Hello friends, hope you all are fine and having fun with your lives. Today, I am going to share on How to measure Frequency using Arduino board. Its quite a simple tutorial but is an essential one especially when you are working on some power related project. Because in Power projects, you have to measure the frequency of AC voltages. I was working on a project in which I have to do dimming of AC Lamp so in that project I have to measure the frequency of AC signal.

I have designed this project using Arduino UNO and have simulated in the Proteus software, which you all know is my favorite simulating software. 🙂 The code is also quite simple which I have given below for download. The simulation is also included in download package but again I suggest you to design it on your own. If you got into any trouble then ask in comments and I will try to resolve them. Anyways let’s get started with How to measure frequency using Arduino.

#### How to Measure Frequency using Arduino ???

• You can download the simulation for this frequency measuring by clicking the below button:

Download Project Files

• Now let’s design this project in Proteus. So, first of all, design a simulation as shown in below figure:

• The small block attached with the pin # 2 of Arduino is a frequency meter.
• We can create any kind of frequency signal using this component.
• If you double click it then its properties will open up where you can change the frequency as shown in below figure:

• You can see in the above figure that I have setted the Clock Frequency to 2000 Hz.
• Now, let’s design the programming code for this project. So, paste the below code in your Arduino software:

• Now using the above code, get your hex file from Arduino software and upload it in your Proteus software.
• Now once you are done then run your simulation and if everything goes fine then you will get results as shown in below figure:

• Now you can see the LCD is showing the same frequency as we set in the properties of the frequency meter.
• The code is quite simple, I don’t think it needs any explanation but if you get into sme trouble then ask in comments.
• The below video will show you this project in detail:

So, that’s all for today. I hope now you know How to measure frequency using Arduino. So, will meet you guys in the next tutorial. Till then take care !!! 🙂
