Hi! I need four steps to be completed for this project 1) capturing audio from i2s mic (About 10 sec) The microphone is a sph0645lm4h. 2) Saving audio to .wav file I'd like to save it on the local memory of the ESP32 3) Sending audio to rest API I've already some pieces of code ready for the API communication, I'd only need the .wav to be inserted. 4) Get the response

I have attached the schematics for the circuit. I want to: * Add a micro-controller to change the voltage of VCC between 5V and 3V. * Replace K3-1296S-E1 (physical SPDT switch) into a digital one. I will: * Write the code for the ATMega32 for changing the voltage. Components: * K3-1296S-E1 is a SPDT switch * XC6206P332MR is a low dropout regulator * TYPE-C-31-M-12 is a USB connector (female)
