I need help to find out a driver circuit or a component to interface my raspberry pi 3 to 12V solenoid valve.
As I tried to take the output from GPIO 18 thereby using a NPN transistor, 1N4148 diode and a 220 ohm resistor. but I was not able to get the output.
So, now I’m in search of finding a readymade switching circuit block to control a 12V solenoid using RPi 3.
Thanks,
Bikash
Hi Bikash,
Why are you driving a solenoid with a raspberry pi? It would be much easier to control something like a solenoid from an Arduino. If the raspberry pi is needed, then control the Arduino from the raspberry pi.
Let us know how it works out!

Thanks Stephen for your concern… It worked out after using relay module in between of RPi3. To cover the mismatch on power, I used one 12V step up voltage regulator.
