How do I connect Arduino to solenoid valve?
Arduino-Control Current Output: Transistor Activation
- Hook each transistor’s collector to one solenoid lead and plug the other solenoid lead into a common positive voltage.
- On the collector lead, run a diode (1N4007 or another appropriate device) to a positive line.
- Connect the emitter leg of the transistor to ground.
What is a solenoid Arduino?
Then we will design a small circuit that can drive a Solenoid from the input/output pins on your Arduino board. A Solenoid is a coil that when energised, produces a controlled magnetic field down through its centre. By placing a magnetic armature inside that field, the armature can move in or out of the coil.
What is motor shield for Arduino?
Overview. The Arduino Motor Shield is based on the L298 (datasheet), which is a dual full-bridge driver designed to drive inductive loads such as relays, solenoids, DC and stepping motors. It lets you drive two DC motors with your Arduino board, controlling the speed and direction of each one independently.
Can an Arduino power a solenoid?
The solenoid works with anywhere between 6-12V which is too high to use with the standard Arduino 5V. To get around this problem we will be using a 9V power supply – the solenoid will operate at 9V while the Arduino’s built in voltage regulator will turn that 9V into the 5V that it needs to operate.
Why do solenoid valves fail?
Solenoid coil failure can be caused by a number of factors. Applying an incorrect voltage to the coil will cause it to fail and may cause the coil to burn out. Electrical surges or spikes may also damage the coil. Sediment or other particles entering the valve may cause coil failure.
How many amps does a 12V solenoid draw?
For example 12 volt solenoid valve with 15 watt coil will draw 1.25 amps and if connected to a battery will have a significant power drain and will need topping up according to the power usage. Amps (current consumption) = watts (power consumption of coil) divided by 12 volts.
