nnect arduino to battery with 12V motor - Arduino Stack
If you are using 3. 3V Arduino, then read ESP8266 WiFi and 3. 3V Arduino connection. First we need 3. 3V power supply for ESP8266. Good choice for regulator is AMS1117 3. 3V. Simple circuit is shown below. Be sure to use big enough capacitor.
Arduino misconceptions 6: a 9V battery is a good power
Connect the black lead from the battery connector to one of the Arduino's ground pins, and connect the lead from the toggle switch to Arduino's Vin pin. Snap a battery to the connector. Now your Arduino will turn on when the switch is closed and turn off when it is open (figs 5 and 6).

Create an Arduino Controlled Battery Charger
The Arduino Nano can be powered via the Mini-B USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source. So you can connect battery positive to Vin pin and negative to Ground pin directly.
