Hello everyone, i just started using arduino and new to electrical engineering too. Probably this question was asked before, but i can't find to get my head around it.
I need to control a solenoid which feeds onto 14.4 volts, from my car battery, and can have a max current draw of 11 Amps.
I want to use arduino pvm to control it's speed and control the nos flowing trough it.
I have found the circuit bellow using a TIP102 transistor but obviously that is not powerful enough for my application. Any ideas of a "bigger brother transistor i could use in the circuit bellow" or some similar circuit please?
