Versano

I needed a handy multimeter which can be carried easily anywhere. I wanted it to be small and a miniature one in camparison with the normal multimeters.With hours of coding and circuit designing I ended up with making a device which can measure voltage drop, resistor ,battery voltage, and so on.It was quite difficult for me to make a device which can perform all these function at time but I succeded in doing so.

A day later an idea struck me that why not to make this multimeter as a multitasking device which can perform various function by updating the code. I thought over this and edited the PCB and added some extra components to it.

After editing and customising the PCB i finally ordered the PCB on pcbway.They are awesome PCB mnufacturers from china.They provide high quality PCB at $5 for 10 pieces.I got my PCB's in a week and they were really nice.

This is a device which can perform various funtions.It can be manupulated into different devices.As I said eariler that this can be used as a multimeter, but beside this it can be used as a music player.Though this cant be used as a professional music player but it could produce different tones.By pushing different buttons new tones are produced.

Next it can be used as a calculator, numbers will be displayed on the oled screen and user can select different numbers and select operations using the potentiometer.It can perform four operations on numbers addition, subtraction, multiplication and division.It gives output correct up to two places of decimal.

It can be used as a gaming console for example i created a pong game.It is fun to play games this device.

By adding a RTC (Real Time Clock) module to the device it can display time.

It can be used as a virtual keyboard. Alphabets will be displayed on the oled screen. We just need to select the alphabets and the device will display the text in a scrolling manner on the screen.

As it is a small sized device it looks techy and and it will be a fun to use this.Isn't this wonderful that a small device which can perform these many functions together.

.Finally I named this device as VERSANO it is a abbreviation of versatile nano.

Supplies:

Step 1: Acquire Parts

Arduino nano

OLED screen 0.96''

Push buttons x3

Male Female headers

Temperature sensor

Beep

LED

RTC DS3231

Resistors 470ohm 1k x2

Battery

Some devices used in this project are

Soldering iron

Tweezers

Solder flux

That's pretty much materials needed to bulid this project.So let's get started.

Step 2: Circuit Designing

I designed my pcb on easyeda.They provide a nice ground to design professional Pcb and its very easy to design them using features of easyeda.

Step 3: Coding

Here's the code for building Versano.

Code is easy and can be customised.It is commented so i dont have to explain the code.

Some Important Notes For coding

1.) I have older version of arduino ide.Therefore I have written the code in older version.The given codes will not be working in newer versions of arduino IDE.

So I recommend you to program your arduino in arduino ide version 1.6.7. The file for older version is attached here.

2.)After you upload the code in arduino you will get a message of lower memory stability problems may occur" ignore this message its just a warning. This will not cause any problem while using.

Step 4: Libraries

You will need some Libraries during the project so here are they.

All you need to do is to extract the versano libraries file and copy all the libraries to the libraries folder in arduino software.

Step 5: Uploading the Program

Make sure all of the required libraries are installed.Set the board to arduino nano.Select the right com port.

So here you go!

Step 6: How It Works
