Audio Level Meter with RISC-V CH32V003


Listen Later

I show how I made an audio level indicator for my synth project. It replaces LM3915 with improvements while using a minimal number of components. The display consists of 20 orange LEDs. The microcontroller is a mighty RISC-V based CH32V003J4M6 in a tiny 8-pin package.
