My 25th original eurorack modular synth DIY projects with Arduino nano.
Display module for watch CV , audio waveform , and harmonics.
The purpose is to enjoy watching the waveform. It is not possible to measure accurate voltage and frequency like a measuring instrument.
I plan to add VU meters, etc. by updating the software.

0:00 display example
0:24 LFO / EG mode
1:58 wave mode
3:16 shot mode
3:51 spectrum analyzer mode
4:43 specification
5:29 schematics and technical information
