What is a follower?Because if you place the load on the emitter it becomes a follower instead of a switch.

1 time I tried using a, 470 ohm resistor connected to the base of a tip110 transistor, it wouldn't turn on a mabuchi 555 motor. Why? I measured base current it was 16 miliamps.You should put the motor on the collector of the transistor, and the base resistor should be calculated to provide 1/10th of the needed motor current.
You will probably want to use a Darlington, or a MOSFET.
Ok I see you are using a Darlington, in that case you might get away with a 1k resistor.
Why is mosfet better than a bipolar junction transistor?You should put the motor on the collector of the transistor, and the base resistor should be calculated to provide 1/10th of the needed motor current.

A BJT is a current controlled device. A MOSFET is a voltage controlled device and the only current drawn from the driver is gate charging current.Why is mosfet better than a bipolar junction transistor?
Oh no, I recall a heated discussion about this topicA BJT is a current controlled device. A MOSFET is a voltage controlled device and the only current drawn from the driver is gate charging current.
By driver you mean the arduino?A BJT is a current controlled device. A MOSFET is a voltage controlled device and the only current drawn from the driver is gate charging current.
If you use a MOSFET, you need Vgs to be low enough that you can drive it hard enough to have a low on resistance. When driving with an Arduino, you need a logic level (low Vgs) device.
I plan to make sure the transistor is working properly then build a h bridge to reverse current flow.How do you plan to reverse that?
This video shows connecting arduino to a 12V device with mosfet.The motor has a voltage rating of 12 volts. I already mentioned I am using a 555 mabuchi motor
