Hi all,
I'm looking for a bit of assistance with a small project i'm building.
I have a small solenoid piston pump that i'd like to control using a PIC microcontroller. The pump runs off 12V and is rated at 5W.
I have created a basic circuit that drives the pump using a BJT and a relay circuit. This works well but i've been told that i can do away with the relay by choosing a different transistor. This will allow me to reduce the physical size of the circuit.
I have limited experience with transistors therefore was wondering if someone could help with specifying the transistor and how to wire it up. I have included the circuit diagram of my current circuit.
Thanks in advance!!
