12V 1/2" Inlet Feed Water Solenoid Valve N/C (1/2 straight valve)
Description:

Have you ever wanted to control the flow of a liquid using your computer or microcontroller, but didn’t know how?
Well, here’s how: The 12V solenoid controlled fluid valve. Simply connect a fluid source to the fluid input then once the 12Vdc is applied the fluid will start to exit until the 12Vdc signal is removed.

If your signal is 5V , then you can use relay 5Vdc to control the 12Vdc from your microcontroller.

Specifications:

Voltage: 12V DC
Rated Power: 5W
Pressure: Max 8 Bar
Operation model: Normally closed
Port Size: 1/2''
Fluid temperature: 0-100
Usage: water and low viscosity fluids
Flow characteristics: 0.2Bar>1.5L/min 1Bar>7L/min 3Bar>12L/min 8Bar>20L/min;

What's in the box?:

1 x Water Solenoid Valve

Please note:

The actual valve size in the unit is smaller than the port size as you will find with most taps.

ULN2803A: 8 Channel Darlington IC - Solenoid, DC & Stepper Motor Driver (Darlington stepper driver IC)
Description:

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. The inputs can be driven by 3.3V or 5V logic and the IC fits nicely in any breadboard or perfboard.
 
Please note, this is an 'open collector' driver - it can only be used to connect the load to ground and there will be a 1 Volt (or more) 'drop' across the internal transistors.
 
This is a genuine Toshiba part, not a cheap replica! 
 
The ULN2803: 8 Channel Darlington IC (Solenoid/Unipolar Stepper Driver) Features:
  • The ULN2803APG / AFWG Series are high−voltage,high−current darlington drivers comprised of eight NPN darlington pairs.
  • All units feature integral clamp diodes for switching inductive loads.
  • Applications include relays, hammer, solenoid, unipolar steppers, lamp and display (LED) drivers etc.
  • Output current (single output): 500 mA (max)
  • High sustaining voltage output: 50 V (min)
  • Output clamp diodes
  • Inputs compatible with various types of logic.
  • Package Type−APG : DIP−18pin

L293D Dual H-Bridge IC - Solenoid, DC & Stepper Motor Driver (L293D IC H-bridge)
Description:

The L293DNE Dual H-Bridge IC is able to run four solenoids, two DC motors or one bi-polar or uni-polar stepper motor, with up to 600mA per channel!
 
Each chip contains two full H-bridges (four half H-bridges) which means you can drive four solenoids, two DC motors bi-directionally, or one stepper motor. Just make sure they're good for under 600 mA since that's the limit of this chip. They do handle a peak of 1.2A but that's just for a short amount of time. What we like most about this particular driver is that it comes with built in kick-back diodes internally so you dont have to worry about the inductive kick damaging your project or driver
 
 
The L293D Dual H-Bridge IC - Stepper & DC Motor Driver Features:
  • Dual H-Bridges - run four solenoids, two DC motors, or one uni-polar or bi-polar stepper motor
  • Output Current: 600mA per channel (1.2A Max)
  • No of Channels: 4
  • Input: 5V Logic
  • Supply Voltage Range: 4.5V to 36V
  • No. of Pins: 16
  • Operating Temperature Range: 0°C to 70°C
