Arduino Oscilloscope DIY Homemade

Introduction

Arduino Oscilloscope DIY Homemade using Arduino Nano, 5110 LCD Module, resistors, capacitors, and Vero board is a very simple and cost-effective tool. It not only saves money, but it also saves time, since it is easy to create a simple oscilloscope with this device. This article provides a comprehensive guide to creating your own Arduino Oscilloscope DIY Homemade.

Before we get started, let’s first understand what an oscilloscope is. An oscilloscope is an electronic instrument that is used to measure and display signals graphically. It is commonly used in laboratories, medical fields, engineering, and electronics industries. An oscilloscope is an essential tool for testing circuits, monitoring signals while debugging, and testing electronic components.

There are different types of oscilloscopes available in the market, but they are typically expensive. However, with the development of the latest embedded technology like Arduino, it is now possible to create your homemade oscilloscope at a minimal cost.

Once you have all the components, you can begin by assembling the circuit. Start by plugging the Arduino Nano into the Vero board. Ensure that it is placed in the right direction. Connect the 5110 LCD module to the Vero board as well. Now take rest of the parts provided in the components list and connect them according to the circuit diagram provided above.

Arduino Code Uploading & Testing :

We have completed our circuit here. The remaining work is to upload the code to Arduino. The code can be easily downloaded from online sources or from GitHub. Once the code has been uploaded to the Arduino, the homemade oscilloscope is ready to use. The link to the Arduino Code is already provided in the Components List section.

To test the oscilloscope, connect the signal you want to measure to the A3 pin of the Arduino. Then adjust the potentiometer attached to A0 to adjust the sensitivity of the oscilloscope. This will vary depending on the input signal being measured. The final result will be displayed on the 5110 LCD module.

It is important to note that the oscilloscope’s accuracy is dependent on the quality of the components used. Also, the Arduino Nano has limited processing power, which means that the sample rate of the oscilloscope is low. However, it is still an excellent tool for beginners who are looking to explore the world of electronics without breaking the bank.

Conclusion

Creating an oscilloscope using Arduino Nano, 5110 LCD module, resistors, capacitors, and vero board is an excellent way to save money while having a useful tool for testing and debugging electronic circuits. Although the oscilloscope has its limitations, it still performs excellently in simple applications. It is a perfect DIY project for hobbyists, students, and anyone interested in electronics. With this guide, you should have everything you need to create your homemade oscilloscope.
