==Introduction==
Here in this example, we’ll introduce a Microduino digital oscilloscope.
Main parameters:

Frequency response：
10Hz-50KHz
Power: 5V
Microduino-OLED display screen: 128x64
Display area: 96x64
Message display area: 32x64 (Frequency of testing signal and Vpp.)
Way of synchronization: Rising along the trigger
Scanning speed: 0.02ms/div~10ms/div (Classified by nine gears according to 1-2-5 carry.)
Hold Function: Freeze waveform display and parameters.

==Debugging==

Step 1: Build the circuit according to the schematic, as follows:

Step 4: The three keys in the schematic are used for enlarging and reducing the scaleplate of the displayed waveform and served as “OK” button respectively.

==Result==
Signal waveform can be displayed on OLED.
