Im new to this site but am wondering on how to choose a transistor. I plan on using it in my automobile. basically i have a 5 volt digital signal coming out of the computer. I need to turn this 5 volts into 12 and figured this would be a good application of a transistor. Im not pushing much amperage but i have no idea how to figure out which transistor or how to hook up this circuit. Any help would be appreciated. Thanks!
