I hope you took that analog meter from a ‘dead’ vintage boombox and not one that ‘just’ needed to be serviced 😠, its scale indicates both VUs and battery level. Interesting that for the 2nd example you re-did it’s original function as a sound meter (without the battery test). As for the 1st you would have to take the front off the meter and remove its scale and put a custom temperature-thermometer scale in it and calibrate it to another thermometer to accurately indicate room temperature 😉
Before start wiring, please show the schematic diagram.
Thanks for your advice
good
Thanks, glad you like it
