, light → lamp.
- 02Each actuator has its own threshold and hysteresis.
- 03No task may block the others (millis()).
- 04Print a dashboard on the serial port.
This tutorial runs inside the Circuitly simulator: your wiring and your code are checked automatically at every step.
