This project is mainly created to rehabilitate a garden fountain. All system is in a waterproof box, protected of the rain and the wind. The 4 LEDs and the 4x7 Segment display will be visible to maintain the feedback with the user.
The components used in this systems are shown below:
- Raspberry Pi Pico W
- 2 x LM2596
- TP4056
- 2 x 3.7 Li rechargeable batteries
- 12V Water Pump
- 12V Submersible LEDs
- Relay
- Blue LED
- Yellow LED
- Red LED
- Green LED
- 12 x 220 Ohm resistor
- 2 x 10 K Ohm resistor
- 1 K Ohm resistor
- DHT11 sensor
- IR Receiver
- 74HC595 Shifter module
- 4-7segment display
- Buzzer
- Switch
- Solar Panel
The system will be controlled with a IR remote control, but only enabling 3 buttons:
- Power ON/OFF: This button will turn ON/OFF the water pump of the fountain and the submersible LEDs in it.
- Button '1': This button activates the humidity mode, if it was not activated yet, turning ON the blue LED on the box and displaying the ambient humidity (%).
- Button '2': This button activates the temperature mode, if it was not activated yet, turning ON the yellow LED on the box and displaying the temperature (°C).

The libraries used in this project are the DHT library and the IR library, both of the Freenove repository.
