How to use a high current solenoid with Arduino

[@NoajmIsMyName]

I wish I saw how you use the Multimeter or what ever was that but over all it was the best explanation I found in KZbin. Very simple. Spent 5 wasted hours last night. I have could save them if I had watched this.

[@casholsen5848]

You didn't say anything about the wheeling (catch) diode that should be across the solenoid. This diode dissipates the magnetic flyback from the collapse of the field when the solenoid is released. A 1N4007 or bigger would be appropriate. The diode is wired directly across the coil (as close as possible) with the cathode to the +12 supply. Additionally, the current you measured is without any load, and should be measured under full mechanical load. Neither of these should be overlooked.

[@learnelectronics]

You are correct, I should have added that information.

[@TowerMemoir]

I wish I had a Dad like you guys.

Good video - Doesn't mention that firing this for a long time will burn something out. I think if you have it under software control you should use PWM to reduce the duty cycle to hold it in place. No expert, but I believe this is how modern pinball flippers work!

[@learnelectronics]

+simeon2020 very true

[@TangodownNZ]

Thank you. Can you do the same video with a solid state relay and se555. This is used for fully auto and semi auto for an arcade light gun. You don’t need the gun. It would just be good to see how to wire the circuit. Thank you

[@davidbolha]

A Chladni plate would be fine to attach it to the core of the solenoid. Then electronically control the oscillation via Arduino to get those cool fractal geometry patterns to appear on it. 🤔😉😆

[@JustMe-bu8pu]

Glad you saw the O-Ring from the "Slow Boat" video. I kept asking myself if you saw it. :)

[@learnelectronics]

I found it after a few minutes lol

I've just finished a project using very very simular pieces. saw you ran into the same issue as me... hold the solanoid open too long and you burn out the transistor and it locks open. hense why you had to flick the power off the 2nd time to get the release. This can be solve in a number of ways; heat sinking the transitor (this only really gives you more time), using a higher rated transistor or switching it for a relay.

[@anandjoshi8554]

can i use a solenoid valve push pull for quick push and pull....within 2-3 sec time? ( like using it to deliver one teaspoon senitizer liquid.

[@ThePlacemat]

@@anandjoshi8554 yes you can. I have one set up to literally flash open closed with less than a second between.

[@anandjoshi8554]

@@ThePlacemat thanks

[@anandjoshi8554]

@@ThePlacemat I have purchased 3N power 12v dc push pull solenoid, lets see if can do the work!!( may be higher 25n or so would be good !!) Which connector would fit to blue colour relay modules in place of jumper /dupont / berg housing connectors ??(2.54 mm pitch ) good firm connection

[@theskepticcoder7883]

do we need the transistor ? i bought one but i think it is broken can't i do it with out one

[@Schnurzbolz]

awesome, exactly the infos i need! thanks^2!

[@Mercento]

i am sorry but i don't understand how everything works..how does the transistor help again? Why can't i use a relay?

[@KyrychenkoAnton]

Interesting, can solenoid be powered only by arduino (no additional power), using capacitors? So it will have some delay till capacitor fully charged to uncharge 750mA and 11v of course, but still, is it possible?

[@stewedapple]

Would a small electrolytic cap on the power rail be a good idea?

[@ineedmorenaruto]

can you make it faster with more current or would it fry?

[@Gvtteddybear]

How much can a solenoid like this push? Could I use it to make a robot hop

[@profarlon]

I expected for the high current. I think 0.6A no too much. It's quite normal to small solenoids. I thought you would use Mosfets

[@hariharanramamurthy9946]

hi i am using diode kn2222a but is burnt out everytime i try with new diode

[@gianlucafinotti1948]

Nice. A couple of things: 1) Should I plug it to an external battery? If so, what kind of battery? 2) What kind of transistor should I use? Would the TIP120 Power Darlington Transistors work? Thank you

[@gianlucafinotti1948]

P.S. I would like to use a Mini Push-Pull Solenoid - 5V and a Small Push-Pull Solenoid - 12VDC. Could you tell me what kind of battery is needed for each one of those? Thank you again.

[@jasoncarter3921]

If my solenoid will be at distance, is it preferred I make the wires on the 5v side long or should I make the 12v side long?

[@lucafredella2486]

Hi! Can I have circuit schematic, please?

[@dwpetty3723]

Would be nice to see some code used.

[@learnelectronics]

void setup() { pinMode(2,INPUT); pinMode(4,OUTPUT); } void loop() { bool button = digitalRead(2); if(!button){ digitalWrite(4,HIGH); delay(3000); digitalWrite(4,LOW); } if(button){ digitalWrite(4,LOW); } }

[@Bobby-lv2kr]

So how powerful is this solenoid ? I was planning to buy few

[@learnelectronics]

+B Bobby good enough to open a lock, I don't have precise figures

[@bozhidarhristov6998]

Not very powerful, about 5N or 600g of force at the top and then it drastically decreases when almost at the bottom is about 200-250g

[@EkelundDK]

It would be cool to have the schematic. Can I see it somewhere?

[@learnelectronics]

I did not make one, sorry.

[@benq967]

Any chance you’d be willing to make one?

[@jankohlhase4201]

hey, how is the Code Looking like?

[@kaustubhbodake12me1shift4]

Need large amount of solenoid

[@riseoftech4k332]

this this really cool.. good job!!!! i also did an arduino related tutorial... could you check it out and tell me what you think, thanks

Did you just run a marathon ?

Read the description. Pay particular attention to part where i explain my congestive heart failure.
