How can I make a battery?

You can use a battery to turn the power off or on with one button and a simple circuit.

Here’s how:

In your Arduino you can find a button on the pins marked +5V and -3V.

If you just need to turn your Arduino on or off, you can simply connect a battery with the “2” and “3” connectors to each pin. However, it takes more effort and may be necessary to solder more wires in your circuit. If you want to be really sure, you can also measure the voltages of the two wires and if you do not find one, you can just leave them be.


Now that both of these voltages are known, we just need to figure out how to power the Arduino from the battery. There are three ways you might do this:

We can just use the Arduino as a simple clock or we can use it’s ability to read a digital pin as a way to power our LED lights.

We will also need to learn what some of the Arduino’s functions really do. For this tutorial, we will use some of the “functions” that will allow you to power our LED bulbs.

What is a Arduino?

In the simplest way, an Arduino is a mini computer that will be attached to a digital pin and connected to your Arduino via a digital cable. When the Arduino receives a digital signal, it will take in a number which is called an “address” and send the address to the Arduino. (This is commonly known as Arduino mode). When done correctly, you should not need a “D” in front of the address. You can also refer to Arduino as the “Digital to Analog Converter” board.

Arduino Basics

If you do not know what Arduino really is, you may want to start with these simple Arduino tutorial:

There are two things that may seem to be very different about Arduino, but they are actually more alike than they are different. Below is a list of the three different types of the Arduino hardware.

Arduino Uno:

This small, microcontroller board which is compatible with many Arduino boards. You can access to Arduino’s Serial Port using a USB cable, which is the way to control the serial port on computers. At the same time, you can open the serial port by pressing Ctrl+Alt+Del keys simultaneously. This little Uno features an 8-colour backlit display and an “Ar
