Absolutely. You power a ULN2803 with 24VDC to pin 10; and ground to pin 9. That will power the all the 8 transistors (outputs) as you say "high" to the respective pin... (RTFM !!!!) Example: Then a pin from your uC to pin 1 will energize a solenoid on pin 18, and so on...: ULN2803 pins: in-> out 1 -> 18, 2 -> 17, 3 -> 16, 4 -> 15, 5 -> 14, 6 -> 13, 7 -> 12, 8 -> 11, don't forget diodes & resistors to prevent smoke...
yeah they even perform internal clamp diodes, while being specially designed for solenoids, relays and similar loads. With only 4 pins from your microController ("uC") you can chain unlimited 74595 (hs, hc..) chips, each chip provide 8 new pins (solenoids)... then you power them with 2803 or 2003. A neater solution is TPIC6C595 which extends & powers 8 pins in a single chip. I play my 88 keys piano with a single uC and 11 o these chips. So I play MIDI files from my laptop on my wood piano.
DARGS001, 1.) solenoid coils uses a different type of wire that has "insulation" resistance on the coil wire or something so it doesn't get burned up when left turned on held on for a period of time? 2.) How do you measure the solenoid "Torque" to know how much the power of the solenoids release pushing out strokes to know how strong it releases the solenoids plunger?
solenoids are coper coil electromagnets w/ a ferromagnetic rod in the middle. control of direction is easy, just switch the leads. to control velocity (or acceleration due to the magnet) you would want to change the amt. of current flowing through the copper coil. a square pulse would be easiest i think, but if you needed more precise behavior you could probably change the shape of the pulse.
100ma of current is a lot for a light weight robot. the low cost and simplicity of a solenoid is great but the power requirements will probably kill me. need it to deposit something onto a surface, not much requirements in the way of force.
I was wondering if you had a circuit diagram for this custom MOSFET board that you were willing to share! I am trying to build a board to control 10 12V solenoids, and am having a lot of trouble doing so.

You can't use ULN2803. When all solenoids are turned on you can get ( at best ) 175mA per channel and not 500mA. It would be great for you to try though. :)
you guys suck. of course you could push these things at 40hz. its all tradeoffs. you need to ramp up the voltage and current. that'll generate heat. so you cool it down. dont give people shit for having wacky ideas.
hi, why didn't you just transistors array like ULN2803 ?? each of them provide 8 simultaneous channels with up to 500mA per channel, that is more than enough for driving even bigger solenoids than those in the video. It's a cheaper and simpler solution to your task... and btw, nice job.
Im building a multiple security locking system with multiple 5W 24V mini solenoids each locking their own device. Im intending on running them from the 100% arduino compatable EtherMega uC. I was gonna build a circuit from scratch to control the signals from the uC to the solenoids with some npn transitors...should I be using the ULN2803 instead? I don't quite understand how I would provide the extra power for the solenoid using this chip as I would making my own circuit.
Hi dargs001, How can you make the solenoid work continuously. I have a 24V Pull Action Solenoid. But it will only work once when i supply voltage to it. Is there a way I can make the solenoid work continuously like in your video? Many thanks
Hi everyone...! I'm living in korea. i wanna buy that small solenoid. can you tell me where can i fine it? i tried to purchase from the many website but it's different.
why are these called push-pull solenoids? i could see them pushing but how would you make them pull? there's no way to attach anything to the other end
Good question.. Adafruits description says it "pull (from one end) or push (from the other)".. You would have to get creative to affix to the ends, perhaps drilling a hole through or a using a collar of sorts....
I haven't got one handy to test, but it's possible it could work, would probably depend on the power supply voltage/current. Perhaps ask on the adafruit forum, or check out some other peoples projects like this one: ME102 ChalkJET: The Epic Chalk Spraying Machine!

wtf
I'm needing to learn how to use these in a laser show project I'm building.
what is the speed of solenoid work in 1 min
Can you please let me know the technical details or sketches of the project
Didn't know about the ULN2803.. I'll get one and try that next! Thanks for the tip!
DARGS001,

This is really awasome. Is it possible to show how to build this. Which Arduino Board u have used and how to make this circuit connection
are these solenoids powerfull enough to spray a Liquid Ass bottle?
@@jackv89 in fact mini rc servos can do the job

can we apply pwm signal for incremental pushing or pulling? or are all full on or full out at fast speed or proportional to voltage?
What type of solenoid is it? I hope you will reply to this comment thank you very much
Sounds like someone at their first lesson on how to tap dance.

Dear Sir I need you help I am working on a project based on solenoid matrix. can you help me?
I don't know why, but i was mesmerized by this. lol
Ahh so thats where they got the choreography for 'Riverdance'.
what voltage and amps are you running them on?
You can't use ULN2803. When all solenoids are turned on you can get ( at best ) 175mA per channel and not 500mA.
It would be great for you to try though. :)
I need to do this with 4 solenoids from 0:33 to 0:40 in the video. and to vary the speeds. please, how do I do this?
I need to do the exact same thing.
Could you link to the sketch? I'd like to do something similar to this but need some help getting started.
What is the maximum frequency? i.e. how many on/off per second at maximum? Could they make 40 "click" per second?
Are you fucking kidding me?
I ment that 40/s is ridiculous.
oh, I see, that makes that post useful
you guys suck. of course you could push these things at 40hz. its all tradeoffs. you need to ramp up the voltage and current. that'll generate heat. so you cool it down.
dont give people shit for having wacky ideas.
I've just added the link in the description.

Try a video of Gene Kelly or similar in the background?
Can you control somewhat velocities through 2803?, or it is just an ON OFF signal.
Thx in advance

क्या इस पुस पुल मोटर्स मिल सकता है
nice video, where did you get the solenoid?, what is the price?, are there smaller solenoids?
Thanks

Can you post a link about it, or where can I find information about it.
Circuit diagrams etc...
Thx again
I am a little late to the party, but do you have an Arduino code that you maybe can share with me? Thank you in advance :D
Is it just on an off or can you adjust the push and pull speeds separately?
you could build a tiny v12 solenoid motor !

Yes,you are right.

Jack Vero dam your small minded ever heard of coupling ? or milling drilling ? thats all you have todo
Hey dargs001,
I am doing an assignment and want to do this. How do i do this? Can you send me the code?
What model of solenoids are those?
fantastic, really inspiring, thank you!
What is the torque on these guys?
...puttin' on the Ritz!
How powerful are these?
are solenoids powerfull enough to push the button of a WD40 bottle ?

dargs001 Thanks man i gonna check it out !
yeah definitely
Now make them sound like Star Wars's "Imperial March". 😎😇🤗😆😅
makes me want to dance :)
you can, using PWM technique
Minecraft piston
That's funny! "These are like toggle solenoids" was my initial thought about pistons the first time I played Minecraft.
I liked the part when it went "clack".
put it on piano and play piano whit it :D
the flunger no good
now u can tapdance with them
wow
That's Cute !! It reminds me of a bunch of Hot Chicks in a synchronized swimming event :)
Riverdance :-) czcams.com/video/HHNZuj6U8jo/video.html
It ia beautiful... Sob2
Just kidding. Hohoho
:-)
Didn't know about the ULN2803.. I'll get one and try that next! Thanks for the tip!
What circuit do you use to control ?? can it be set for different time?
can they be controlled wirelessly?
