Microcontroller-Modified Microphone
- PragmaticPulp 5y agoCool project! Though I have to say it’s kind of funny to see a powerful microcontroller with custom firmware used for something that you can get cheap, dedicated ICs for. Capacitive touch is easy to do with any number of ICs, no firmware required.
- scoates 5y agoThanks. Probably useful to remember that this isn't a production run of thousands of units, and I already had the WROOM board on hand…
