If you haven't done so, download the UTFT and UTouch Libraries, and copy them to the libraries folder where you have the arduino IDE installed.

If you finished putting your kit together, plug it into the USB cable that connects to your PC running the Arduino IDE. The oscilloscope, like my 4 channel DC DVM, will not be as accurate as a commercial unit, but it works pretty good for low voltage and low frequencies. A trigger is used to capture and stabilize the waveform on the screen, or to wait for an event before capturing the data.
In most cases you can set the trigger level to a voltage value of your choosing. A trigger signal can be generated when the signal value reaches some particular level - the trigger level. It is usually measured in volts/centimeter or volts per division. That's the measure of how sensitive the display dot is to voltage applied to the input terminals. Sweep speed is usually measured in units of time per distance, like milliseconds/centimeter or milliseconds per division.This might also be referred to as the horizontal sensitivity. These are functions you can control on most oscilloscopes: Sweep speed. Before we start building and programming, lets review some basic characteristics of an oscilloscope. We will be using the Arduino analog A0 input to sample and capture time varying signals by Writing a program that will also display those signals in a 3.8" TFT LCD touch display, and we will input data to modify the oscilloscope behavior, using the touch capabilities of the screen display. You will learn about the Arduino mega analog to digital converter( ADC). We can use an oscilloscope to observe and study signal characteristics that we could otherwise not see. Any time you have a signal that varies with time( slowly, quickly, and /or periodically ) you can use an oscilloscope to measure it, visualize it, and to find any unexpected features in it.
It is mainly used to measue time-varying signals.
