Welcome to this course. This course will teach you how to make your own Arduino Based Real-Time Oscilloscope at home using Few switches some components, This Guide will take you in a step by step manner to know what each component is, why we use it, what it does and how to wire it up, starting with the basics of Arduino and ending with displaying data on Real-Time Oscilloscope. You will know what is the actual working principle of a Real-Time Oscilloscope, what it needs to be coded, and how to interface - wiring -and code all parts correctly so that you can adjust the Real-Time Oscilloscope using different buttons in which each of the buttons will output different signal. Learn and have fun Practicing Arduino by Making Your Own Arduino Based Real-Time Oscilloscope in a Step by Step Manner After this course, you will be able to make your homemade very own Arduino Based Real-Time Oscilloscope and the choice is yours to use it and apply it with any application that comes to your mind. All connections are explained in detail, and you can choose the sound level for each signal and the number of Real-Time Oscilloscope buttons to be used.
