Gravity: MOSFET Power Controller
In most Arduino projects, relays are the first choice to drive some large current device. It requires a certain amount of current to drive the internal coil to pick-up contact. But for some MCU, like Intel Edison, Intel joule, lilypad, Raspberry Pi and other microcontroller with limited amoun...
12V Solenoid Valve 1/2
This 12V normally closed solenoid valve controls water flow through a 1/2″ (DN15) inlet and outlet. It remains closed when unpowered and opens when 12V is applied — no polarity distinction is required. Pair it with a Gravity Water Flow Sensor (1/2″) for real-time flow monitoring in automated syst...

A 10-pack of 1N4001 general-purpose rectifier diodes — one of the most widely used power diodes in electronics. Rated for 1 A continuous forward current and 50 V peak reverse voltage with a typical forward voltage drop of 0.7 V. Key Features 1 A Forward Current – Suitable for most low-power re...
Voltage Regulator - 12V
The L7812 is a three-terminal positive voltage regulator with a fixed 12V output. It provides stable local regulation with built-in protection against overcurrent, thermal overload, and short circuits, making it a reliable choice for powering 12V components in your projects. With a maximum outpu...
12V Solenoid Valve - 3/4
This 12V DC solenoid valve controls water flow through a 3/4″ threaded inlet and outlet. It is normally closed — fluid is blocked until 12V is applied to the fast-on spade connectors on the solenoid coil. Connect it to a pressurised water source such as a garden hose or mains supply for automated...
Passive PoE Cable Set
Integrating Ethernet support into your project is a great way to relay data through a local area network and even bounce information out to the internet.
