In this tutorial we will be controlling a solenoid with an arduino and a transistor.
Electric solenoid valve arduino.
Exchanging the transistor first flame fist test.
The solenoid we have picked for this tutorial is our plastic water solenoid valve perfect for controlling flow to a drip irrigation system but this tutorial can be applied to most inductive loads including relays solenoids and basic dc motors.
40ma is the maximum and ideally the current draw should be kept to around 20ma.
I need to take some vacation time and unfortunately while i don t have kids i have bonsais.
20ma is fine for a led but not so good for motors solenoid valves or long strings of rgb leds.
Solid brass direct acting viton gasket solenoid valve by u s.
You can use it with rtc module to schedule watering plants smoke sensors and many other uses.
The air valve contains a solenoid to control the opening and closing of the valve.
A solenoid consists of a coil of wire and when a current passes through the coil a magnetic field is induced.
A typical 5v arduino can provide 5v and 3 3v at a maximum 40ma from a single pin.
In this tutorial we will look at the basics of solenoids and how they work.
Controling a solenoid valve with an arduino.
We are going to switch a small 5v solenoid on and off in intervals.
Electric solenoid air valve.
Then we will design a small circuit that can drive a solenoid from the input output pins on your arduino board.
How can a solenoid valve be used with an arduino.
Size 8cm x 8 8cm x 5cm 3 15inch x 3 46inchx 1 97inch.
Like kids these little critters need constant care and especially water.

Https youtu be qzghmpg1hks open up the description for the viral vibe.
This is great for gardening plumbing and industri.
As my solenoid valve had threads for 1 2 while a normal garden hose is 3 4 i needed two adapters and a female.
How to use a solenoid valve with an arduino in this video we show how to do flow control with an arduino.
