Breadboard (generic)
Breadboard (generic)
Optional, or use solderable prototype board

Resistor 10k ohm
Resistor 10k ohm
Pull up resistors for i2c bus and a pull-down resistor for the Water Level Switcg
×3
Texas Instruments ULN2003a
Darlington Array for the Solenoid Valves and DC Pump
×1
12V 2A DC Power Supply
Or alternative based on your choice of DC pump / solenoids, make sure it can provide enough current
×1
STMicroelectronics L78S05CV 5V Regulator
This is only used for the i2c Soil Moisture sensors (see in the story below). Or alternative - 2A is more than necessary for this project. Follow the datasheet for your chosen regulator, this one needs a 0.33µF tantalum at input, and recommends a 0.1µF ceramic at output
