DC MOTOR CIRCUIT
I decide to use Arduino for my project. And to do that. I need to understand the basic some knowledge of Electrical and Electronic.
I research about DC Motor Circuit.
Some diagrams illustrating how to use the tip120 transistor to control 12 v (actually up to 60v dc)

TIP120
Transistors are powerful little electronic switches, and when our little NPN transistors aren't power enough for your project, we have been known to use these beefy TIP120 Darlington transistors. Great for whenever you need to control medium to high-power electronics such as motors, solenoids, or 1W+ LEDs.
1N4004N
The 1N4001 series (or 1N4000 series) is a family of popular 1.0 A (ampere) general purpose silicon rectifier diodes commonly used in AC adapters for common household appliances. Blocking voltage varies from 50 to 1000 volts. This diode is made in an axial-lead DO-41 plastic package. The 1N5400 series is a similarly popular series for higher current applications, up to 3 A. These diodes come in the larger DO-201 axial package.These are fairly low-speed rectifier diodes, being inefficient for square waves of more than 15 kHz. The series wassecond sourced by many manufacturers. The 1N4000 series were in the Motorola Silicon Rectifier Handbook in 1966, as replacements for 1N2609 through 1N2617. The 1N5400 series were announced in Electrical Design News in 1968, along with the now lesser known 1.5 A 1N5391 series. These devices are widely used and recommended.
