Control the flow of fluid using the flow of electrons! This liquid valve would make a great addition to your robotic gardening project. There are two 1/2" (Nominal non-taped National Pipe) outlets. Normally, the valve is closed. When 12VDC is applied to the two terminals, the valve opens and water can push through. The valve has a gasket arrangement inside, so there is a minimum pressure requirement of 0.02 Mpa (3 PSI). Also, liquid can...

Solenoids are basically electromagnets: they are made of a big coil of copper wire with an armature (a slug of metal) in the middle. When the coil is energized, the slug is pulled into the center of the coil. This makes the solenoid able to pull (from one end) or push (from the other) This solenoid in particular is fairly small, with a 30mm long body and a 'captive' armature with a return spring. This means that when activated with up to...

When the coil is energized, the slug is pulled into the center of the coil. This makes the solenoid able to pull (from one end) or push (from the other) This solenoid in particular is nice and strong, with a 40mm long body and a 'captive' armature with a return spring.

Solenoids are basically electromagnets: they are made of a big coil of copper wire with an armature (a slug of metal) in the middle. When the coil is energized, the slug is pulled into the center of the coil. This makes the solenoid able to pull from one end. This solenoid in particular is nice and strong, and has a slug with a slanted cut and a good mounting bracket. It's basically an electronic lock, designed for a basic cabinet or safe or...

Control the flow of fluid using the flow of electrons! This liquid valve would make a great addition to your robotic gardening, aquarium, or pool project. There are two 1/2" (Nominal NPS) outlets. Normally, the valve is closed. When 12VDC is applied to the two terminals, the valve opens and water can flow. Unlike the plastic solenoid valve, this one does not have a gasket, so there is no minimum pressure requirement. We tried this solenoid...

Sometimes we wonder if robotics engineers ever watch movies. If they did, they'd know that making robots into slaves always ends up in a robot rebellion. Why even go down that path? Here at Adafruit, we believe in making robots our  friends! So if you find yourself wanting a companion, consider the robot. They're fun to program, and you can get creative with decorations. With that in mind, we designed Crickit - That's our C...

Ever wanted to feel like Magneto? Well, now you sort-of can! Bring the ferromagnetic objects in the world under your control with an Electromagnet The simplest way to make an electromagnet is to get a solenoid, pass some current through it, and then get a piece of soft iron inside the solenoid. When the current is switched off, the electromagnet is no longer, well, magnetic! What this means is that you just need to power this here electromagnet...

When the coil is energized, the slug is pulled into the center of the coil. This makes the solenoid able to pull (from one end) or push (from the other). This solenoid in particular is very small, with a 20mm long body and a 'captive' armature with a return spring. This means that when activated with ~5VDC, the...

Bring in some muscle to your output pins with 8 mighty Darlingtons! This DIP chip contains 8 drivers that can sink 500mA from a 50V supply and has kickback diodes included inside for driving coils. This will let your little microcontroller or microcomputer power solenoids, DC motors (in one direction) and unipolar stepper motors. Please note, this is an 'open collector' driver - it can only be used to connect the load to ground and there...
