This is my first real Arduino project, and I have a question for you all. In all of the tutorials I'm reading about controlling a solenoid with an Arduino, it seems that people are using TIP120 transistors. What I have gathered is that this is done to solve the problem of the external power supply (usually batteries) not being able to provide sufficient current for the solenoid, which has a relatively high amp-draw.
In my case, however, have a pretty nice power supply that I'm going to be using to power my solenoid(s). The PS is a Mean Well SE-600-12, which can easily supply the amps that the solenoid needs.
My question to you all is how do I safely remove the TIP120 transistor from the following wiring/circuit diagram, in order to make everything work with my power supply?
Thanks a lot!
