Wiring

NOTE: Do not use more than 7 volt to operate the DC motors!

1. Motor driver

1.1 For L298N motor driver

+5v  --- leave open
+12v --- LiPo 2s battery 7volt (+) 
GND  --- LiPo 2s battery 7volt (-)
ENA  --- insert jumper (enables OUT1,2)
IN1  --- Arduino pinMotorLeftPWM  (see code)
IN2  --- Arduino pinMotorLeftDir  (see code)
IN3  --- Arduino pinMotorRightPWM (see code)
IN4  --- Arduino pinMotorRightDir (see code)
ENB  --- insert jumper (enables OUT3,4)
S1   --- insert jumper (enables 5v regulator for +12v voltage input)
OUT1 --- left motor (+)
OUT2 --- left motor (-)
OUT3 --- right motor (+)
OUT4 --- right motor (-)
