Since the current drawn by the solenoids is usually high, the switch is a must. One example of a power switch is a TIP120 IC which is very useful in these applications. You should use a switch to drive the solenoids.
1) How do you use Arduino to actuate a solenoid valve? If you have questions that are not answered in this section or the article, please send me your questions via the comments box. I have brought together the commonly asked questions about the Arduino with solenoid projects. FAQ’s About The Solenoid And Arduino Project In the loop function, we change the pin status from 1 to 0 and 0 to 1 with a delay of 1 second. The main action happens in the loop function. In the setup function, you define pin 13 as an output pin. turn the LED off by making the voltage LOW turn the LED on (HIGH is the voltage level) the loop function runs over and over again forever initialize digital pin LED_BUILTIN as an output. the setup function runs once when you press reset or power the board

This example code is in the public domain. Model, check the Technical Specs of your board at: If you want to know what pin the on-board LED is connected to on your Arduino
The correct LED pin independent of which board is used. It is attached to digital pin 13, on MKR1000 on pin 6. Most Arduinos have an on-board LED you can control. Turns an LED on for one second, then off for one second, repeatedly. Hence the solenoid will also toggle every one second. The example code toggles the Pin13 every 1 second.
Since the built-in LED is connected to the Pin 13, I have also connected the solenoid to pin 13 of the Arduino UNO. The Arduino code is the same as the one you find in the examples. Here is a simple Arduino sketch you can use to program the Arduino. > Read our article about How Easy Is It To Learn Arduino? Arduino Code For Solenoid And The Arduino Uno Project The next section will show the basic Arduino code needed to toggle the solenoid on and off. Make sure to match the supply voltage with the voltage rating of the solenoid.Ĭongratulations on completing the arduino-solenoid project connections.
