Arduino-Powered Coin Box Is the New Way of Saving Money

Now, grab a 10K and a 4.7K resistor and affix to the cardboard circle as instructed in the video. 

Next, grab some wires, and solder to the resistors as shown. 

Now, solder the other ends of the wires to the Arduino Nano. 

Now, plug in the USB cable to the Nano and upload the all-important code. We have included the link above to the .ino file, but here it is in all its glory: 

#include

Servo myservo; // creating myservo object
int buttonPin = 11;//set button pin
int buttonState = 0; // set buttonState

void setup()
{
myservo.attach(12);// attach the 13 pin to servo
pinMode(buttonPin, INPUT); // set button to input
}

void loop()
{

buttonState = digitalRead(buttonPin); // read and save to the variable "buttonState" the actual state of button

if (buttonState == HIGH)
myservo.write(0);

else
myservo.write(65);
delay(1500);

}

Upload it directly to the Nano, as usual. 

Next, grab a small cardboard box (or build one to size). 

Mark out and cut out a circle to one face of the box. 

Next, using a hot glue gun, affix the servo motor to the box lid, as shown. 

Using the hot glue gun again, also glue the Arduino Nano to the cardboard too. 

Next, take a small strip of cardboard, and glue it to the cardboard circle as shown. 

Then glue the other end of the cardboard strip to the servo motor arm. 

The cardboard circle should now close off the hole you made in the cardboard box lid. This will act to open and close the coin box. 

Now, grab your battery holder, poke another hole through one side of the cardboard box, and feed the battery holder wires through it. Using your hot glue gun, glue the battery pack to the cardboard box.

Wire the battery pack to the Arduino Nano, as shown in the video.

Now affix the lid to the box, stick in some batteries, and play with your new Arduino-powered coin box. Hours of fun are now to be had!

Enjoy it.
