ASL shield
✔ Up to 24 stairs setup availability.
✔ Fade out effect. PWM modulation.
✔ Can be connected wirelessly with more than 20 of the leading home automation controllers on the market.
✔ Ready to use sketch .
✔ Combined with Mysensors lib.
(can be included as relay, in this case no light sensor needed, just create a Day/Night scene inside your home controller)
HOW TO BUILD:
1. Follow the schematic sketch bellow to wire it up.
2. Download and install Mysensor-master(optional) and ShiftPWM -master libraries to Arduino IDE:
3. Download a sketch .
( Two options: choose sketch 'ForASLMysensorInkluded' or 'ForASLOnlyLightSensor' for controlling
day/night mode.
4. Edit code : Set number of stairs, pause between on/off, check your sensors type, adjust photocell
sensitivity (if using)
5. Upload the code to Arduino Nano.
6. Insert Arduino to ASL Shield.
7. Insert NRF24L01+ modul . ( optional )
8. Set Mysensors plugin to including mode. ( optional )
8. Power up ASL Shield.
( optional - means you can skip this step ,if ‘ForASLOnlyLightSensor.ino’ sketch is used )
