A Fully Assembled and working, breadboard-able Audio Oscilloscope. powered by an Arduino Pro Mini and 128x64 .96 inch OLED Display.
This Project is based on the open source schematic and arduino code by: http://radiopench.blog96.fc2.com/category55-1.html -an arduino powered Digital Storage Oscilloscope.
I needed a quick and easy way to view audio signals while bread-boarding prototype Guitar Effects (footpedals/stompboxes).
The original circuit did not include a separate power supply or power switch. Also, the original circuit would cut-off half the waveform, so I modified the circuit to include a Power Supply (voltage regulator), Power Switch and an Offset Control for centering the waveforms.
It uses a generic Arduino-compatible Pro Mini circuit board and OLED module (128X64 / 0.96 inches).
It's small and plugs into a breadboard.
I laid-out a circuit board and added a Power supply with voltage regulator (works between +3.7v to +12v), an Offset Adjustment (for centering the waveform (as some waveforms only showed 1/2 without the offset).
"Select" Switch selects between Volts-Per-Division, Time-Per-Division and Positive/Negative Trigger.
Each of these can be Adjusted with the "Up" or "Down" Switches.
Max/Min Input Voltage = 50v/0.2v Max/Min Time = 200msec/200usec
The "Hold" Switch Freezes/Unfreezes the Waveform.
There is also a readout on the screen giving the "Average" peak-to-peak voltage, and whether the signal is "Unsynced".
