can you help me wire a 12volt solenoid with only 9v

[ArcanePath]

I have a 3.7v tiny valve solenoid which has 2 black leads, and doesn't seem polarity sensitive. Do I still need a diode?
Thanks for the informative video

[moulikgupta]

Hi! Great video! I understand why we use all the components except the MOSFET transistor. What's the point of using the MOSFET transistor? Is it something we use to control components, as it provides a digital connection (between the Arduino and the component) and hooks it up to ground?

Good video. Always enjoy the information. Well presented.
Thank you.

Am i able to have a 3s lipo as my power supply for a 12v solonoid?

[tommasoravasi]

A 2n2222a transistor can be used if i don't have a mofset?

Hlo
I tried the project solenoid door lock using rfid and arduino.solenoid is not controlling.what would be the reason

[OliverArment]

what transistor and diode are you using

[lololoololdudusoejdhdjswkk]

Would a relay here work as well in replacement of a transistor? I thought transistors are meant for fast switching

[nathanaelculak]

I have a 12v dc 5-2 Solenoid valve that I want to control with arduino. It’s a much bigger pneumatic actuator, will this work for that.

Hi how can I add a pir sensor and i2c lcd

[jmar]

I have a 12v solenoid and a relay, I don't have any mosfet or diode on my solenoid. Which is directed to relay.

the relay is connected to the battery and solenoid, and to Arduino
relay has NO, Common, IN.

Is this safe? It is causing a random signal on my coin slot IR sensor, which is causing a count even though I'm not dropping a coin in the slot.


Please help me.... this is for my project at school.
