Directly level it for servo/modules high power devices

Note for the jumpers near to the Power Input socket:

Both jumpers are on left side: This method will only provide regulated power to the PWROUT.

i.e. There is no voltage on Vin which is connected with Arduino .

Top jumper is on left side, bottom jumper is on right. This will provide regulated PWROUT,

adjusted via the blue potentiometer next to the PWROUT connector. Arduino Vin power will be

connected to the external power supply.

Stack up more power shield to add up different power level outputs. If your Power supply is

incompatible with your device and you need to provide power for other devices as well. Adding

another power shield will let you regulate a secondary voltage level as well.

Sample Code

This sample code needs an I2C LCD module to display the voltage.

#include <Wire.h>

#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x27,16,2);

// set the LCD address to 0x27 for a 16 ch

ars and 2 line display

void setup()

{

lcd.init();

lcd.backlight();

lcd.setCursor(0, 0);

lcd.print("www.DFRobot.com");

lcd.setCursor(0, 1);

lcd.print("Voltage: ");

lcd.setCursor(13, 1);

lcd.print("V");

}

void loop()

{
