Picture above show the architecture of the Arduino Uno. With that, the input and output of the project should be in the right port.The PWM port is for the motor of the robot, Analog port is for the sensor.
In this week, I am focussing install of the Arduino Controller, the IC Regulator and battery.
The output of the LiPO battery is around 11V. Because of that, IC regulator used to reduce the 11V to 5V. The voltage for the input Arduino is directy from Lipo battery which is 11V.
