How to spend more time writing docs then code?
15m = doc
1m = code

/* Motor DC + Mosfet IRF520 + Servo
Materials:
IRF520 (Mosfet) + Dc motor + Batery (3V min)
diode (1N4007?)
Changed Tip122 for IRF520: Tip122 has less resistance and produces more heat

Hardware:
ARDUINO = A(port , 5V , GND)
MOSFET = M(A[port] , + , GND)
MOTOR = MOTOR(+ , -)
BATERIA = BAT(+ , -)
DIODO = D(sinal_1 , sinal_2)

MOSFET
M(port) = A(port)
M(+) = D(sinal_1) AND MOTOR(+)
M(GND) = A(GND)

D(sinal_2) = B(+) AND MOTOR(-)

ARDUINO
A(port) = M(port)
5V = null
A(GND) = M(GND) AND BAT(-)
